Response to Anybody used Paterson FX-50 yet?

There are several other ascorbic acid based negative developers on the market that seem to work fine. One is Tetenal Negafin, about which I have not seen any negative comments concerning failures. The Tetenal product should be available in the US. I have not used it, but the reviews in the European photo journals were excellent and it has become one of the standard developers here. Also Foma markets a ascorbic acid developer under the name EXCEL, which probably is not available in the US, but can be ordered through Fotoimpex in Berlin. I have used Foma EXCEL with very good results. It is made in Poland by Foton, a formerly independent photochemical company that was purchased not too long ago by Bochemie, the owner of Foma. You might want to consider one of these two products as an alternative to XTOL.
