One of the great things about a waist level viewfinder is the ability to turn the camera 90 degrees up and have the ability to compose by looking straight ahead. Looks really strange when you’re standing there doing it, but it’s worth it. Look at those converging lines!
These are some of my favourite buildings, the architecture is brilliant. My sister used to work in one of these (it may have been this one), way high up. The TD Towers were designed by Mies van der Rohe, one of the pioneering masters of modern architecture. He even designed the font used on the signs of the buildings. Needless to say, I spent a good portion of my time here that afternoon and got some nice shots.
