Are there any rules/legal issues with taking pictures of other people? Say, for example, you are at a park and just want to take pictures of a couple walking by, or the family playing on the swings, etc (I am not talking of family/friends but rather of strangers). I have heard things about model releases and such. I have been taking a lot of pictures of nature and would like to get better with my people photography yet I am unsure of how to proceed. Do I need people's permission to take their picture? I do believe if it were of kids, I would get their parent's permission. I would be a bit creeped out if I saw a stranger taking pictures of my kids without talking to me first.
