This is the George Eastman House in Rochester, NY. I shot this a while back when I was working on a scanning project for them. The House and adjoining buildings are home to the International Museum of Photography and Film. If you every find yourself in the Rochester area, this would be an excellent stop especially for those interested in the history of photography. George Eastman founded Kodak and for years his company dominated the photographic industry.
George was not a fan of outsourcing and he wanted to insure that every component of their cameras, film and chemicals were manufactured by Kodak. The photo below shows an early Kodak lens with red and yellow filters that fit over it. I put a US penny in the photo to give an indication of the size. The lens has 4 aperture positions marked 1, 2, 3, and 4 and shutter speeds of T (time), B (bulb), 25 (1/25 sec) and 50 (1/50 sec). The lens and filters are on loan from my nephew Mike. Thanks mike.
