Hi, is there some spirial+tank system for processing 16mm C41 100' rolls. Anyone tried it ?
I've processed 100s of rolls of B&W stills negs and RA4 prints is movie film any harder ( bet drying can be a problem ) .

What 16mm film are you processing in C-41? Remember, motion-picture negative films designed for the ECN-2 process have a carbon black rem-jet backing that needs to be removed properly, or it could contaminate the film and process with rem-jet particles.

Ah, I guessed it was C41 as it's neg. Can you buy ECN-2 chemicals in home use kits?

Because of the need for proper rem-jet removal, the ECN-2 process is not easily run at home. Here are the Kodak processing manuals and kits (intended and sized primarily for commercial lab use):

..a good place to start:

I use a LOMO tank for processing Black and White reversal films as negative. You can find reversal kits for both E6 and B&W, but I don't like to bother with the bleach and I telecine most of my work rather than project.
This technique is great for acheiving a *look*. The LOMO tanks can handle 100ft of film for 8,16 and 35.

As John said, the crux with color negative MP film is the rim-jet backing removal. I suppose you could try cross processing reversal films with C41? That might produce an interesting look....

EDIT:
here is an example of super 8 B&W reversal hand processed in a LOMO as a negative in D76 without agitation for (.5 hrs) then telecined on a "Rank" machine:

There are some Tetenal C-41 kits that only use a few baths. I guess these may be practical to develop ECN-2.

Of course the anti-halination backing is still an issue.
