If street is not dead, the simplicity and redundancy of the genre (open ended as it might be), has increasingly whittled away whatever remaining new ground there may be to explore. And to clarify, when I say "simplicity," it is not derogatory by any stretch, as I'm simply saying that street photography is fairly austere in its structural demands much the way rock 'n' roll is with its 'three-chord' backbone.
If you want to play straight, loud, four-four rock, you're simply going to have a harder time creating a new influential movement than in the past, and to nobody's fault! This said, and I think it's analogous to street photography, there are still some great rock acts around, even if their derivations are showing a bit more brightly…
Besides, getting back to the semantic angle, hopefully not too much, what is street? I lived in large cities, took photos of my surroundings because, tautologically speaking, it was around me.
Put me out in a farm, and I'll continue to go outside to take photos of my surroundings….OK, then get bored and move back to a city.
If one is living in a city or even town, where people assemble regularly, and at least a few sidewalks and buildings spot the grounds, then how can "street" die, lest photographers simply abandon their cameras before stepping foot into an urban environment.
And of course, we can reasonably ask does street even have to involve the urban, since perhaps just 'life' is fine, as in signs of life (as in people not even required).
But how fresh can street be?
I see kids today looking like hippies from the late 1960s, punks from the late 1970s, and rappers from the late 1980s---and did kids from the northwest US ever really toss their plaid shirts just because the co-opting fickle fashion mongers declared grunge dead?
Retro referencing has solidly become a defining aspect of the current, perhaps more so than at any other time. If anything, photography has had ample opportunity to jump off this circular flow with the advent of digital and the ease, in relation to the wet darkroom, of manipulation.
Yet, street photography is generally not about getting all Dave Hill, and look how many of its practitioners haven't even moved to digital, or at least, like me, maintain a hybrid approach (film-scanner). But then again, this is the simplicity of it, which is the beauty of it, but it is also its burden in the pursuit of originality untainted by pretension.
You like jeans and T-shirts, but you want to be different; that's a tough one, especially since every haircut possible was tried by 1983. Or maybe you don't care about being different, just about being comfortable with yourself.
An upcoming era that will match the 1930's to 1960's; doubtful, at least in my lifetime, but death, no. Not for me, because what else would I do?
