A Facebook friend of mine has a really big camera. He took it to Italy and posted a picture that he took of a second story window. Imagine this; on crowded cobblestone street, he has set up his tripod and the camera, which is about the size of a microwave oven. It has bellows and takes pictures on sheets of film that are as big as a paperback book. It has a special feature that allows you to raise the lens to correct for the natural tendency of buildings to go all pointy at the top when you look up. The parallel lines in my friend’s photo of a crumbling Italian building, did not converge.
