Process Kodacolor-X as Black & White

I recently shot with an old Carlton 127 camera. The only film I had was a roll of new-old stock Kodacolor-X.

Kodacolor-X is process C-22 film, extinct except for a couple of specialty labs who mix their own chemicals from scratch. Since I shot the film (not a precious roll of family photos found in a relative’s attic), it’s not worth the price or the wait to send it off. I’ve read here and there about cross-processing old color print film in B&W chemicals and even had some success (-ish) with Kodachrome. Worth a shot so here’s what I did:

I used Kodak HC-110 developer at dilution H. H is an unofficial mix using 1 part developer concentrate to 63 parts water. That’s the US strength developer where dilution B is 1+31.

I used a Yankee plastic tank and lower reel that can adjust for 127 film. For 127, the tank takes 420mL of solution.

Everything was done at 20C/68F. I developed for 10 minutes agitating the first 15 seconds (about 10 inversions) and then 4 inversions every minute for the remainder of the time.

One minute stop bath, using Kodak Indicator Stop at 16mL/liter, inverting the first 15 seconds (10 inversions) and then letting it sit for the remainder of the time.

Ilford Rapid fixer mixed to normal film strength (1+4) for 5 minutes using the same agitation as the developer.

I rinsed using the Ilford method: fill tank & invert 5X; Re-fill & invert 10X; Re-fill & invert 20X. I gave it an extra 20X rinse with some Photo-Flo for good measure and hung it to dry.

The base is really dark orange but Kodacolor-X doesn’t have the nasty, black anti-halation layer that Kodachrome has, and it scanned OK. Boosting the gain on the scanner brings out the noise and grain, but not too bad for what I was working with. I used VueScan software. The Canon software won’t do negatives without the film holder but I don’t have a 127 holder.

I’ll try scanning again after trying a bleaching step, soaking the film in fixer with ascorbic acid (vitamin C) added.

Kodacolor negative.
