I just tried out one of these C-41 home development kits for the first time, the CineStill 2-part kit, and one 1 of 6 rolls failed. I suspect the film itself was somehow defective, but would like to hear if anybody has alternative opinions or knows something about this particular stock.
The bad film was a Kodak Gold Plus 100, purchased in 2007 and stored at room temperature since. It was the only one of this batch that I developed, the other rolls were all different stock and newer. It came out 100% black (actually dark grey, still technically translucent). End to end, no sign of leader, no edge markings, no sign of any frames. The canister looked normal as far as I could tell.
The camera is known to be good, with good B&W rolls shot both immediately before and after. It was developed in a tank with 2 other rolls that came out fine, so changing bag is clearly good and chemicals were clearly good.
The only things I can think that would cause such even whole-roll failure is manufacturing failure, or somehow this CineStill kit isn't compatible with this particular roll? But my understanding is that C-41 is C-41 is C-41, so it shouldn't be a compatibility problem?
