So I'm currently running Ilford chemicals for both film and paper (although I'm using Kodak's Photoflo).
At the moment, I'm only mixing what I need. For instance, if I'm doing some printing. I mix up a tray's worth of developer, stop and fix. And squeeze as much air out of my bottles as possible.
Once I'm done printing, I throw out the chemicals in those trays. I've always been under the impression that the undiluted, straight-from-the-factory chemicals have a longer shelf life than if I mixed up a big batch of chemicals and stored those. My method also cuts down on the number of random bottles I have laying around.
Am I right in assuming this? The only downside I can see to the way I do it is that I have to mix chemicals every time I want to develop or print.
I also use my chemicals as "one shot" because I just don't go through them fast enough for it to matter.
