Hi Marcelo, It is certainly a good idea to check the manufacturer's literature to see. I know that for a long time Kodak Tri-X sheet film was a different emulsion than the 35mm and 120. Also I think, but am not certain, that T-Max sheet film may have been different that the roll film. With Kodak's somewhat recent re-formulation of all B&W films, I don't know if this is true any more or not. It does point out the possibility that there may be differences in other manufacturers' films. Sometimes there is a difference in processing between sheet and roll films because of the processes used: small tank v. tray processing, etc. If you like to test, and to be on the safe side, it might be a good idea to do separate tests on the same film in different formats.

Subject: [pinhole-discussion] Tests in different film formats Hi, A questions for those of you who test films. Speaking of the same film, if I make a test (exposure or development, or whatever), say, in a 120 roll of brand X, are the results still valid for the same film in different formats (35mm, 4x5 sheets, etc.)? Many thanks. Marcelo Marcelo Mammana __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier.
