How about a thread for photos made with extremely wide optics?
I'm thinking a lens with a focal length of well under half the image diagonal. That would limit us to 47mm for 6x12, 65 for 4x5, 90 for 5x7, and 120/121 for 8x10. (You guys can do the math for larger formats than that )
Here's an initial entry:
Cannon and French Castle, Fort Niagara, September, 2009. 6x12 format on Velvia. 47/5.6 Super Angulon (theoretically a 6x9 lens but with -just- enough coverage for 6x12 if you don't mind about four stops of falloff). F/22, but I just didn't write down shutter speeds that day. For critical work, I'd need a center filter, though this is about as extreme as it gets by using Velvia with a lens right at it's coverage limits. I don't really mind it here, though--it helps isolate the subject while still showing the open emptiness of the place.
I originally scanned this on the Epson V750, but for some reason it could not handle that sky gradation without banding strangely, so I scanned it in two parts in my Nikon 8000ED. Aligning images isn't quite as easy as people say it is, when working down to the pixel level for a 150-megapixel image. I guess I need a new computer!
