filmscanners: BW speeds & development for scanning
Does anyone have a 'rule of thumb' for a starting point on conventional
silver BW film speeds & development times when the negatives are intended
for scanning? Do scanned negatives need a different dmin for usable
density compared to enlarged negatives? Do highlights block-up more easily
or less? In a conventional darkroom, I always got better results with more
exposure & less development than Kodak's tables. Ansel Adams' methods
intended for diffusion / cold-light enlargers worked well: Tri-X @ ei200
or FP4 @ ei80, dev in HC-110 about 15% less than Kodak's tables.
After a long lay off of BW, I'm re-starting with Delta 400 & 100 Delta,
Xtol & an SS4000. No printer yet. Specifics would be nice but a general
guideline would be fine.
Thanks,
Bob G
