Ah, the semantical joys of discussing “street photography”, a label that is easy to hate (and understandably so) but too convenient to abandon.
Straight off, street photography does not need to include a human let alone the face of a human. At least in my book, but there are many other books just as valid, which is why such derision exists for the term street photography. Moreover, for me, street is not a contest to see who can be most machismos by shooting straight on (Bruce Gilden wins if that’s the game, and he’s not exactly applauded for being more ethically considerate than those who shoot on the sly).
This topic was brought up many years ago on this site, and since then, I started to mentally inventory back shots taken by the generally recognized masters of street. Among these photographers, you’ll find not only a good number of ‘back shots’, but also ones that prove to be excellent, at least I think so. Does this mean everyone is obligated to like back shots? Of course not. Even so, just be careful about projecting personal preference on to others, especially when trying to establish what are already elusive definitions.
People are forms and forms can be interesting from any angle, particularly if incorporated into a broader scheme that includes a compelling use of lighting, contrast, timing (the decisive moment), geometry, lines, movement, action, color, and, of course, composition. And if they suggest a story (a photo of firefighters’ backs as they rush towards a burning building in the background), that’s all good, too.
In any event, photography does not require a statement to succeed; abstract anyone, a luscious black & white photo of a flower? And faces don’t reveal truths but merely an expression caught within a fraction of a second that are oft-prone to misinterpretation given photography’s inherent lack of context and narrative. But have a field day with fabricating your own story, I do it all the time! Ain’t art fun?
This said, if you’re still guided by a storytelling agenda, a back is no less vague than a front within the confines of photography, so go with it from here. Besides, vagueness can sometimes add alluring mystery or tension.
Now, is there a lot of bad street photography that use back shots? Absolutely. I’ve taken an exhausting amount myself. And there is some truth, particularly with beginners, that shooting from behind is less intimidating than shooting the front, and the photo can appear a lazy way to include a human for the sake of including a human.
And because a staggering number of photographs are circulated by the minute, an immeasurable amount of bad ‘back shot’ photos, like any other type of bad photo, are easily available for scrutiny, leaving a broad bitter taste in the eyeball. But this consequence is a disproportionate one, since exceptional (or maybe even just “very good”) photos are, by nature, limited (subjectivity acknowledged).
Is there a stalker element to shooting from behind…well, street photography has a stalking element irrespective of the photographer’s position, although I get that someone photographing in close proximity is seemingly more commendable than some guy with a 400mm stooping behind the bushes (or a car for this discussion). This said, a back shot actually upholds more privacy than does one that includes the face. In the end, you have to respect your work enough to justify its inexorable evasiveness.
What street photography is definitely NOT are ONLY photos of people who are aware of being photographed or who have interacted with the photographer. Again, I stress only! Yeah, call me a hypocrite, maybe I deserve it, but I'm putting my absolutist foot down on this. Good lord, if this were a prerequisite, do you realize how many excellent photos would have to be extracted from the street photography libraries of Henri Cartier-Bresson, Garry Winogrand, Vivian Maier, Robert Frank, Alex Webb, Bruce Davidson, Daido Moriyama, William Eggleston, Lee Friedlander, Joel Meyerowitz, Helen Levitt, Fred Herzog, Elliot Erwitt, Fan Ho, and Saul Leiter, just to name a very few. You would be better off telling me that wildlife photos are ONLY photos of animals in zoos.
After all, when defining street photography, if there is just one thing on which most (if not all) photographers agree it is that candid photos of people play a key role. Some argue the only role; not me.
Ultimately, the ambiguity of street photography (hard to define but I know it when I see it type thing) makes the term subject to criticism, but the ambiguity also militates against restrictive parameters, which is a positive thing. That is, a good photograph is a good photograph, and just because it might not meet someone’s arbitrary (and thus disputable) standard of a photographic genre doesn’t suddenly render that good photograph bad. Good photography is hard enough. No need to make it harder by trying to placate the dubious impediments of self-appointed Facebook lawmakers.
