I tried it, following some recommendations I found on the web in an article by Patrick Dignan. The developer he recommended was FX-2, a metol/glycin formula. I seem to recall diluting it 1:1 and developing for one hour with a one minute agitation up front. I don't remember what film I used, but the experiment was not a success. There was no gradation in the high values (which is what I was after), the middle values were weak, and the shadows were non- existent. I don't recall the EI, but I always test at 50% of the manufacturer's rated speed.(posted 8877 days ago)However, recently I developed some 8x10 sheet film, shot with a pinhole, in Sandy King's Pyrocat-HD formula using a semi-stand development (one minute at the beginning and one minute in the middle). Development time was 21 minutes. These negatives are perfectly printable, but next time I will dilute the developer even further and develop longer. I tried the same thing with PMK and it worked just fine--no uneven development
