Originally posted by Ben Hunt I'm not sure how the lab developed it but the next rolls I'm thinking of doing the developing myself or finding a lab that's able to do a stand development for an old film with a +1 stop push.
Unlike processing for standard B&W films, C41 has a standard chemical and standard processing times. To my knowledge there is no “stand processing” for C41. Have you seen the negatives yet, or just the scans? If you haven’t seen the negatives yet, check them. They may look underexposed (“thin”), then the lab scanning software tries to compensate resulting in a very grainy scan. The solution would be to overexpose then use standard developing. Shooting it at 200 or 100, might get it back to normal.
It is possible to process it as B&W, not C41, and that may work. I’ve seen people develope XP2 and B&W and it came out nice. But it will arguably look very different from BW400CN normally since you’re retaining the silver and not activating the dyes.
EDIT: I forgot to add that there are labs that do push or pull processing for C41. thedarkroom.com is one. But it’s different from stand development.
