The only trace of Paterson's new ascorbic-based FX-50 here in the US has been brief mention in Photokina reports. A visit to the Jessops site shows current UK retail availability. Has anyone over there tried it, and, if so, would you please share your results? My fantasy has FX-50 as an Xtol equivalent that performs consistently. Hope springs eternal! Thanks in advance.(posted 8667 days ago)
