- Mike,
-
- The best way to think of it is that all color films are are pretty much the
- same material with some different features. Chrome films (those intended for
- processing in E-6) have high contrast and saturation. For this, you have to
- give up exposure lattitude. Color films (those intended for c-41) have a
- orange mask for printing (I will not get into why right now), have lower
- contrast but wider exposure lattitude (for overexposure, that is).
-
- So, what happens when you cross-process chrome film in the c-41 process? You
- end up with an off color negative with low exposure lattitude and high
- contrast. Conversly, you can develop color film in the e-6 process and end up
- with a positive with an orange mask and low contrast (pick up a copy of Spin
- magazine and I am sure you will find a few examples of this).
-
- Don't worry about roaching the chemistry by doing this. As long as you don't
- run more than 5% or so of work like this, the process should be just fine.
-
- *DISCLAIMER* PRETTY PLEASE do not try this with KodaChrome. It is a different
- animal altogether. PRETTIER PLEASE do not process black and white films
- through color processes unless that is what it is designed to do (ilford).
