Can I know if I am using a SLR Camera not a digital. Film have already been loaded. Can I change my lens? Will the light effect the film causing the photo be gone or what? :roll:
Like everyone else said there is no problem changing lenses. Just don't leave your mirror exposed for to long, never know what is floating around. Especially if you are doing nature photography in the middle of the woods.
Or the beach. Beware SAND! Really, watch out. Sand is pure evil. Get it on lens glass or on the mirror and you're relying on a blower brush and the goodwill of any passing deity. ale: Like I said, beware.
