All black and white films are developed in replenished XTOL. This developer has good sharpness, fine grain rendition, and lends itself well to both pushing and pulling. Every film is different, but most can safely be pushed 3 or pulled 2.
Rodinal is also available by request for slow speed films and special circumstances like stand development.
Color Negative (C-41)
I use CineStill’s C41 and utilize a temperature control bath to maintain a consistent 102°. With this system I can effectively push up to two stops, or pull one stop. I can push or pull farther than that, but it isn’t recommended.
I will cross process E-6 in C-41.
