I'm going to start taking pictures at school dances, and need to know what type of lighting equipment and backgrounds I need. I'll be working with a Rebel XTi and the kit lens. The school that I'll be taking pictures in will also have fluorescent lighting, if that makes any difference. I plan to buy a digital radio slave to go with it. Also, what type of backgrounds should I get? I don't think I'll need anything special, because they just want a basic picture. If their is a theme, the school will design everything for me. I was just going to get a standard grey muslin. Any suggestions or help would be appreciated.
