Before I get castrated, let me start out by saying that I think the Bechers are superb photographers. I spent an hour browsing through some of their books. My guess is that there is a real reason they are documenting the building forms to the vast lengths that they have already. However, when does one say - enough? After the fiftieth different form of water tower (or gas tank, or grain elevator, etc.) I began to wonder ... Does anyone know enough about the Bechers to know what they are up to? Have they been commissioned to do this work?
