Rob, As you know, I normally ignore landscapes and refuse to comment on them, or if I do comment my comment usually echoes Walker Evans's famous: "so what?". But both Andrea and Timo can see! Very, very few landscape photographers can do that. I think I'd also add Chuck Kimmerle to that list on the basis of his winter work in North Dakota. The three of them are about the only landscapers I've seen on LuLa who don't rate a "so what?".
I'd love to see Andrea do some street work, but his "violence" shot doesn't fall into that category. It's staged and it's derivative, and I can find essentially that same picture in just about any magazine that carries "detective" stories, or propaganda about violence toward women.
I agree with you that the vast majority of good photographs feature people in one way or another, or at least feature their handiwork. But we disagree about the "violence" picture. That's unusual.
