I usually shoot with natural light when shooting with photo paper. In this video, I tried out shooting with 2 x 150W spiral fluorescent bulbs and processing it as a positive (Reversal). I also tried pre flashing the paper to see is there improvement in tones or reduction in exposure time.

****************************
Bleach Recipe : (read MSDS and observe all handling precaution!)
Bleach Part A
Potassium Permanganate 1 g to 250ml of water

Bleach Part B
Sodium Bisulfate 13.5 g to 250ml of water

Add Solution B to Solution A (always add acid to water) just before use as this bleach does not keep well once mixed. Discard after printing session.
