Taken through a wire mesh covered opening on the observation deck of the Volunteer Park water tower at full zoom (300mm), the sides of the frame are a bit dark where the edges of the mesh are fuzzed almost to obscurity. That gave the original photo a bit of a lomo-like effect that I decided to highlight by adding some oversaturation, a histogram equalization and a little bit of grain, in order to give this the feel of a postcard from the era of the Seattle World’s Fair (coincidentally, the very year I was born), and that treatment is more evident at the large size.
