Eastman Kodak produced this camera in four different formats: the standard 5x7 and 8x10 formats but also an 8.5x8.5 and a 7x11. The camera pictured here is that latter 7x11 format. And it is quite understandable if you are wondering why 7x11? It is an interesting format. Slightly more rectangular than 8x10, 7x11 is ideal for landscapes, banquets or large group portraiture. Even more interesting, 7x11 has a ratio of 1:1.57... just a hair off from the golden mean of 1:1.618. But hey, you might exclaim, I did not come here for math! Put in simpler terms, 7x11 is a beautiful rectangle. Some might even say it is a near perfect rectangle. And while most camera stores don't readily stock 7x11 film, Ilford does supply their FP4 and HP5 in that size once a year as part of their ULF program.
