I bought a new Canon with a nice lens to take good pictures In Egypt, but I don't know a lot about it. Since I can't use a flash in tombs and such, I will need really fast film, such as 1200? Will I have to have a tripod or will hand held work? Is there any lighting inside these places where there's no flash? If I'm not a pro, can I take usable pictures with a decent lens and fast film?
