Also, if you agitate too much it will lead to overdevelopment and, therefore, also to more grain.
Last I will comment on the use of Rodinal with Tri-X. This combo is GREAT, but it is a good thing to experiment with rating the film 250-320 instead of the 400 it says on the box. The reason is, that Rodinal decreases the speed a bit.
Please correct me if I'm wrong, but this what I have been told and experienced.
Hi M, please help me understand the different effects again.
If I use Tri-X 400 and expose at 320, do I ask the lab to process at 320 or at 400? In doing either, what effects can I expect?
Thanks M!
