Hi there

As most of us I use my film developper "one shot" and toss it after processing. I occasionally reuse it for a second batch right after the first and the results are perfectly fine.
But I was wondering if this slightly exhausted chemical was any good for processing something less critical and more controlable by view like paper prints ?

Has anybody tried it ?
Maybe it could be added to more conventional paper dev to make it last longer ? What would be the effect on tones ?
My darkroom is not ready yet so I can't try rn...
