Coffee and tea have been experimented with over the years as staining-type developers for film. There is a good article on the RIT web site that also makes reference to using coffee as a print developer. Try it and see. Expect some long development times though: http://www.rit.edu/~andpph/text-coffe...

If the frame numbers do not appear then the film was never developed prior to fixing. The fixer clears everything that isn't developed. Even if the film was not exposed, the frame numbers would appear after development as these are pre-exposed onto the film edge. The usual explanation for this is th...

It depends which film it is. Cut off about 1' (30cm) of unexposed film and develop it for 5-10 minutes in full strength D76 (time does not need to be accurate). Fix and rinse. You should now be able to see the edge markings (frame numbers etc) which are pre-exposed. Hopefully, you will find the name...

If you go to our main page at http://www.digitaltruth.com and follow the link to the Massive Dev Chart, you will find a push processing chart listed in the menu on the left-hand side. You will get some negatives from this roll, but pushing a medium speed film this far will not produce a great result.

Hi Jan, I'm not sure whether this is the best way to proceed due to the different compositions and characteristics of the developers. Have you tried developing Neopan 1600 in Rodinal? You should get plenty of "bite" especially at 1+25 or 1+50. I would also recommend TMax Developer for this...

Try 10 minutes. It should work out, or be very close. Any time you use is only a starting point, so test any time that seems right and take it from there.

21 DIN is equivalent to 100 ASA/ISO. DIN stands for Deutsche Industrie Norm and is an older European standard which may still be in use, but should have been superceded by the ISO standard. If the film is very old, then it will almost certainly be useless. If it has been exposed the best you can exp...
