I am shortly off to Canada for a holiday and am pondering whether to buy film here or wait until I get there. I have 2 bodies and am looking to shoot velvia 50 on one and an ISO 400 on another (possible wildlife with telephoto zoom). Am I best to purchase and develop my film in Canada? I am going to Alberta (Calgary -Emerald lake - Banff - Lake Louise - Jasper) Does anybody know where I could buy film in any of these places and of any labs that process slide film. I am travelling from the UK so am guessing like everything else it would be cheaper to buy/process abroad plus I would avoid the potential x-ray problem. Any thoughts and advice would be appreciated.
