WEell, all I can add is that I took the same scene with a red filter on the EFKE 25 and then put in a holder with TMAX 100 and shot the same scene with the same red filter on. I will process them in a few weeks when I get back from my trip and see if anything usable comes out. If so, I'll scan the negatives and post them in the technical galelry for general interest, if any.

Thanks for your help!


P.S. I guess the EFKE will come out very thin as I only gave 3-stops extra exposure for the filter. Hope the TMAX negatives are good because the scene was lovely, high altitude, sotrm clouds interesting hills in the foreground, sage brush, etc.
