The output ( or ASA input) seems the same, regardless of the film size. The emulsions I think are the same. The backings are certainly different, and the antireflection backings are different. However, I get the same times in development for all 3 film sizes for the same negative densities. BTW, I found that developer exhaustion is an issue with Tmax RS. In my tests, you need a minimum of 35-40mL of concentrate per 8x10 equivalent. Thus, in my JOBO, using 3 rolls of 35 film per run, at a 1:5 dilution factor ( 4'30" at 75F) , I use 600mL of diluted developer ( the maximum liquid allowed in a JOBO CPE2 is 600mL). 100mL of developer concentrate, 500mL of distilled water. Note this is not a standard Kodak dilution, it works for me in my darkroom. If you use much less developer concentrate per roll, you end up losing density as the developer exhausts. For those into developer times, etc. I recently tried a set of negatives at Kodak's suggested time for this film/developer/ASA combination and found the negatives way too dense. I have no clue on TMAX 400 films. I do not use them. Frank Filippone red735i@earthlink.net Does anyone use this with their TMAX films instead of the conventional developers? I understand that the sheet film people use it - very diluted - to good effect. But I'm wondering how it works for 35mm?
