I tried a test of Delta 3200 in Microphen this weekend. Exposed at EI3200, developed in Microphen (1:1) for 18m at 21.5C.(posted 8680 days ago)As expected, shadow detail is a bit lacking at EI3200. I'd guess the probable true ISO would have been between 1250 and 1600 (using the 0.1 above b+f definition). Contrast was good (i.e. not too high) and apart from the lack of shadow detail the negatives don't look bad. Maybe a little thin, but since I'll be scanning them that's not a bad thing.
There was one odd thing though. I haven't used Delta 3200 before, but it appears to me that the film base is slightly hazy, i.e. looks like a very lightly frosted glass. I though maybe I'd underfixed, but when a refixed a short section nothing really changed. Reticulation is always possible, but my dev, fix and wash are within +/- 1C of each other so reticulation is very unlikely. Maybe it's just a characteristic of the film? Has anyone else noticed this effect?
