Due to developer freshness and storage. I think I'll need about 50 ml Xtol stock per film. Filling 100 little 50ml bottles seems overkill. As an alternative, I could use several larger bottles to keep the number of total bottles within limits. But the foresight to redistribute the larger quantities into smaller quantities as needed is very unattractive. Hence my search for a Xtol alternative that can be combined with a Rodinal like developer for stand development. So far I found two alternatives, the mentioned HRX-3 and Fomadon Excel. I've read raving reviews of HRX-3 and it has the advantage that is a liquid developer with a shelf life of two years. On the other hand, Excel is a powder developer that is distributed in 1L packages, a volume that is manageable using little bottles.
But, please, don't get me wrong, I am open for suggestions, ideas and tips!
