Lens Design and Assembly Defects Which Software Can't Fix

With curvature of field a lens may focus sharply in the center but the edges will focus at a different distance. The plane of sharp focus is not flat. It extends forward from the lens like a curved wave front. The curve may be simple or complex. This is determined by the optical design of the lens, not manufacturing. Better lenses and macro designs exhibit flatness of field: they do not suffer from this problem.

With de-centering every corner of the image focuses at a different distance. A misalignment of internal elements has been overlooked by quality control. To avoid de-centered lenses, some photographers routinely purchase several samples, keep the best and return the others to the retailer. Budget-priced lens adapters and extension rings can cause de-centering.

With focus shift, adjusting the aperture moves the point of sharp focus closer and farther. This is determined by the optical design of the lens, not manufacturing. For optimal results it's best to focus at actual taking aperture, which is easy with manual-focus lenses. One reason that cinematography lenses are more expensive than still lenses ? No focus shift. See Cinema Lenses: What Are You Paying For?

To get around these problems, we can shoot at small apertures and rely on increased depth of field to get everything in focus, but that's not an ideal solution since image quality starts to degrade once we pass the best aperture. Besides, sometimes we want or need to shoot at wide apertures. See Equipent Evaluators for information about good lens testers.

Browsing Monochrome Raw

Some cameras let us compose and shoot in Black & White but they save a full color Raw file. With recent improvements to Adobe Bridge, we have the option to browse images as they were made.

To view files as they were captured in monochrome, go to Adobe Bridge 2020 > Camera Raw Preferences > Raw Defaults and change from Adobe Default to Camera Settings.

FastRawViewer also lets us browse B&W photos as they were taken - in monochrome - or as they were saved - in color. As the name implies, it's a very fast application, with versions for both Mac OS and Windows. To browse in monochrome, select View > RGB/Channels/BW > BW Conversion

Selective Toning in Photoshop and Other Tools

Toned monochrome images are beautiful. With this method we can increase and decrease toning at different locations along the brightness scale. Click here to read about several tools which can improve the standard Photoshop and GIMP methods.

Selective Sharpening in Photoshop

After sharpening an image, strange artifacts often appear at the high and low ends of the tonal scale. Here's an improvement: sharpen the mid tones only.
  1. Duplicate the layer that you intend to sharpen.
  2. Select the Layer Style of the duplicate layer.
  3. Adjust the Blend If sliders to remove the low and high end of the tonal scale. The result is that only the middle of the tonal scale has been selected.
  4. Sharpen the new layer to taste.
  5. Do not merge the layers before saving. Save the file as a PSD or TIF file with separate layers intact. You can change or even discard the sharpening layer any time you like, depending on the size of your print.

Some images automatically look sharper than others. Because of visual cues, they convey an impression of sharpness. See Two Barns: One Sharp, One Not for more explanation.

3-Level Sharpening for Best Results

If you want to sharpen your image even more effectively, you can apply this principle three times over. Create 3 duplicate layers (one for each of the low, middle and high portions of the tonal scale) and sharpen each layer separately.

Selective Contrast Curves in Photoshop

Selecting specific areas for contrast adjustment in Photoshop can be tedious and error prone. The Color Range and Blend If tools can vastly improve the Curves feature, allowing us to select areas quickly according to their brightness range. Click here for details.

Adobe Camera Raw: Easy Spot Removal

Images from scanned film and digital cameras with interchangeable lenses are prone to dust. Removing spots can be troublesome and time-consuming. The Adobe Camera Raw Filter makes it much easier to find and remove spots from your images. This feature is a vast improvement over the older Spot Healing Brush.

Camera Raw Filter
In Photoshop, click Filter > Camera Raw Filter. The Camera Raw window will open: click on the Spot Removal icon on the upper right. Be sure to select the option Visualize spots. Depending on how far you move the slider to the right, even the tiniest blemishes will appear in clear relief. You will probably find it helpful to de-select the option Overlay.

Use the Size, Feather and Opacity settings to control the size of the spot, amount of blending with adjacent adjacent pixels and degree of pixel replacement. What a superb feature !

Vibration-Free Shooting with Sony Wireless Remote Control

Sony Wireless Remote Commander Shooting on a tripod for best image quality, it's not always appropriate to use the camera's self-timer to minimize camera shake. Sometimes we need to work quickly, shoot at an exact moment, perform repetitive manual focus-stacking or appear in our own group portrait.

The Sony Wireless Remote Commander is an inexpensive and portable tool which communicates with the camera's infra-red sensor. It supports remote shutter release, delayed shutter release, video start/stop, image review and deletion. Click here to watch a brief Youtube video.

MacBook Air with j5create ULTRADRIVE MINIDOCK

j5Create MiniDock The 2019 MacBook Air is a powerful and portable computer with a Retina display at a favorable price-point: ideal for travel. This model gives us two Thunderbolt 3 ports: very high performance and compact but rather inconvenient for photographers.

If we don't want to carry around a collection of adapters, we can attach a j5create ULTRADRIVE MINIDOCK or similar device. The 8-in-1 model provides an abundance of connections and is itself delightfully small and affordable.

Photoshop Tip: Solid State Scratch Disk

SanDisk Without sufficient access to fast RAM, Photoshop will hang, pause, delay, spin... etc. Photoshop really wants RAM for its scratch disk. To eliminate these problems and gain performance, your scratch drive should be very large and it should be on its own dedicated drive.

If we want a cheap and easy Photoshop scratch disk we can simply plug in an external SSD drive and specify it in Photoshop > Preferences > Scratch Disks. There should be nothing else on the drive and it should only be used as a scratch disk.

Of course it's best if we have an internal SSD with its fast on-board connection to the computer, but even an external SSD drive will be better than no separate drive at all, especially if the drive uses a fast connection like USB 3 or Thunderbolt 3. The more RAM you have, the more Photoshop will use, so get a much larger SSD drive than you think you'll need. I use a 256 MB SanDisk External SSD with a USB 3.1 connection.

Photodiox Exxy L-Bracket for Vertical/Horizontal Shooting

Exxy L-Bracket When we orient a digital camera in portrait mode on a typical tripod head, movements are restricted and the camera sits off to the side of the rotational axis. The Photodiox Exxy L-Bracket solves this problem at an affordable price-point.

With an L-bracket, shooting in portrait orientation is just like shooting in landscape mode: all tripod movements are available to us and the camera can be centered over the axis of rotation: we can stitch vertical images together to make images of considerably higher resolution. Not absurdly wide panoramas: photos in landscape mode with optimal quality.

Below is a photograph stitched from 3 overlapping vertical images made with a 42 megapixel Sony A7RII and an affordable used 75mm lens (see below). Cropped to the 4x5 ratio, the resulting file is 80 megapixels. Each section of the final image is taken from the central portion where resolution is highest. At 80 megapixels we have matched or exceeded the image quality of far more expensive equipment but we may not need that much resolution unless we plan to make and display very large prints !

Once you attach the L-bracket to the bottom of the camera, you can mount the camera either vertically or horizontally using a standard Arca-Swiss style dovetail quick-release. The rear screen moves about freely and you still have full access to the battery and memory card. Click here for a Fotodiox Youtube video which features this product.

Hoodman Loupe for Viewing Cropped Aspect Ratio in Bright Light

Blue Tape Some mirrorless cameras offer a narrow choice of in-camera aspect ratios: 2x3 and 16x9 only. If we like to compose in the 4x5, 3x4, 5x7 or other ratios, we can apply removable painter's tape to the rear of the electronic viewfinder or EVF. This works well indoors, but under bright sunshine we can't always see the EVF clearly enough for precise composition, focus and exposure adjustment.

Hoodman Loupe An affordable loupe like the Hoodman comes to the rescue. There are more inexpensive models on the market, but be sure to choose one with a diopter adjustment on the eyepiece. The Hoodman loupe works as designed: in very bright light we can effectively view the EVF. If the EVF has been masked to a different aspect ratio, we can compose in that ratio. In-camera control of aspect ratio would be ideal, but this solution will mimic that missing feature at an affordable price point.

The diopter adjustment works well and we see a clear image with no barrel or pincushion distortion. The Hoodman works nicely when the camera is tripod-mounted and we wear the loupe on a lanyard. In other words, it functions best when we use it like a loupe. There is nothing to attach to the camera which might damage the paint upon removal. For my Sony A7RII, I use the 3 inch model.

4-Way Focusing Rail for Close Shooting and Mosaic Images

Neewer Focusing Rail If you've ever tried working at short range with a small tripod-mounted camera, you'll know that minute adjustment of position can be troublesome. An affordable four-way focusing rail like the Neewer makes it easy. Four-way rails allow you to precisely move the camera from side to side or front-to-rear. Be sure to choose a model where everything is geared and the positions can be independently locked.

After shooting with a view camera for decades, many of my photographs are made at close proximity to the subject where even a slight change in camera position has a pronounced effect on composition. For example, see these photographs of Tulips which were made with a Sony mirrorless camera only inches from the flowers. Exact camera position can make or break an image.

To see a brief Youtube video about the Newer 4-way Focusing Rail, click here.

Another advantage of a 4-way focusing rail is that we can position the nodal point of the lens directly over the the tripod's center of rotation. This step is critical for making successful stitched panorama and mosaic images at less-than-infinity distance.

The image above was made from 16 exposures, employing both focus-stacking and mosaic stitching to provide unlimited depth of field and avoid parallax artifacts. For focus-stacking I use Helicon Focus and for stitching I use Photoshop. Helicon allows you to import RAW files directly: there is no need to save as TIF or DNG first (but it's faster if you do).

Professional Monitors and Calibration for Accurate Viewing and Printing

Bulls Eye Click on the bull's eye at right to view it at full size. There are 50 equal-sized steps from the center of the circle to the edge. Can you see them all ? If your monitor is calibrated properly, it should appear perfectly smooth along the entire tonal scale. If not, your monitor needs calibration. It's not good enough to discern a step-wedge with only 10 or 20 steps For high fidelity, 256 steps are best but 50 is a good starting point.

Don't be surprised if you can't distinguish 50 tones - especially at the dark end of the scale - even after profiling your monitor. Consumer grade displays can't reveal the low values because they are optimized for high contrast, brightness and saturated colors, not for optimal rendering. Want another surprise ? Try printing this image.

Apple Retina displays have high resolution and vibrant colors but can't separate low values even when set to their maximum brightness: my 2012 MacBook Air actually does a better job. Consumer grade monitors are not designed for printing ! To perceive the entire range of tones, graphhic arts professional use professional grade monitors like Eizo and NEC SpectraView. For further discussion, see The K7 Standard and Monitor Display Systems on the Piezography blog. Printing with Piezography, we can produce 256 distinct shades of gray, even though many monitors cannot.

Eizo LogoProfessional grade monitors come with their own built-in calibration sensors and software, optimized for the monitor. Professional grade monitors have their own internal LUT (lookup table) where they store the results of calibration, rather than adjusting the computer's own graphics card which is a losing proposition. You can see the difference with your own eyes.

If you don't want to purchase a professional grade monitor, it's still a good idea to calibrate your consumer grade monitor with a dedicated calibration tool and software. If you intend to make prints, be sure to choose a tool that lets you adjust the brightness (luminance) of your monitor, to more closely match the properties of your printing paper. If not, you end up wasting time and materials. These tools change frequently. For a current list of recommended monitors and calibration tools, see the Chromix web site.

For a target file which contains 256 shades of gray, you can download MicroGrayTest.tif from the Hutch Color web site.

You may find it helpful to create two monitor profiles: a brighter one calibrated for general use under office illumination and a dimmer one, calibrated for paper white and print-making. With the EIZO Color Navigator software, you can easily create these profiles and switch between them with a few mouse clicks. Monitors which have their own calibration device make it easy to regularly make or remake profiles: there's nothing to plug in, drop or fuss over.

Equipment Evaluators Amateur and Professional

DuckMany equipment testers fail to observe even the most basic principles. They snap some hand-held JPG images of ducks in a pond, share them at small size and pronounce the lens as "crazy sharp". They produce lengthy and opinionated videos with low-res image samples which provide no evidence to back up their recommendations. We should be careful not to make any purchasing decisions based on this superficial level of evaluation.

Lloyd Chamber's digilloyd is full of helpful information about a huge variety of cameras, lenses and other equipment. He provides sample shots taken at various apertures and sized to different resolutions. You can really see how equipment performs.

To test equipment properly, the camera should be fixed on a rigid tripod. The subject should be flat, stationary and unchanging, like a resolution target, a newspaper or distant scene. Lighting should be typical and unvarying. The camera should be set to its best ISO and in RAW format. Lenses should be manually focused at actual taking aperture (not wide open) to avoid focus-shift. Images should be examined with no sharpening or corrections and compared side-by-side at 100% magnification.

Resolution ChartProfessional equipment testers like LensRentals.com compare multiple samples of the same lens under controlled conditions. They measure center, middle and edge performance as well as de-centering, etc. They produce charts, not just snapshots.

Phillip Reeve doesn't produce charts but his tests are rigorous and the results are easy to discern. Another fine non-laboratory tester is Christopher Perez. For countless examples of thorough field-testing of lenses, see Fred Miranda. For example, see his FM Rolling Review: Sony FE 135mm f/1.8 GM.

Nasim Mansurov's Photography Life has a very good series of articles about lenses and their problems. Read What is Focus Shift? and others about de-centering, vignetting, curvature of field, etc. To put it all together, see How to Read MTF Charts.

How (and why) to Convert Images from 8 to 16 bit in Photoshop

Histograms At the left is the histogram of an 8 bit grayscale image file. Because of the shallow bit-depth, we can observe gaps in the tonal scale. This is also known as banding. As we continue to adjust the image, banding gets worse. The more corrections we make to 8 bit images, the more artificial they can look. For best image quality, we want to avoid banding.

If we simply change the file mode from 8 bit to 16 bit (Image > Mode > 16 Bits/Channel), Photoshop will not interpolate new values to provide intermediate tones as we perform adjustments.

Here's the trick: after converting to 16 bit depth, change the size of the image, even slightly. This will force Photoshop to interpolate all the pixels. As the histogram on the right demonstrates, the tonal scale is now smooth. Any subsequent adjustments to the tonal scale will be performed in 16 bit and no banding will be introduced. Smooth !

K-7 Carbon Pigment Prints: Tonality & Longevity

Go to Piezography Piezography K7 Carbon pigment prints are made with a graded set of pure carbon pigment instead of colored inks. They look beautiful and unlike ordinary inkjet prints will last as long as the paper holds together. These images are considerably more fade resistant than archival selenium-toned silver prints.

Unlike the color images we can make using OEM inks from Epson, Canon, HP - whose colors fade and drift at varying rates, depending on paper, lighting and storage conditions - carbon pigment prints do not fade appreciably.

To see how color inks fade and drift over time, see Aardenburg Imaging, an independent testing service.

Piezography Pro: Monochrome Printing Perfected

Go to Piezography Pro Piezography Pro is impressive: superb tonality, highest dMax, optimized gloss and matte options. Most important: the ability to combine neutral, warm and cool shades along the tonal scale. My favorite toning effect consists of warm shadows which smoothly transition to neutral high values: a linearized blended tone.

The Piezography inks sets consist of 6 or more graded inks made of pigment, not dye. Given that the ink is mainly Carbon-pigment-based, this method is considerably more archival than typical color inkjet printing.

For monochrome photography, Piezography Pro is Printing Nirvana. The results far exceed the tonal quality of typical printer inks (3 gray shades) and general-purpose profiles designed for making color photographs. Unlike profiles made with the open-source QTR tool set which are based on only 21 measurements, Piezography profiles are measured and linearized using 128 steps.

Piezography profiles are completely linear, with no banding, bumps or gaps in the tonal scale. Subtle tones in the shadows are not compressed to pure black. Highlight tones are not clipped to white.

To see what you are missing, print their Proof of Piezography target image. Using Piezography, all 128 steps are clearly delineated in even gradations and your printer delivers better image fidelity than most calibrated monitors (see The K7 Standard and Monitor Display Systems and related articles on the Piezography blog).

I previously used the MIS Eboni inks and relied on the Quadtone RIP documentation and forum. Compared to that approach, Piezography offers the following advantages:

  • Custom profiles available, linearized at 128 steps for your specific printer/paper combination
  • No clogging (pigment particles encapsulated in acrylic copolymer to eliminate electrostatic attraction)
  • A variety of ink color options like selenium, neutral, warm, cool
  • Tools for digital negatives for traditional wet and alternate processes
  • Everything works from end to end: you're not piecing together a collection of untested equipment
  • Superior ink, carts, syringes, packaging, instructional materials
  • Excellent customer support with fast turnaround time
  • Expert advice, web forums, blog, free instructional videos
  • On-site workshops for in-depth hands-on training
Printing MacOS Custom Sizes with Print Tool

Print Tool is a custom layout and printing application for MacOS with Epson and HP printers. It can run standalone or with a Quadtone RIP workflow. Print Tool supports JPG, TIF, PSD, PNG and GIF files in 8-bit or 16-bit RGB or Grayscale.

6 x 7.5 inch print on 8.5 x 10 inch paper

One of Print Tool's many compelling features is the ability to print on custom-sized paper with equal borders. This is vital because many of the standard paper sizes do not work with 8x10 and other traditional ratios. Unequal borders can easily spoil a composition: equal borders are a must !

Paper Size Image Ratio Image Size Cropped Paper Size Border Width
8.5 x 11 4 x 5 6 x 7.5 8.5 x 10 1.25
8 x 10 8.5 x 10.5 0.25
11 x 14 5.5 x 7 8.5 x 10 1.5
2 x 3 6 x 9 8 x 11 1.0
9 x 20 4.5 x 10 8 x 11 0.5
11 x 17 4 x 5 10 x 12.5 11 x 13.5 0.5
2 x 3 8 x 12 11 x 15 1.5
10 x 15 11 x 16 0.5
13 x 19 4 x 5 10 x 12.5 13 x 15.5 1.5
12 x 15 13 x 16 0.5
11 x 14 11 x 14 13 x 16 1.0
2 x 3 12 x 18 13 x 19 0.5
17 x 22 4 x 5 16 x 20 17 x 21 0.5
11 x 14 16.5 x 21 17 x 21.5 0.25
2 x 3 14 x 21 15 x 22 0.5
9 x 20 9 x 20 11 x 22 1.0

For example, I like to make proof prints on US letter paper (8.5 x 11 inch), with a 1.25 inch border. This comes out to a 6 x 7.5 inch print on 8.5 x 10 paper and is very easy to set up on Print Tool. This requires trimming our 8.5 x 11 inch paper to 10 inches long, as shown above. Another nice size is exactly 10 x 12.5 inches with a 1.5 inch border. We merely trim our 13 x 19 inch paper to 15.5 inches long, as shown below.

How to Tone Monochrome Images with Photoshop and GIMP

If you make monochrome prints using standard OEM inks, you can easily give them a "toned" appearance: the blacks are black, the whites are white - but the grays are varying shades of brown, gold, blue, violet, etc. Toned monochrome images often have a greater sense of depth than plain-old black and white. This is especially true of portraits.

Many of the great classic photographers toned their monochrome images in the darkroom and thus avoided the harsh and "gritty" quality of pure black and white. They printed with Platinum and Palladium or soaked their Silver prints in baths of Selenium, Gold, etc. Today using digital methods we can render a photograph with any tone we like, choosing the best color for each image.

With this method, every image can receive its own distinct toning with a 16-bit high-fidelity palette of shades. Read Photoshop Fill Layer for more information and learn how to do this yourself.

Attention GIMP Users: you can do the same thing with the GIMP Colorize tool. I prefer Photoshop but GIMP is free and runs on a wider variety of operating systems.

After reading these articles, please refer to Selective Toning with Photoshop and Selective Toning in the GIMP for improved methods.

Really Accurate Color Balance

XRite Color Checker Passport Photo 2 is a an affordable solution consisting of a portable target and software. It works with Photoshop and Lightroom to give you accurate color balance wherever you shoot.

The tool contains RGB and CMYK values, gray steps and other standard color patches. The newer Passport Photo 2 also contains an 18% gray card.

The test photo above was made under typical incandescent home office lighting and shows before and after profile correction. To watch a Youtube video about it, click here and see the X-Rite promotional video here.

Sony Mirrorless

Sony full-frame sensors deliver high resolution in a very portable package. The new 60MP Sony A7RIV full-frame sensor delivers 6,336 x 9,504 pixels: a 21x32 inch (50x75 cm) print at 300 dpi. (The older A7RII and A7RIII sensors deliver 5304 x 7952 pixels: an 18x27 inch print at 300 dpi).

The tonality and dynamic range are superb. At ISO 50 there is no apparent grain or sensor noise whatsoever, even at 100% magnification.

Sony A7RII, Voigtlander 75mm f/2.5 Color-Heliar

To get resolution like this across the entire image, we need to shoot lenses at their best aperture and keep the camera very steady. The larger the print, the more important this becomes.

Dynamic Range - A7RII

This A7RII photo was underexposed dramatically at ISO 100. The shadows appear hopelessly dark. Using Adobe Camera Raw we have lightened the dark values. The A7RII sensor can accommodate a substantial range of brightness from outdoors to indoors. Newer models like RIII and RIV do even better.

Compressed vs. Uncompressed RAW

Shooting the above photo, two exposures were made: one an 82MB RAW file, the other a 41MB Compressed RAW file. They were exported from Adobe Camera Raw with identical (synchronized) sharpening, noise reduction and monochrome conversion. Is there a visible difference ?

Here are 100% crops from the photos above. On a typical monitor at around 110 dpi, the full image would be roughly 50x75 inches (120x180 cm). Even at 100% magnification, the difference between these two versions is so small that a slight change in sharpening and noise reduction can hide any distinction whatsoever.

These drastically underexposed shadow areas were rescued in post-processing. How much of a difference can we expect in a properly exposed photograph ? If we need to save on storage, the Compressed Raw option is very attractive.

For an in-depth analysis, see this review by Jim Kasson. According to his test results, with compression enabled at ISO 100 image bit depth drops from 14 to 13 bits. With compression enabled, bit-depth keeps dropping as we increase ISO. At what point this becomes noticeable to you, is for you to decide, based on your choice of subject, lighting and ISO. At high ISO you should notice the most artifacts and noise.

Sony E-Mount Cameras: Latest News

To keep up with the latest news and discussion about Sony E-Mount cameras and equipment see Sony Alpha Rumors and Fred Miranda's Sony Forum. An official Sony shooter, Brian Smith's blog is highly informatve.

Brian Smith's Ultimate Guide to Fullframe E-Mount FE Lenses is comprehensive and regularly updated.

Although less frequently updated, here's another survey and evaluation of native full-frame lenses with electronic coupling for Sony E-Mount cameras by Phillip Reeve: Sony FE Lenses: a Comprehensive and Independent Guide. He also provides these additional helpful articles: The Best Lenses Below $499 for the Sony A7 Series and Beginner’s Guide to Manual Lenses on the Sony A7.

For news about digital equipment of all stripes, see Digital Photography Review.

 Auto  Manual Focus Please

For fine-art subjects (as opposed to snapshots, sports, wedding and fashion), manual focusing is preferable. We're rarely working quickly and we can't trust the camera to make the right artistic decision. For example, see below where sharp focus has been applied off-center.

Sony A7RII, Nikon 55mm f/2.8 Micro-Nikkor

Because the Sony provides focus-peaking and magnification, it's like using a loupe on a view camera. Mirrorless cameras provide a level of precise focus that can never be reached while looking through an SLR or rangefinder window.

Another advantage of manual focus: we can focus with the lens stopped down to the actual taking aperture. This not only helps us preview depth of field, it eliminates focus shift.

Affordable Adapted Lenses for Sony

Sony mirrorless cameras have a very small flange-to-focus distance, allowing us to adapt a wide variety of 3rd party lenses such as Leica, Nikon, Canon, Pentax, Voigtlander, etc. To shoot manual lenses, a simple affordable adapter is all that we need. I was disappointed with a no-name bargain adapter (it developed a light leak which resulted in flare), but have had good experience with Fotodiox Sony E-Mount adapters.

For fine art subjects (landscape, still-life, portraits), older lenses are often an excellent choice. Many perform just as well as the newest ones, the only difference being that they are manual focus and have no built-in stabilization. Available in the used market, they are affordably priced.

55mm f/2.8 AIS Micro-Nikkor

There are countless lenses available in the normal focal length but for its combination of image quality, flexibility and low price I chose the 55mm f/2.8 AIS Micro Nikkor from 1979. You can buy this lens used on eBay or from KEH but after decades it is still available for purchase new because it's a fine performer even by modern standards.

It focuses down to 1:2 but is very sharp at all distances due to what Nikon calls Close Range Correction: a floating internal element. At its closest magnification of 0.5X, it's close to the top of the heap on the coinimaging.com Hall of Fame

With this model, no lens shade is required because the optics are recessed within the barrel. Because this lens does not open wide it is light and portable, taking 52mm filters like many other Nikon designs. I love macro lenses: they are usually free from chromatic aberration and geometric distortion. Many standard lenses are sharp but if you like to shoot at close distance without needing an adapter and you appreciate not needing a lens hood or corrections in post-processing, this is a fine choice.

For a collection of images made with the 55m f/2.8 Micro Nikkor, click here.

Voigtlander 75mm Color-Heliar f/2.5

The Voigtlander 75mm Color-Heliar f/2.5 was introduced in 1999 and the Leica screw-mount version is portable, affordable and sharp with a 10-bladed aperture and excellent blur rendition. Although not officially a macro lens, it performs very nicely at close range using a stretch adapter or extension tubes. There is a very slight pincushion distortion which is easily addressed by the Adobe Camera Raw profile for this lens.

The lens shade is integrated into the design and the lens cap fits over the shade, making it even more portable in actual use. Weighing only 230g, it takes 43mm filters and is only 65mm long: less than the filter size of many modern designs. Even with the lens hood in place and an adapter attached, this lens fits in your pocket ! You can carry it for long periods of time.

Perhaps the weakest point of this lens is purple fringing under situations of extreme contrast, which can be corrected in an editing tool. It's not a perfect lens by modern standards but it's highly useable in most situations.

There are faster lenses in this focal length, but I prefer lenses which do not open very wide: they are smaller, lighter, more affordable and optically superior. Lenses which open wide often have mediocre performance at wide settings, particularly away from the center of the image. If not, they are prohibitively expensive, large and heavy.

For a collection of images made with the 75m f/2.5 Color Heliar, click here.

135mm f/3.5 Nikkor AI-S

The 135mm f/3.5 Nikkor AI-S is a manual focus prime lens made from 1977 to 1981 and has minimal distoration, excellent optics and a built-in lens hood. Only 81mm long, it takes 52mm filters. It's very portable - and very affordable - when compared to modern offerings. If we shoot stationary subjects and use a tripod or high shutter speed we rarely need autofocus or image stabilization... especially at 1/20 the price !

Photographer and lens-tester Christopher Perez writes "I think the Nikon Nikkor 135mm f/3.5 AI-S should become my 135mm "control" lens. It is the standard by which I could measure all other 135mm lenses."

For a collection of images made with the 135mm f3.5 Nikkor AI-S, click here.

200mm f/4 Nikkor AI-S

Like the 135mm f/3.5, the 200mm f/4 Nikkor AI-S is a manual focus prime lens with minimal distortion and excellent optics. It was built from 1981 to 1996 and has a built-in telecoping lens hood. I love telecoping lens hoods !

Because it opens to a maximum aperture of f/4 it can take standard 52mm filters and is a very portable and affordable alternative to modern offerings. In situations of high local contrast, it can exhibit some color fringing but that is easily corrected.

For a collection of images made with the 200mm f/4 Nikkor AI-S, click here.

35-105mm Zoom Nikkor Macro

The 35-105mm Zoom Nikkor Macro was introduced in 1983 and is available at modest price in the used market. A manual focus zoom, it opens no wider than f/3.5 so it's compact, taking 52mm filters like the 55mm Micro Nikkor and many other Nikkor designs.

At 105mm this lens has extremely neutral blur rendition and is quite sharp at all distances. It can be used in place of a 105mm prime lens.

On a full-frame sensor, stopping down to f/8 or greater improves corner performance considerably. Click here twice for a full-size sample image shot at 105mm: 4x6 feet on typical web browser.

At widest apertures, if we're looking for the highest corner resolution this lens is better suited to APS-C format or close focus, where we use only the central portion of the image circle.

This lens has 16 elements in 12 groups and a ring which shifts the internal arrangement, allowing you to gradually transition to macro mode. At the 35mm setting, it can focus down to a 1:4 ratio. If we add a short extension tube the lens will focus very closely at all focal lengths.

70-300mm Nikkor AF ED

The 70-300mm Nikkor AF ED is very affordable and portable compared to similar offerings. This model provides autofocus on Nikon cameras, but no image stabilization. I use a simple Fotodiox Nikon-to-Sony adapter which does not provide autofocus.

Stopping down to f/8 or greater improves corner performance considerably. At widest apertures, if we're looking for the highest corner resolution this lens is better suited to APS-C format or close focus, where we use only the central portion of the image circle.

To get higher resolution or built-in image stabilization, professionals who make very large prints may require a better lens - at much higher cost - but if we shoot at best aperture, print at reasonable size and avoid the corners of the sensor, this lens offers long reach and light weight at an attractive price-point.

Traditional Aspect Ratio on Full-Frame Sensors

We can crop a full-frame 24x36mm digital sensor to the 4x5 ratio and make prints at 8x10, 11x14, 16x20 etc. The sensor becomes 24x30mm. Reducing the horizontal dimension by 20%, all lenses give a 20% greater effective magnification. For example, a 42mm lens on this cropped full-frame format functions like a 50mm "standard" lens... etc.

4x5 Ratio

Portrait Focal Length

Modern portrait shooters often select lenses in the range of 85mm to 135mm to isolate the subject against a blurred background. This works well for head shots in a commercial setting where images are viewed only briefly and must compete for attention. However, portraits made from a distance can feel impersonal and flat.

Traditional portraits were made from a closer distance and usually included more of the subject. The formula to determine focal length for traditional portraits was film height plus width. For example, a 9-inch lens was favored on 4x5 inch film since 4+5 = 9 inches. Lenses from 200 to 240mm roughly match this formula.

For traditional portrait lenses, the horizontal angle of view is approximately 30 degrees. For an online tool which lets you easily calculate angle of view for any sensor of film size, see Rui Salgueiro's field-of-view calculator.

On a 24x30mm sensor, 24+30 = 54 so 55mm lenses work nicely. (On a full-frame 24x36mm sensor, a 65mm lens gives a 30 degree horizontal angle of view. On APS-C, a 45mm lens does the same.) This viewing angle conveys a heightened but natural sense of intimacy and depth, not only for portraits but for most subjects. When cropping to a 24x30mm sensor, I use a 55mm lens for almost all of my photographs, but the actual range spans 50mm to 60mm.

Fortunately, lenses in this range are generally the best performers ! Cropping to the traditional format further improves image quality because we discard the corners of the image at the extremes of lens coverage where resolution is weakest. Working in the traditional aspect ratios, our lenses get a free performance upgrade !

Step-Up Rings

Don't purchase a set of filters for every "odd-ball" size (and carry them into the field). An inexpensive step-up ring can save you money, space and weight. If you add a step-up adpater ring to your smaller lenses, they will take a larger lens cap and you can purchase a single set of filters.

Favorite Tripod and Heads

Bogen 3021 BN Pro This tripod is neither the largest, smallest, heaviest or lightest - but the Bogen 3021 BN Pro is an affordable all-around solution. It's built strong enough and light enough. It's not made of carbon fiber but unless you are a trekker... who cares !

Sorry, I do not recommend ball heads: when we adjust the camera in one direction, we lose the other two planes of orientation. Ball heads are hit-and-miss. They drift as we tighten the knob, due to the weight of the camera. For precise work, they are practically useless ! I recommend geared tripod heads for general use. For careful positioning of small cameras at close distance, I recommend a 4-way Focusing Rail.

Bogen 3275 410I like the Manfrotto 3275 410 geared tripod head, which is rated for holding cameras up to 11 pounds. It lets you make fine adjustments in 3 directions, independently. It's small, light and strong. It's a treat to make adjustments this way: there is no drift. I use it with cameras that are comparatively light in weight, like wooden field cameras and digital cameras.

Geared movements let us make minute compositional adjustments, critical when shooting small objects at close distance, like these Tulip and Telephone photographs which were made with a Sony mirrorless camera. There are better geared tripod heads on the market like the Arca Swiss C1 and D4, but the Manfrotto is considerably more affordable.

Manfrotto 229For heavier equipment, consider the Manfrotto 229 tripod head. It's rated up to 16 pounds and has no problem holding a Sinar P with 5x7 back, extension rails etc.

Here's a cold-weather tip: wrap some pipe insulation around the legs and hold it down with some inexpensive duct tape. This will keep your hands warm when you carry the tripod. Pipe insulation is very inexpensive but you will find this very helpful in winter time. It also helps if you want to carry the tripod on your shoulders: it's soft on the body.

Favorite Tripod & Head for Travel with a Small Camera

The Oben CT-3535 Folding Carbon Fiber Travel Tripod with BE-208T Ball Head folds to only 12 inches and weighs only 2.5 pounds. It fits in just about any backpack or shoulder bag and is therefore ideal for travel. It also converts to a monopod and comes with a ball-head that will orient vertically. Ball heads are suitable for travel when weight and size must be kept to an absolute minimum.

You can watch a Youtube video about this tripod here.

I use this combination when traveling with my Sony A7RII. When possible I replace the Oben ball head with the Manfrotto 3725 410 head shown above. Even though it weighs as much as the tripod, it is finely geared.

Leveling Base - What a Relief!

Manfrotto 438 Manfrotto 438A leveling tripod base like the Manfrotto 438 sits just below the tripod head (see yellow arrow). You get a level platform without having to adjust the legs of your tripod. This piece of equipment doesn't weigh very much but makes life much easier - especially when shooting in the field, where the ground is rarely level.

On the right you can see the leveling base in action. The tripod is not level - as the red line shows - but the tripod head is level, because we have adjusted the leveling base beneath it.

With such an arrangement, we can pan the head horizontally (or move the 3 gears of the 410 head in any direction we like) and we don't have to correct anything afterwards. To adjust the leveling base, just loosen the lever and use the bubble level. It's much faster than changing the length of the tripod legs. If you've ever tried to work with a tripod that isn't level, you'll appreciate this improvement !

Printing Accurate Colors

Atkinson Test Image At right is an image which can tell you if your monitor and printer are reasonably color-calibrated and profiled. Click on it to see it full-sized. You should be able to see all the shades of all the colors. Can you see the purple rocks in the fish bowl ? Is there plenty of detail in the shadows of the sand dunes ?

Now print these images on your printer and see if the final results looks like what you see on your monitor. Ideally, they should match, very closely. If they don't match, then perhaps your monitor is off or your printer needs to be profiled... Probably both !

Ideally, we should have our own custom profile for every combination of printer/paper/ink that we use. The same ink has a unique response to every different kind of paper - and every printer is unique. They are mechanical devices, subject to variation. Just like musical instruments, they need to be tuned up, all the time.

Printer manufacturers like Epson now make profiles for their own printers/inks/papers freely available for download and tools like Photoshop allow you to print your images with the profile of your choice. These are not as good as getting your own profile but they're a great place to start and you can't beat the price ! It's hard to get things right, even with all the right tools. Without a calibrated workflow, it's almost impossible !

For best results with color printing, get someone like CHROMiX to make profiles for you. If you only print with one paper, you only have to get one profile made when you get a new printer. If you're printing black and white exclusively, use Piezography. If you don't want to have a custom profile made, then at least get one of the profiles from the public domain. Thanks to InkJetArt.com for the test image, which comes from Bill Atkinson.

My Prints are Too Dark My Monitor is Too Bright

Color Wiki Even if your monitor has been recently calibrated and you are printing with a custom profile for your printer/paper/ink, you may still end up struggling to match your prints to what you see on your monitor. Why? Because LCD monitors are much brighter than paper and manufacturers are making monitors brighter with each new generation. When editing photos to be printed, we need to work at the brightness level of paper.

If you have a light meter, you can see for yourself that bright office illumination is such that a white piece of paper, or a white wall, gives an Exposure Value or EV, around 9. Actually, EV 9.3 is around 80 cd/m2, so that's good level for digital printing if your photos will appear in a brightly lit office or gallery. Many homes (and some galleries) are darker than that, more like EV 8, 7, or 6 or lower. We need to lower the brightness of our monitor to match the brightness level of our intended display area.

If you don't have a light meter you can use one of the many phone apps, like Luxi. Be sure to use the value for ISO 100, since that is the standard.

Typical LCD monitors don't do well at these levels: they are designed to be brighter than standard office walls. That's why print imaging specialists don't use consumer grade equipment. Instead they use monitors like Eizo and NEC SpectraView, which are designed to perform at paper brightness.

Here's a superb video presentation from Andrew Rodney: Why Are My Prints Too Dark ?. Here's a nice article on the Shutterbug web site, entitled Are Your Prints Too Dark ? Here's another one, by Pat Herold of CHROMiX. It's called My Printer Is Too Dark on the CHROMiX Color Wiki.

"If you do not set up your system so the white of the paper and the white of the monitor are as close as possible, you will not get a good screen-to-print match." - Pat Herold of CHROMiX
OBAs and Metamerism: Bright Papers and Color Shift

Metamerism In order to make Inkjet photo papers look whiter, manufacturers not only bleach them, they add OBAs: Optical Brightening Agents. Brighteners are commonly added to laundry detergents to make white clothing appear cleaner and brighter. When exposed to daylight (which contains UV light), the OBAs luminesce. They emit blue-white light. The brighter the whites, the deeper the blacks look by comparison. It sounds great, no ?

The problem is that under indoor lighting, they don't luminesce, so your images look dull. With less blue, the same image suddenly looks pink. This effect is known as metamerism, or color shift: your print looks different, depending on where you view it. While harmless for family snapshots, it's unacceptable for Fine Art prints. Traditional Silver-based photographs don't suffer from Metamerism - and neither should a good inkjet print.

To make matters worse, OBAs fade over time. Even if the image looked right under daylight, it starts to look wrong eventually. The print you spent so much effort to make, is slowly replaced, so to speak, with something else.

Not all papers have OBAs: some are made with 100% Cotton Rag, have no OBAs and exhibit no color shift. Two papers I recommend are Epson Hot Press Natural and Premier Smooth Hot Press. Another brand I really like is Canson Infinity Museum Quality 100% Rag papers. Be sure to look for papers which have no OBA's. Canson writes "No Optical Brighteners" right on the front of the box. I like their Rag Photographique: it's very smooth, 100% Rag, has no OBAs and a great color.

To see how different papers and inks fade and change over time, see Aardenburg Imaging. Mark McCormick-Goodhart is a first-rate scientist and a world class expert in the field of image permanence.

Favorite Backup Software for Mac

Carbon Copy Cloner

Apple's Time Machine is great for backing up your computer, but it's safest to keep your images and other important documents on a separate drive.

Carbon Copy Cloner lets you schedule tasks to back up your files - from one disk to another - as many disks as you like - as often as you like. Back up all your files, or copy only what has changed. Move a copy of your digital files to a backup disk. Back up your OS X system files to another disk. Copy your large Photoshop files to another disk. I schedule these tasks to run in the middle of the night, while I'm sleeping.

Large Format Cameras, Lenses, Film, Darkroom, Scanning etc.

Shooting in Massachusetts with a 4x5 Sinar P

Sinar PSinar Yaw-Free Movements The Sinar P view camera: P stands for Perfection. The Sinar is what all the other view cameras would be... if they could. You can easily locate one on eBay, where there's an abundant supply of used Sinar equipment.

Everything is geared. Every adjustment is smooth and silky. There are very few locking mechanisms, since the gears are so well made, they just stay where you leave them. Made in Switzerland.

The Sinar has asymmetric or yaw-free movements. It stays in focus when you tilt, swing, rise and shift. With other view cameras, you have to tilt, refocus, then raise or lower the camera - over and over again. With the Sinar, you just focus and dial-in the adjustments until everything is right. It's heavenly !

The Sinar is a modular system camera. If you want to add or replace things, you can. Turn your 4x5 camera into a 5x7 or 8x10 camera ? No problem. Just replace the bellows and the back. Search for a conversion kit, also called format change set, conversion set, etc). The kits are smaller, lighter and cheaper than cameras. Because Sinar is/was the workhorse of choice for so many professionals, there is usually plenty of used equipment to choose from, in excellent condition. Igor's Camera Exchange carries a lot of Sinar equipment and expertise.

Kodak 2D Another superb camera is the 5x7 Kodak 2D, a wooden field camera (left). I found mine at an auction and had a new bellows put on. It works fine again. On the left you can see what someone else's fully restored 2D looks like. It's the latest in 1920's technology !

The 5x7 Kodak's light weight and folding design makes it great for carrying around. Unlike most folding cameras, the Kodak hybrid design lets you leave a lens on the camera at all times, which makes things easy and fast when setting up.

TachiharaWhen maximum portability is required, consider the 4x5 Tachihara Wooden Field Camera (right). It's very light and folds quite small. With its red bellows and brass fittings, it attracts curiosity and draws onlookers like a magnet. Using a 200mm Nikkor M lens, it's a treat to walk around and shoot a wide variety of subjects. You can save time and economize space by leaving the lens on the camera, reversed.

If you would like to see what some other Large Format cameras look like, have a look at this thread entitled Show Off Your Camera on the Large Format Photography Forum. You may be surprised to see how many people use them - and how many different kinds of Large Format cameras exist.

View Camera Movements: the Real Deal

Ordinary cameras have lenses that are mounted straight ahead, so they look straight ahead only. That's fine for many subjects but view cameras let us adjust the plane of focus at the front and rear of the camera. We can focus along a complex plane and make photos that are either impossible or arduous with ordinary cameras.

Click here to see some photos that were made using view camera movements. Some of these adjustments can be created after image capture with editing tools but not all. View cameras allow us to explore and combine adjustments creatively, while composing the image: something quite different from repairing mistakes in post-processing.

With focus-stacking, depth of field can be simulated but not necessarily along an oblique plane. Tilt/shift lenses are available in limited focal lengths for Canon and Nikon cameras. Tilt/shift adapters let us adapt lenses designed for larger sensors or film, but to get more extensive (but limited) view camera functionality with a digital camera, see the Cambo Actus and the Arca Swiss Universalis.

Some Favorite Large Format Lenses

For a discussion of some favorite lenses for Large Format cameras, click here. We discuss vintage and barrel-mounted designs, portrait lenses, modern lenses for use in the field - as well as macro and process lenses, the Sinar Copal Shutter and a blur rendition or bokeh and a 4-way bokeh comparison of vintage and modern designs.

Included are sample image galleries for Rodenstock APO Sironar-S, Rodenstock Macro Sironar, Voigtlander Braunschweig Heliar, Carl Zeiss Jena Tessar, Fujinon A, Fujinon C, Fujinon T, Fujinon SFS, Nikkor M, APO Nikkor and more. You can see that differences between them are often... exaggerated.

Sample Large Format Images

8x10 Here is a family portrait sized at 32x40 inches, made from a 4x5 negative.

Here is a photo made with a 1930's Kodak 2D: the detail available from a 5x7 negative is impressive. An 11x14 print is barely a 2x enlargement !

Of course, 5x7 still falls short of 8x10: here's an 8x10 sample image with detail section - made with an 8x10 wooden field camera. It puts the smaller formats to shame.

Scanning Tips (with EPSON and VueScan Software)

Go to Scanning TipsHere is a brief tutorial on Scanning Tips with Epson flatbed scanners but it applies to any scanner we use.

To make a digital image which looks as analog as possible - as smooth as possible - we need to work around some of the default settings provided by the scanning software.

With my consumer-grade Epson flatbed scanners, the green channel is slightly sharper than the red and blue channels. Read Scanning the Green Channel for Optimum Resolution to learn more.

Formulas for Bellows Extension

A 150mm lens needs 150mm of bellows draw - at infinity. As we focus closer, more bellows extension is required and more exposure is required. How much more ? For perfect exposure, we want to know. For a lens of given focal length and bellows with a specific maximum extension, how close can we get to the subject ?

If we want a certain degree of magnification (say 1:3) and we know the focal length of the lens, how much bellows extension do we need ? With a lens of given focal length and a bellows of known maximum extension, how much magnification can we get ? At 1:1 magnification, a 150mm lens requires 300mm of bellows extension. How do we compensate for exposure as bellows extension increases ?

Click here for a page which provides formulas for bellows extension.

Reciprocity Timer app

If you don't care to memorize the formulas for bellows extension and film reciprocity, consider this wonderful application for the iPhone: Reciprocity Timer by Pump Interactive. It really works !

Favorite Monochrome Sheet Films

Film You will love Kodak TMAX 100, TMAX 400 and Ilford FP4+ and HP5+ films. These films have long straight response curves, which means they give realistic detail throughout the tonal scale. They also have a very linear response to changes in development time, which makes them easy to use in both high and low contrast lighting. If you are familiar with the Zone System, this means that they are easy to "expand" and "contract" with changes in development. Ilford offers their film in a wider variety of sizes than Kodak and at lower prices too.

Tabular grain films like Kodak TMax and Ilford Delta have grain that is flat, or tabular - rather than round. The result is a cost savings for the manufacturer, because a thinner layer of Silver is required. Tabular films require more sensitizing dye and thus require longer washing times to remove the dye. Traditional films like Tri-X, Ilford FP4+ and HP5+ need less washing, because there is less dye to remove.

Very Simple Film Developer: D-23

The formula for D-23 developer has only 2 ingredients but produces clean negatives with fine grain, excellent tonal separation and good film speed. It's so simple, you can mix it fresh every time. There's no need for a stock solution - nothing to expire on the shelf and surprise you. Click here for additional photographs and more information about D-23 .

Ansel Adam's classic image "Winter Sunrise from Lone Pine, 1944" was developed in D-23. See Examples: The Making of 40 Photographs page 164 to read more about his lovely photograph.

D-23 is a one-bath developer. It is not the same as Divided D-23 which is a 2-bath formula. Divided D-23 is also known as DD-23. Are you looking for Divided D-23 ? See this article.

Odorless Stop Bath: Citric Acid

You can make your own Odorless Stop Bath using Citric Acid. The Kodak SB-8 formula calls for 15 grams per liter, or 1/2 oz per quart. Or you can also use plain water for stop bath if you like. Using an acid stop bath, development is stopped instantaneously. Using water, it is stopped also, just not as abruptly. You can use a weak solution of Citric Acid: 1 teaspoon per liter. Citric Acid is very cheap, harmless and... odorless. In the USA, a good source for materials is Artcraft Chemicals.

Favorite Fixer: Alkaline

Ingredient Stock Working
Ammonium Thiosulfite 800 ml 160 ml
Sodium Sulfite 60 g 12 g
Sodium Metaborate 5 g 1 g
Water to make 1 liter 1 liter
You can mix your own Fixer, using the traditional T-3 Alkaline Fixer formula. It has only 3 ingredients! Alkaline fixers require much less time to remove via washing and do not require a washing aid. They have much less odor too !

(If you use a Hypo-based fixer, you can easily make your own washing aid: just use a teaspoon of Sodium Sulfite per liter of water and toss it when you are done.)

According to Anchell and Troop, in The Film Developing Cookbook, Alkaline Fixers have the following advantages over more traditional Acidic formulas:

  1. Less danger of over-fixing
  2. Shorter washing times
  3. More archival
  4. Greater capacity
  5. More stable
  6. Can be formulated to have low odor.

The T-3 Alkaline Fixer formula is intended to be diluted 1+4. Instead of making stock, you can make a working solution by dividing the amounts by 5 (see table above).

It's fun - and far less expensive - to mix your own chemistry. Many of the classic formulas are available in books and on-line at sites like Jack's Photographic and Chemistry Site. In the USA, a good source for materials is Artcraft Chemicals.

Removing Magenta Stain from Kodak TMAX Films

Kodak adds a magenta sensitizing dye to its TMAX films. Depending on your water and other factors, that dye can be hard to remove with ordinary fixing and washing. Do not prolong the time in the fixer: that will not remove the stain. Instead, rinse your negatives briefly in water after fixing, then soak them in a 1% solution of Sodium Sulfite for around 10 minutes (1 teaspoon per liter of water). Then rinse and wash normally.

Sodium Sulfite is the active ingredient in Film and Paper Washing Aid: if you use an acid fixer, you will need that anyway. If you use an alkaline fixer a washing aid is not required but a soak in Sodium Sulfite will remove the magenta stain if necessary. In the USA, a good source for materials is Artcraft Chemicals.

Affordable Equipment for Film Development and Washing

Dish Rack Film Washer Storage Container Developing Trays Some people purchase expensive custom equipment to wash their film. Nowadays, you can construct your own washer out of inexpensive and widely available materials.

A Dish Rack Film Washer costs only a few dollars. Your film just soaks, in a bunch of standing water. There is no need for a fancy syphon or drain system: Just let the film soak and replace the water now and then. Save the water and let diffusion do the work for you. You can use a similar technique to wash roll film too.

Photo trays are great for developing prints but you can do things better - and cheaper - with items available almost anywhere. Plastic Food Containers are more affordable, use less chemistry, prevent scratches and require less room. Once you try them, you will wonder why you ever used traditional "Photo Trays".

Infra-Red Monocular: Seeing in the Darkroom

ATN Viper Once you start using something like this ATN Viper Night Vision Monocular, you will have a wonderful time developing, loading and unloading black and white film in the dark. You can see everything, without fogging the film. If you're cramped into a small space, there's no chance of knocking things over.

You can perform Development by Inspection (DBI), not in the old fashioned way (where you get only a brief peek under a dim green bulb) but throughout the entire process: development, stop bath, fix, etc. You can do tray development with ease, with far fewer scratches and with greater confidence that things are turning out right. This tool pays for itself - the first time you use it !

Important Note: As development proceeds, the film looks darker and darker. If you examine only the emulsion side, you will get the erroneous impression that development has proceeded too far, too quickly. To determine development, do not judge the emulsion side. Examine the shiny side of the film. Be sure to practice before risking any important work and use your darkroom timer too.

There are many kinds of Infra Red Night Vision viewing devices and this one is simple and affordable. If you can't see the ATN Viper on the Optics Plus web site, try this eBay search.

How to Avoid Fingerprints on Sheet and Roll Film

If you handle film, make sure to keep your finger tips clean. It's easy and affordable to clean them with a bit of Isopropyl Rubbing Alcohol on a clean cloth or paper towel. Clean your fingertips before loading sheet film. Clean them before unloading and developing. Clean them before hanging film to try. Clean them before scanning film. You'll be glad you did !

Affordable Scanner for Large Format

Epson V850 You can scan your negatives with an affordable flatbed scanner like the Epson V850 and the Epson drivers which ship with the scanner. A 4x5 inch negative, scanned at 2400 dpi (samples per inch), gives a 115 megapixel image. A 5x7 inch negative, scanned at the same resolution, gives a 200 megapixel file. Is that enough ?

At such high resolution, image fidelity is very good and the tones are... rich ! Tiny JPG files, viewed on the monitor, just can't convey the feeling. An 11x14 image made from one of these negatives is truly lovely.

Carry Your Gear on a Budget

GearSome photographers buy expensive cases and packs to carry their gear. I prefer a canvas bag and a beverage cooler. The Sinar P folds down small enough to go into the bag, upside down. The Sinar is built like a tank. The only thing it needs, is a carrying strap and that's what the bag is for. Everything else goes into the cooler, which has a nice sturdy strap to go over your shoulder.

The beverage cooler keeps the equipment cool in summer and warm in winter... How does it know ? Even more importantly, it looks like a beverage cooler, to anyone who might see it in the car. Some people like to flaunt the name of their camera, as a status symbol. I prefer the safety of my gear looking like nothing more than a case of soft-drinks.

Note the pipe insulation on the tripod legs, held on with duct tape. Pipe insulation is very light in terms of additional weight but vital when shooting in cold weather: it can keep your hands from freezing when you carry the tripod !

iPhone Shutter Speed App

Try this affordable and helpful Shutter Speed app for the iPhone. It listens to your mechanical shutter and measures the actual speed. It may not be as accurate as the (now discontinued) Calumet Shutter Tester mentioned below but it's accurate enough. If you want to purchase an add-on light sensor, it will give you very accurate results.

I tested my old #4 Alphax Shutter with this app. The shutter is very close to its old-fashioned speeds of 1/2, 1/5, 1/10 etc. That's good to know !

Calumet Shutter Tester Brochure

Thanks to Boston-based Architectural Photographer Peter Lewitt, you can see the manual for the Fidelity Calumet Digital Shutter Tester, which is no longer offered by Calumet Photo. The Shutter Tester allows you to test the shutters on a variety of cameras and lenses. Even though it is no longer sold, you can click here to read the manual. Perhaps you can purchase one on the used market.

If you like to control the visual quality of your photos and you acquire equipment from others, it's nice to know how close it is to the correct speed.

Polarizer + Yellow Filter for a Natural-Looking Scene

Corn FieldWhen shooting black and white film, it's common wisdom to use a red or orange filter to darken the sky and clear the haze. For certain subjects this works very nicely but red and orange filters not only remove blue light from the sky: they also darken the blue light in shadows and the green light in vegetation.

To avoid ink-black shadows and unnaturally dark vegetation, we can use a polarizer along with a yellow filter if required. Rotating a polarizer, we can control the amount of darkening in the sky according to taste, while maintaining a normal balance of colors in the rest of the scene. If we need even more richness in the sky and clouds, we can reach for a medium yellow or light orange filter and place it on top of the polarizer. That's how this image was made (on 8x10 film). Note the tones in the grass and the trees: the yellow filter has actually enhanced the details in the vegetation, not darkened them.
