Does this help http://www.fujifilm.com/JSP/fuji/epartners/bin/F-250.pdf ?
This stuff is for movie cameras, motion picture stills taken on 35mm cameras use ECN-2 processing. Ziggy Hi, gang Some days ago, a friend was given a bulk of Fuji 250T film, exp. date unknown. She loaded some rolls, and gave me a couple to test. I did some web research but the only info I found about this film was obscure references to 35mm and 16mm negative movie film. So, knowing only it was tungsten neg film I exposed it and sent it to develop. My dear photofinisher almost kills me. The film went out with a layer of a dark substance wich sticks to the fingers like laser-toner dust. He thought I ruined the developer and filter of his machine, but luckily not. The image is there but covered by this dark layer. He thinks it's another process film, maybe the previous to C41, or something more obscure. Somebody knows what da hell this film is?
