Kind of on the same vein as the Distrust thread.. I was wondering if you take pictures of someone without their knowledge, are you obligated to get permission of them to use the photo (publish it on the web, sell it, etc.).. Personally I think it is only courteous to do so, but was wondering about the legal side of it. I have a couple shots that are really interesting, but I hesitate to post them because I wonder if the person would want me to. Do you ask permission before you shoot someone? Or just children?
