Subject: [pure-silver] Tri-X in XTOL
My developing chart that comes with the XTOL data has a
column for "Format". Plus-X for example gets two
different rows, one each for 135 and 120.
Some films come with a row with 135/120 in the format
column. So I'm a bit confused - since I know Kodak likes
to be very specific - when I see Tri-X 400 only has 135
in the Format column. Should I assume the same times for
135 and 120?
Thanks,
Elias
Times for 35mm and roll films of the same type may be
somewhat different. I am not sure what causes this. It may
be an assumption Kodak is making about the amount of
solution in the tank or it may have something to do with the
overcoating of the films, which can affect the "induction
time" of development. In some older films you can see
differences in the characteristic curves for the same brand
of film in different sizes.
