a bit of background for this week's questions: for a class of mine, i read a theoretical analysis (haha) of photography. the author compared the camera to a gun.

• are you open to people taking pictures of you?
• what about strangers approaching you with such a request?
• would you participate in a candid session with a photographer (act as though the photographer and camera are not present)?
• do cameras (and nowadays, camera phones) cause any violation of a person's privacy?
• is a photograph still a photograph if it's been altered?
