5 Frames (and a Warning) with FPP’s ISO 6 Yeti film in a Nikon SLR – by Clifton Dowell
I bought a 35mm roll of Yeti on the advice of a friend on Flickr but never had a clear idea of how I would use a film rated at ISO 6. I knew it wouldn’t be shot on the fly, of course, because I’d need to carry a tripod and take notes. So my single roll spent a couple months sitting on my desk.
Yeti is a blue-sensitive B&W film, which means it can only “see” the blue part of the spectrum. It is similar to orthochromatic film in that it is only sensitive to part of the visible spectrum, except in this case, the sensitivity is limited to the blue part. Yeti is available from the Film Photography Project and is described on the website as an estar-based, positive motion picture film intended for direct contact copying titles and mats in motion picture work.
