Subject: [pure-silver] Tri X 320
I recently purchased Tri-X 320 in 120 format and I
can't find Dev Times for it. Digital Truth only lists for
sheet film.
Any ideas?
Thanks
J

Ilford does not seem to list the ISO-320 version of
Tri-X in its data sheets. I think the best you can do is to
compare developing times for this film with others where
times for both are given. The Kodak data sheet for Tri-X,
which lists both emulsions and both roll and sheet film, is
a good place to start. While the ratio of time is probably
not exactly the same for some other developers this
comparison will give you a starting place.
Kodak's data is more complete than most other
manufacturers since it tells you the contrast index the
charts are for. Finding the right developing time will take
some experimentation because B&W processing is not
standardized. I've found Kodak data to be pretty reliable.
