Feeling Positive

This is a scan of a 4x5 black and white slide that I just processed.

 

The process is not too complicated. It's based on the Ilford Reversal Processing datasheet, and is essentially:

- First developer (Paper developer with some fixer crystals to thin the negative)

- Wash

- Bleach (Potassium Permanganate and Sulfuric Acid)

- Wash

- Clearing Agent (Potassium Metabsulfite)

- Wash

- Re-expose the film to light

- Final development and fix (normal chemicals)

 

I'm not that pleased with the final quality from this slide. I don't think I bleached for long enough, leading to some solarization at the top of the negative. The first developer time was also too long, even though I used a diluted developer formula and took 2 minutes off of the Ilford recommended times. Next time, I'll have to stop the first dev even sooner.

Here is the exact same shot, only processed as a negative using normal black and white film development.
