I've been wanting do some street photography in a bad neighborhood in SF for years but never done it cause I can't think of a safe way. I want to take photos of the projects, drug dealing, homelessness, prostitution and poor art students in that area. I don't want to use zoom lenses, maybe a 35mm or 50mm. It was suppose to be a topic I wanted to do in school for my semester final years ago about problem in SF. I never did cause I was kind of scared but i want to do it now. Anyone has this kind of experience that can share with me? Safety tips please.
