Why the past tense? 7231 is a current product that Kodak still sells. And yes, it is used for telecine, for contact printing 16mm films, and for blowing up to 35mm. I don't imagine it's used for reversal processing, as there is Plus-X reversal film (7265) for this purpose.I have about 600 feet of Plus-X Negative film in 16mm. I was wondering how this was usually used. Did they develop it as a negative movie, and reverse in the telecine transfer, or did they make contact movies from it? Did people often choose to simply reversal process it?
Back "in the day" the negative was cut up into A & B rolls that contained back leader alternating with the scenes. These rolls were sequentially run through a printing machine, which printed onto negative film again. That gave you your positive movie "print" for viewing. Also, back in the day, they could use different emulsions for 'in camera' and for making the final prints for viewing.
If thats super 16 (single perf.) it is also good film for 16mm still cameras.
Yes, film was cut into "A" and "B" rolls if dissolves or effects were needed, but it was NEVER PRINTED onto more NEGATIVE film. It was continuous contact printed onto Fine Grain Release Positive, a film designed to make projection film prints from negatives. This film was blue sensitive only, so it would be handled in relatively bright safelight. You could think of it as a single-grade b/w photo paper, only on a film base.

1) A and B rolls are used to hide the splice which overlaps onto the black leader.
2) Negative + Negative = Positive, remember
3) Also, the popular "optical printer" is not a contact printer.

Well what is it? NEVER or ALWAYS??
Release film has a clear base, to show whites as brilliantly as possible on screen, while camera film usually has a mask. Also, release film is extremely fine grained and slow (I think Eastman 7302 is around ISO 3) and optimized for the task at hand. Printing onto camera stock is of course possible but yields inferior results.Wait, I'm confused... What is the difference between camera film and release film?
That must have cost you two arms and two legs!
Most of not all of the COLOUR negative stocks use the rem-jet black coating on the back of the film. The Black and white camera stocks just use the grey base method the same as B&W still film.Because this is camera negative film, will it still have the remjet layer?
