I have a kit that's been partially used, sitting on the shelf for a while and the developer died. The bleach and fix are still good. Since the dev is basically a B&W dev, are there any print developers that give good results? I know there has been some formula info posted here, but I've never really been a mix it from scratch kind. In order to salvage the remainder of the kit, I would like to find developers that give good results. Any one with experience using existing B&W dev, and what adjustments, if any are needed?
