My standard way to mix my fixer (TF-4) is to mix up the ammount that I needed for my 4x5 processing, which is 1200ml that would be re-use multiple times (in batches of 6 negatives each time).
Now that I'm throwing rotary processing 8x10 into the mix, it only calls for around 300ml of solution with the way I'm processing them. What would be the best way to re-use my solution for both formats when I'm only using a part of my entire mixture for the 8x10 developing? Would I use the 300ml for 8x10, then mix it back into the remaining 900ml, and mark off a single sheet of 8x10 of usage? And then go back and use the entire (some of it partially used) 1200ml when it comes time to develop a batch of 4x5 sheets?
My guess is that this will be ok, since the more depleted fixer will be mixed back into the less depleted, it'll even out just as if I used the entire batch of fixer on a single 8x10 sheet. Is this correct? Or is this not wise?
