FOMA Developing Disaster - Can anyone help?
Posted 08 October 2005 - 09:17 AM
I am at my wit's end with processing FOMA R100 B/W reversal. I can process severl other B/W stocks quite adequately, but Foma seems to always produce a very odd washed out and 'solarised' effect, a little like there is a step in the characteristic curve of the stock - blacks and dark greys working out, then a jump to light greys ...
I have tried everything I can think of or that others have suggested. The frame lines and film edges come out a nice dark black so I think I can say that the film is not foged or otherwise damaged, and that the reexposure and the second development are working fine.
I know this stock has a strong anti-hallation layer (the reason it cannot be processed as a neg) and that it is a silver rich stock. As far as I can tell the issue must have something to do with one of these.
I have tried long rinse times, long bleach times ...
Could my problem be the effect of the film being x-rayed in transit to Australia ... I don't know what xray exposure would look like ... but I assume it would be an all over foging. Any one know the effect on reversal stocks?
Could my problem be to do with something in the water I use ... something that affects FOMA but not Kodak or Kahl (ORWO)?
I have a quantity of this stock in my fridge, I am desparate to find an answer.
Can anyone help?

Just letting people know that I have finally solved my Foma problem. It need considerably more clearing time than other B/W films, possibly because of the anti-hallation thing. Any way, I got a result - finally!
How much more time?
