Previewing Black-and-White Conversions

By David Saffir

Deep down, I’m in love with the look and feel of black-and-white prints. When I was 11 years old or so, I dove into photography in a big way. And because it was less expensive, black-and-white was my medium of choice.

The wonder of watching prints magically appear in the darkroom has never left me. I still experience many of the same feelings when watching a print I’ve worked on come off the inkjet printer. Perhaps it’s a bit less mysterious, but it’s always a thrill.

So now the puzzle: What’s the best way to make high-quality black-and-white images using digital technology? I’ve tried using the presets offered in some cameras, but the trade-offs in image quality are even worse than the ones involved in shooting JPEG instead of the RAW format. It just dumps too much image information to be really useful.

That means the best choice is to shoot in color, and convert the image to black and white later.

What’s the best way to do this?

One way is to use image-editing software such as Adobe® Photoshop® Lightroom®. Lightroom comes with a number of presets that let you replicate traditional darkroom processes for toning, contrast, and special effects. These presets are remarkably easy, quick, and fun to use. And the previews are a snap! Simply roll your mouse pointer over the preset, and voila! The thumbnail shows you a preview (Fig. 1).

If the range of presets that Adobe provides isn’t sufficient, you can download other presets that have been created by individual photographers.

Or, you can try some of the conversion presets included with the black-and-white adjustment layer in Adobe Photoshop CS3. These presets are very useful, and many correspond to film-based techniques (i.e., they simulate the use of a colored filter to increase contrast, etc.)

One thing that has always troubled me when testing options for black-and-white conversions is the “before and after” issue. What’s the best way to visually compare the converted image to your original?

I’ve tried using duplicate windows, layer comps, and other techniques, but the pace was too slow. Recently I came up with another idea (which may not be new to many of you). The method is illustrated in Fig. 2, and involves six steps in Photoshop CS3.

  • Make a selection in the image.
  • Create an adjustment layer from the selection.
  • Experiment with different conversion settings.

Working this way lets you see the changes side-by-side with the original, in real time. I have found that I prefer this method over other viewing options in Photoshop. And the new dialog box in CS3 includes six channels, up from three available in the Channel Mixer dialog.

  • Save the combined settings you’ve developed as a preset by clicking on the tool in the Photoshop dialog box in Fig. 3.
  • Delete the partial adjustment layer.
  • Create a new adjustment layer, and load your saved preset.

Your image is now a custom-tuned black-and-white masterpiece!
