I've got some rolls of color in the fridge that I'd like to shoot and develop as B&W. I think I've read that it's possible. I've got random type rolls. Is there a general rule of thumb as I'll obviously not find straight formulas for such unorthodox method. Would stand developing in Rodinal be relatively foolproof?

(yes, I can develop them normally and convert to B&W in PS, but that's not my question).

Thanks.
 
When you process c41 in B&W chemicals you'll end up with really low contrast
negative with an orange mask. Start with the equivalent asa/iso (400 to tri-x) for development times and temps. Also that orange mask is going to make printing really difficult.

Not necessarily so as this previous post of mine demonstrates. Given correct exposure, there can be no noticeable difference. My C-41 negs scan fine on my V500.

YMMV.
 
Thanks a lot. I'll go with the Tri-X times advice.

I prefer to shoot in B&W. Those color rolls are some odd lo-fi mostly expired rolls that somehow made way into my fridge and haven't been given away yet. I don't like to throw film away so I'll just shoot some odd frames on them, certainly nothing remotely important.
 
Filmtwit, I developed that in Rodinal 1:100. The output is the same. Both develop in B&W chemicals the same way. The only difference is down to the film grain and brand.
 
Ya still end up with that orange base and tends to cause problems when you try and make prints from it.
