I was delighted with the performance of my home-made XTOL (MYTOL) - but not delighted with the same old D76 deterioration on the shelf and the mixing of large stock solutions with limited capacity. So I just tried PC-TEA hoping to get the same performance I was getting with MYTOL but with the convenience of a 50:1 stock solution with unlimited shelf life. My first try using 400ml TEA at 250 F 45g Ascorbic Acid 1.25g Phenidone last 100ml TEA 50:1 at 68 F was TRI-X pushed to 1600. 14 minutes with 5 sec agitation every 30 sec. All my shadow detail is there and the film looks great - I will soon know if the grain is tight and by looking at it, it doesn't seem to have that N+2 look I was expecting and half hoping for - I may try a three stop push if it doesn't have the contrast expansion I was looking for. (Dusk shots with very low contrast) Should I add Benzotriazole or Potassium Bromide? I don't seem to have any streaking or fogging now but I will certainly be using this for FP4 (if it can be purchased ... ) and other films as well. I am also hoping the grain will be as fine as the MYTOL I was using - (which had some sulfite in it) I would like microdol fineness with acufine speed ... with pyro accutance - throw in the moon and stars and I will not have to experiment for at least a few weeks! Any advise from the pros would be very appreciated!
