Hey all, I was wondering if anyone had any information on how long I can leave my mixed chemicals out in the open air. I have a jobo cpe2 and mixed up the chemicals to develop a few rolls of film 2 days ago. They have been sitting in the graduated cylinders open to the air since then. Any idea if they are still good? Should any extra developing time be needed if they are, (I have run 4 rolls with the developer x-pros)? Also, might be a dumb question but any foreseen problems developing regular slide film after using the chemicals for x-prossing with the added open air expossure? All help is welcome, I am about to try it out anyways to see but if I get a response soon it might save a couple rolls of provia Thanks!
