>>3712489Done that, CMS20 is okay but hard to use. Copex Rapid was best in Perfection XR and it’s better. Best compromise is Rollei 80s at 25-50 in a normal dev like Rodinal or Xtol.
I’ve used Kodak Vision SO print film, which is kinda like low colour document film, it’s made for printing negs, janky colour though, ideally you’d need to shoot through a CTO conversion filter since it’s made for tungsten light on top of a filter made from colour neg base (or just another CTO since that’s close) to colour balance decently. Lost all my shot though when other guy from dark room changed keys snd I could never get my stuff when he wanted to remove all colour stuff from dark room and left it outside on shelving where other people would have nicked it, I had stacks of panalure paper too he would have kept and assumed was his, all my chemistry and other shit.
Ektar is nice and I did shoot 6x7cm, but just that extra bit would be nice.
I don’t think it’d be a big tweak to design, same exact process, dye sensitisation, dye couplers, same amounts etc, same emulsion maybe just processed at a lower temperature to make much smaller grains that are less sensitive, maybe a slightly thinner pour with more coupler to help with extra crispness. Though they’d have to adjust developer inhibitor reaction chemicals so it develops normally at the same dev time and stuff.
It’d be a nice novelty and I’d use it for landscapes.

Actually I did several years ago maybe 2015 or 2016 acquire a lot of Panatomic-X and Ektar 25, expired, neither had any base fogging, Ektar 25 didn’t have any great colour just eh, grainier than Ektar 100 and wasn’t sharp (possible film did degrade and break down. That’s described happening with Ektar 25). Panatomic-X, no matter what I did I couldn’t get more than 40 lp/mm
