David Terraso Posted August 17, 2004 Share Posted August 17, 2004 I bought one of those old 16mm cameras that use the 50' magazines. A place nearby has some mags loaded with Plus X Negative film and said I could process it as reversal with their lab. Would that work? What would that look like? I've read some stuff about cross-processing reversal as negative, but not the other way around. Anyone know of a lab that will process the 50'magazines for a reasonable price and give me back the magazines? Cheers, David Link to comment Share on other sites More sharing options...
Premium Member John Pytlak RIP Posted August 18, 2004 Premium Member Share Posted August 18, 2004 Processing a B&W negative through a B&W reversal process will give you a positive image, but the contrast will likely be quite low, and the curve shape unpredictable, since it was not designed for that process.

bwff Posted August 19, 2004 Share Posted August 19, 2004 It will not work. Bleach in reversal processing will clear out any image. Link to comment Share on other sites More sharing options...
David Terraso Posted August 19, 2004 Author Share Posted August 19, 2004 Thanks for the advice. I certainly won't be trying that out -- unless I have money to burn. Cheers, David Link to comment Share on other sites More sharing options...
Premium Member John Pytlak RIP Posted August 19, 2004 Premium Member Share Posted August 19, 2004 It will not work. Bleach in reversal processing will clear out any image. That is true of trying to process a B&W film in a COLOR process. Link to comment Share on other sites More sharing options...
soundcutter Posted September 12, 2004 Share Posted September 12, 2004 This is an interesting subject. I had a go at deveopling some 16mm B&W reversal at home recently (out dated 7278 given 1/3 stop more exposure). Although the film density was a bit thin, (I'm assuming this as the sprocket area was not black, but more of a darkish grey) the image was great and encouraging. I'm up for some more experimentation in this area. (time consuming as it may be) Reading above about the possible low contrast when processing B&W neg as reversal, will pushing the film a couple of stops increase the contrast? would it be better to push 7231 rather than the faster 7222 stock ? or am I really asking too much of the film here? I'm an experimenter, and so not concerned about the inevitable golf ball sized grains in the emulsion as a result of this. Chris (UK) Link to comment Share on other sites More sharing options...
Premium Member John Pytlak RIP Posted September 15, 2004 Premium Member Share Posted September 15, 2004 Experimenting is fine. But Kodak designs and optimizes each film for its specified process, so you are on your own. Link to comment Share on other sites More sharing options...
