Umm lets see, I'm gonna take a beggining photography class this summer, and I decided on purchasing an SLR camera. I read a lot of reviews and purchased a Canon Rebel Ti.. now I'm concerned about what types of film i should use. As i said before its a class and i don't know what to expect

A) what type of film do you people recommend for just regular color photos?

B) film for black and white?

C) what does ISO 800/400/200 mean? quality?

thanks a lot
