Does anyone have experience with bleach bypass processing? I like the effect in movies, but have never tried it myself.

I'm presuming this is done at film development time, not paper development, but I have never seen any details, so I could be wrong. Also, is it applicable to slides and C-41?

Anyway, I'd love to read a discussion on this, or a pointer to more info. I did search and find a short note from Bjorke circa 2003, but it wasn't more than a quick summary of the film process.
