OK so I really want to take Photography class for school. I was looking at the beginners course and it says a 35mm camera is required. Is that a film or digital camera? Any links or info on them? Any recommendations on which I should pick up? I'm thinking this is gonna be a film camera, but i really don't know. If it IS a digital camera I want oen that is compatible with windows AND mac, and that isn't too bulky but is really good. Something below 800$ would be good. ANY HELP??
