Over the past couple weeks, I've noticed that my negatives becoming more and more dense. This morning I developed a roll of FP4 in Rodinal 1:50, cut back the development time to 12 minutes @68 (from the 15 minutes recommended by the Massive Development Chart) and reduced agitation, yet the negs still came out too dense. I'm using the last of a bottle of Rodinal that's probably three months old where the liquid has turned quite dark. A search on this site addresses the color question as harmless, but yields nothing on the potency question. Could this stuff be getting more intense?(posted 8249 days ago)Thanks...
