3-D PHOTOGRAPHY SEEMS DOOMED TO FOREVER RESIDE ON THE PERIPHERY OF THE MEDIUM AT LARGE, a part of the art that is regarded with mild derision, a card trick, a circus illusion. My own experience in it, from simple stereoscopic point-and-shoots to high-end pro-sumer devices like the Realist or View-Master cameras, has met with a lot of frustration at the unavoidable technical barriers that keep it from being a truly sharable kind of photography. It’s rife with specialized viewers, odd goggles, and cumbrous projection systems. It calls attention to effect to the detriment of content. It is the performing seal of photography.
That said, the learning curve needed to compose for stereo effect is equally valuable for overall “flat” composition, since you must always be mindful of building layers of information from front to back, the better to draw your viewer’s eye deep into your subject. Some will meet this challenge with a simple selective depth of field, as if to say: only pay attention to the stuff that is sharp. The front/back/sides don’t matter…I’ll tell you where to look. Others decide to arrange the front-to-back space all in the same focus, forcing the eye to travel in a straight line. Depends on what you need to say.
DSLRs allow you to elect for the former strategy, while iPhone photography, at least at this point in history, pretty much forces you to adopt the latter. You just don’t have the fine control needed for selective focus in a smartphone, any more than you have a choice shutter speed or how wide you shoot. With few exceptions, the iPhone and its cousins are marvelously adroit point-and-shoots, so your composition options lie chiefly in how you frame things up. Quickly.
This “think fast” mentality works to your benefit in the stealthier parts of street photography. The quicker you click, the harder it is to be detected, which means fewer “hey, what are you doing” issues with reluctant subjects. Even so, you have to be composing consciously if you want to establish a strong line to maximize the illusion of depth. It means deciding where the main drama in a shot resides and composing in reference to it. In the above shot, the woman lost in her John Updike novel is the main interest, but the steep diagonal of the wall leads you to her, then, as a second stage, to the lighter pair of friends in back. Framed in this manner, depth can be accentuated.
There are happy accidents and there are random luck-outs in photography, to be sure, but to create a particular sensation in your pictures, you must craft them. In advance. On purpose.
