Say what you will, Russ but you are critiquing. And that's fine, I don't mind valid, constructive critique at all. If you're going to do it, at least have the balls to admit it though.
I do understand the difference between street and documentary/PJ. I also don't think the two are mutually exclusive. Just as PJ can also be artistic. Just as a beautiful art image can also have commercial value as stock. Very little fits into neat silos.
WRT posing, which of these looks posed to you? In fact I said that in all but one, none of the subjects knew what I was doing or were aware I was taking a picture of them. If you mean posed from the standpoint of posturing, or strutting, or preening, or similar, which of the subjects in these appear to be doing that? Looking in a shop window is posing? Sitting on a step is posing? Kissing is posing? Walking along the street, even in a wild costume, paying no attention to others is posing? Walking along a street holding hands is posing? Now, had these been taken during the Pride Parade later in the day, I'd agree completely even if they didn't know I was taking their picture.
Whether a 'good' street image can be made in such a situation is a matter of conjecture. As noted earlier you have a very specific and very restrictive definition of street photography.
And to be abundantly clear, when I posted these I made no suggestion that I thought they were 'good' examples. So don't project that mindset onto me.
You say that a good street image should have some ambiguity. I think the first 4 do that, particularly the 2nd, 3rd and 4th. Do you know what the man in the 2nd image is or is doing? Is he a street dweller begging for money? Is he a day labourer on a break or waiting for a ride home? What is he looking at? Did someone just walk by and make a snide remark? Did someone call his name? What does the man on the right of the third image thing of the two gay men kissing? Does he approve or disapprove? Is he jealous that he doesn't have that kind of passion in a relationship? What about the two men? Are they in a relationship or did they just meet the night before and have a night/morning of sex? What does the guy in the wild getup in the 4th think of the trans who's walking beside him? Are they together? If so, why the odd look?
WRT the idea of telling a story, I wrote earlier what Winogrand thought of that concept. I'm of the same position. A picture can just be a picture. Even a good street picture. Quite honestly I sometimes get quite tired of the idea that a photo has to tell a story. It doesn't.
