I'm just getting started with XTOL. Just now I'm using it straight (no dilution). According to Kodak, a liter of the undiluted stuff can be used five times without any time adjustment in development, and after five uses they suggest increasing the time by specified percentages.(posted 9043 days ago)I filled a liter bottle and have used it a total of four times. Wow! The stuff has gone from clear to opaque and there's a heavy deposit of silvery gray in the bottom of the bottle. To me, it looks like the end of the road for that particular soup.
As an economy, it would be nice to re-use developer, but I don't want to sacrifice quality of result. It also occurs to me that the diluted stuff might work better.
Has anyone out there had experience (good or bad) with re-using XTOL? Or with comparing the results of diluted vs. undiluted XTOL?
In case it's relevant, I'll add that mostly I use Tri-X, Plus X and Vericrome. Occassionaly (very), T-Max.
