So, I had 2 rolls of this stuff: I saw "for color slides" and thought oh yes, I'm going to cross-process this and it will be all colour-shifty and everything. Turns out that "CT18" refers to a long-obsolete colour process. I didn't know that. Turns out, cross-processing CT18 film in normal c41 chemicals at normal c41 temperatures will absolutely result in a completely blank set of negatives. I didn't know that either, but looking at a completely blank set of negatives I do now. Bugger. Also, after putting 2 rolls through my cheapo action sampler and processing today, I've yet to get anywhere close to a well exposed image. Bugger bugger bugger. Today has not been a good day.
