Hi.

I'm about to try out C-41 developing for the first time. For me the amount of film (rolls and sheets) will be small so chemistry longevity is an important thing to me.

I've read in at least one or two blogs that some people mix up a half batch and use 500ml at a time instead of the full 1000ml (1 quart kit size).

What I'm not clear on is, do you mix the entire batch of chemistry and then divide it into two separate working sets (one for now and one for much later) OR do you cut the kit solution in half and only "mix" one half and retain the other half un-mixed in the original bottles for later use?

Does anyone have experience with this stuff? Suggestions? My primary aim here is to stretch the lifespan of the chemistry not to get more cycles on it.

Thanks!!!

Adam
