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
