Art, a bit beyond what you asked for but... A few years back I attended a Leica seminar on Cape Cod. A three day contest had as it's subject "RED". Next morning I found myself with two dozen others shooting a red fishing boat. Not one of the photo's in the contest were anything like anyone else's.
One of my favorite photos last year was taken at the Asbury Park get together. I would like a local exchange from an APUG meet. It's just amazing how we see a subject differently.
