Canada's 150th and two recent photo challenges got me thinking about how to show off Calgary's iconic landmarks in photographs. That, in turn, got me thinking about how I like to search images and blogs when we're going to visit other parts of the world, to get some ideas for how to come home with great images from away. Since I benefit from other bloggers' advice on how to photograph their home turf, I thought I'd return the favour... First up? The Calgary Tower.
