Hi Richard, I like Agfapan 400 (EI 320)in Rodinal 1+50 and cut down on the apparent grain with GENTLE agitation. After initially banging the developing tank several times to eliminate bubbles, tilt the tank about 45 degrees SLOWLY about once per second or one and a half seconds. DO NOT INVERT. This should give less apparent grain than Tri-X in D76 1+1, or TMax 400 in TMax. Also, I find the grain pattern unobtrusive in character.(posted 8735 days ago)
