As a recent convert to "street" PERSONALLY I've stopped worrying about the label!
There's so much cross over between street/documentary/reportage that you can debate all day long if something is "street" or not
Then there's the endless discussions around how to process your street shots. The super purists will tell you, that if you so much as kick a bit of litter out of the scene (before you shoot) then you have influenced the shot and it's not pure street (you can imagine the views these people have on cropping, dodging/burning etc
) at the other end of the scale you have those that critique street as if it were a fine art studio scene, this is wrong, that is wrong, that's not sharp enough etc etc
For me?
Street as a genre exists to offer a visual, and ideally, an emotive impact to the viewer (as of course does most photography) but the difference is, your viewer won't necessarily have any intrinsic connection to the scene. It's not a landscape that they'd love to visit or the happiness that reminds them of their own wedding (by way of examples)
Street is an intertwining of human and humanistic. It documents and demonstrates.
The photographer's own personal interpretation of human and humanistic is their street voice.
Is your first shot street (according to my own views as detailed above?)
Yes.
The statue/sculpture (I don't think it's a street performer, but what I'm about to write will still apply) is art, art imitating life. The people are life, they are interacting with the art, they are imitating it (that it in turn is imitating life)
So yes, human and humanistic, combined really rather nicely in my opinion. Good shot.
Shots two and three I would PERSONALLY file under documentary (no harm in that, it's not a criticism) but they -to me- more tell a story of humanity, rather than what it means to be human.
Obviously others will completely disagree with me! But FWIW that's my answer to the question you posed!
