Cross-processing, briefly, is a photographic technique where (usually) slide film (E6) is processed in the set of chemicals usually used to process print film (C41). (Less common is cross-processing in the other direction -- print film processed in slide film chemicals) The result is images with oddly skewed colors and increased contrast and saturation.
The problem we're running into now, however, is that this process depends on shooting with film. What happens if you're one of the photographers who have made the jump to digital?
Well, for those who use the digital like me, and like this technique, I created the Cross-Processing Action. I hope you enjoy it, as much as I do
