Thanks everyone. Andrea, I agree that Tounis' shot is very captivating... I really like the combination of dramatic sky and peaceful landscape.

My photo in Banff was taken at another sure-fire spot for sunrises, and it's always fun going there because you just don't know what's going to happen. Given that it was fairly windy, I opted for a long exposure to blur the clouds. My Lee Big Stopper gave me a 3-minute exposure, which was perfect.
