Hi everyone, i'm new and wondered if you could help me. We are going on holiday in January to Canada, I'm not sure what speed of film to use for the snow and Niagra Falls etc. At work they have been selling off some films half price so i've bought some Kodak 400 speed. I have a Canon EOS 500N and tend to just use the auto mode, therefore I just point and shoot! (Sorry, lazy I know!) Do you think the 400 is suitable or too fast? thanks in advance for your help.
