99.9% (maybe more) of photos I've taken do not have people in them. Recently, I started trying people pictures: pictures of my friends' children on the playground, some portraits of my niece. But, I really love pictures I see of "unfamiliar" people, à la National Geographic. The problem is that I'm not brave enough to go up to a stranger and ask them if I can take their picture. Will the person be flattered or insulted (for example, if they are homeless or don't look like me)? - How should a photographer approach a person? - When is a photo release form required and how do you ask them to sign it? - What about when you don't speak the same language? - If you want a candid photo, is it ok to take the photo then ask for the release afterward? - What if the subject is a child and there is no parent around?
