I photpragh people in UT all the time. Just grab a rocket launcher and do a screen grab when you toast them. =)
If you’re looking for inspiration, just step out your door into the world and start taking pictures. Don’t try to be artsy about it by tipping the camera or other retarded things that people do. Just try to capture the life that goes on around you. When you get home go through the pictures and see which ones catch you. After an hour or so of taking pictures, something will have caught your eye and you’ll have some nice pictures.
