Using Templates

To get started, select a template which is identical or similar to the process you wish to use. Generic versions of each process (C-41, E-6, RA-4, B&W Film, B&W Paper are included along with the most common brands. Most of the color processing times are pre-set for Rotary processors (JOBO etc...), but you can modify these times easily for manual processing.

Modify the Template as follows:
