Dear Ryuji, Thanks for the detailed reply. I am surprised at your comments regarding TX and HC-110. Using "B" dilution and Picker's (Zone VI) method for determining film speed/developing time, I get incredibly fine grain. ( My ASA is around 250 and developing time a tad under 5 minutes.) I originally tried that combo ages ago based on a talk Ansel Adams gave during which he touted that combination highly for 35 mm. (I'm using it in medium format, mostly.) Thanks again for all the information! Howard(posted 8223 days ago)
