- I would like to suggest an experiment:
- Expose 3 pieces of XP-1 film to identical subject matter.
- Process the first piece in C-41.
- Process the second and third pieces in D-76 as you describe.
- After the third piece has been processed, put it in C-41 bleach for
- the recommended time. Rinse. Open up the tank and expose it to strong
- light for a minute or so. Then process it in standard C-41 for the
- normal times.
-
- You will now have 3 differently processed pieces of XP-1:
- 1. C-41 processed, contains dye image made initially from color developer.
- 2. D-76 processed, contains silver image, dye couplers are still in the
- film but not used.
- 3. D-76 - bleach - C-41 processed, silver image made first, converted
- to silver halide, rendered developable by light, dye image formed when
- the silver is redeveloped, and then the silver removed leaving only
- dye image.
-
- Make prints from the 3 pieces of film, and examine grain, sharpness,
- contrast, etc.
-
- This is indirectly related to a technique described in Darkroom & Creative
- Camera Techniques, "Color Print Contrast Control - Boost Contrast and
- Color Saturation Easily", Jan/Feb 1990, page 34.
