I think I settle down for developing TMY in XTOL 1:1 at 20C at following
procedure:
1 x 30sec - non-stop inversion
16 x 30sec - 4 inversion in 5sec
1 x 45sec - no inversions
This way total time is 9:15 and negatives are nicely full just enought for
getting nice shadow details and scanning. I am starting clock after pouring
xtol in tank, than starting pouring it out 10 sec before time is up.
