Interesting. I always wonder if this approach really reaches anyone. But you never know. Good idea to shoot it in b/w- it adds to the starkness of his message.
I have often wondered the same, is it worht the attention, which is about all it accomplishes I would think. I think it would work to redirect that energy.
the B/W really works well here allison. it helps emphasise the gentleman's message ...the two men on the bench ignoring him walking by makes this a classic piece of street photography
