Re: Developing sheet film with a drum processor

Hi I use the drum tube processing for 4x5 to 8x10 negs. I use Rodinal 1:25 for
most films. 8 min @70f for normal negs. I fix for 5 min in drum and at least 5
min in tray to lose the purple dye. I have used up to 4 4x5 in an 8x10 tube and
even 4 8x10 in a 16x20 tube. Be sure the emulsion side is to the center and the
film does not overlap. Leave the tube a little damp so the film doesn't slip. It
may slip in the fix but more time in the tray fill fix that.
