Photos with strong graphic qualities tend to lend themselves well to black and white. When I say ‘graphic,’ I’m referring to the lines and shapes in a photo. For instance, take a look at the photo above. It’s the entry to the Sofitel Hotel in downtown Chicago. The abstract shapes catch my eye as strongly if not more strongly than the literal objects in the photo. Black and white helps to disconnect the literal and abstract qualities of a photo, emphasizing the abstract shapes and lines within the frame.

In addition to highlighting the abstract qualities of a photo, black and white can also focus the eye on textures within the photo. The photo of this tree illustrates a little of both concepts to me. I was interested in both the shape of the tree (weird huh?) and also the texture of the bark. In color, the textures just didn’t have the same impact. The difference between the light and shadow areas of the bark would have blended a bit more since the color gradations would have hidden some of the contrast. But in black and white, I can almost imagine what it would have felt like to run my hand over the deep wrinkles across the bard of this old tree.

Sometimes black and white is best because the natural color in a photo is awful. For instance, I took this photo on a bright sunny day in Florida over the summer. The dolphins worked it out right alongside the boat for a solid five minutes. The downside? The water was a sickly shade of green. While this photo isn't truly black and white (it's dual toned - that's another post down the road), it illustrates the concept. There are a variety of ways to deal with weird colors in a photo (adjust the white balance or use off-camera flash to control the ambient lighting, among others), and black and white is just one tool in your toolkit. In this case, it happened to be the best tool.
If you haven’t noticed by now, I’ve referred to black and white as a tool quite a few times. Take note, however, that I have not said anything about rules or even guidelines. For me, photography is about playing and learning, not so much about rules. But here’s one guideline: Even if you know that a photo is going to be in black and white, shoot it in color. When you have a photo in color, you can do much more to manipulate the final black and white image. For instance, changing the white balance of a photo can significantly change the feel of the photo in black and white. Also, make sure to play around with the contrast, increasing and decreasing contrast makes a big difference in a black and white image. I use Adobe Lightroom for post processing, but Photoshop Elements is an excellent and less expensive alternative, and Google’s Picasa is free, although it has less features.
