This morning I ran off a series of shots to use as clip tests. And then developed short strips first in fresh Rodinal and then from the old bottle I had that had given me such poor results.. Using the recommendation that rjs003 gave I shook the bottle vigorously before mixing. It was as he stated the solution had separated and shaking recombined the elements,. The results showed equal activity They [the results] are no way an accurate measure of the film or developer normal results. But do show that the developer activity is fine. I was frankly surprised that shaking solved the problem or that liquid developers could separate like that. Thanks for the advice
