Not sure if this is the right venue.

I would like to know if anyone have tried to cross process kodak 400 CN chromatic film (process as E6). And if so, what are the requirements, i.e., does the film needs to be pushed. The film was exposed at 400 ISO.

A decade ago, i use to have Ilford black and white chromatic film (I think it was the XP2 film) cross processed and it produced beautiful monochromatic slides. I remenbered pushing the film was involved, but can't exactly remember how much it was pushed.

Any input would be much appreciated
