Kodak Rapid Process Copy 2064

[rjas]

I have a 100 foot roll of this, expired in 07/2000. I read that it is a reversal black and white film for copying? I read somewhere that it can be processed in Dektol, but wouldn't that just produce negative images? Anyone with any experience with this film?

I used this film to copy radiographs. I ran it in rapid x-ray processors, in-and- out in 90 seconds or less at somewhere around 94 degrees F. It made jimdandy slides of viewbox-lit transparencies, but as a pictorial film it produced terrible gray, flat images totally lacking in contrast, and that was using the copy stand in attempt to make black and white graphics. I can only imagine it would completely fail if shot as a reversal film for normal photographs. X-ray developer is metol and hydroquinone, and the fixer is hypo. Simple stuff, like in our darkrooms.

You may have to play with dillutions and times to make this sort of film work, but I'm sure its doable.

If you find that the stuff lacks contrast you may want to use two different developers back to back (like, for example, Rodinal 1:100 for a couple of minutes, then a water bath, then something like Dektol for another 5) to work with it. I first read about this sort of processing in the formulae section of APUG (see an entry by Dr5), and I've processed some extremely flat negs with a couple of minutes in Rodinal and a few minutes in ID-78 (my paper developer). The resulting neg had a much better contrast range than just Rodinal (not enough contrast) or just ID-78 (not enough shadow detail). Mixing soups really seems to work.

However, my brief experience with very, very contrasty film was most successfull with 510-Pyro, to which fellow APUGer Jdef introduced me. Simply dillute the stuff 1:500 and develop for 20 minutes with minimal agitation (twice, maybe 3 times).

I'd say that you should spool a few frames of the stuff, shoot it, develop it, and adjust as you need. Your E.I. will most likely fall in the 3 to 25 range, I'd guess (in all my ignorance).

BTW, I've read of direct to positive films, so this one you have may be one. Just soup and fix, and bam! Transparencies...

It might be a very low speed direct reversal film used to duplicate microfilm like 2468 and 2470 and 5360. I don't understand how it works but it was pre-solarized at the factory and you use regular b&w chemistry to develop a positive. Lookup D-32.pdf and use the 2470 curves as a guide. Notice the D-max is low.

I still have a full roll in the freezer.. circa 1980. I too used to copy a lot of autorads and "blots" on this stuff.... exposures around 45 seconds at between 4.5 and 5.6 It has a rather blue base such that radioographers would see the slides the same "blue" as the originals.

ISO is "about" 0.06 (repeat zero decimal zero six) and can be developed in just about any B/W developer.... DK 50 for 6min at 20°C for multiples (in the deep tanks), and HC110/B if in a Kinderman for just one or two rolls.

hey i got a load of that film rpc film too. i generally use hc110 as a standard dev, and experience with the results from this dev or dev times?
thanks
any news with your results?

The obvious answer is to snip off a short roll and try. The big problem is to determine a film speed. Most of these copy films are pretty slow. Only one poster so far (Kobin) seems to have had experience with this film. His remarks make me think that this is one of the pre-fogged automatic reversal films that Kodak produced for a while. They gave a positive image with regular development - sort of a solarization effect. Maybe Kobin could amplify on his experience.
