Although I usually shoot 4x5 Ilford Delta 400 developed 1-3 in XTOL, I want to try TXP 4X5 (320 ISO) developed in ID-11/D-76 with a 1-1 dilution. I used this combination years ago when I was shooting medium format, but don't remember the times. Most of my work is environmental portraiture, with 25% done w/available light, and 75% by studio flash.(posted 8650 days ago)The Massive Developing chart justs lists times for tray processing (I use a tank), and Kokak shows no time for ID-11/D-76 with 1-1 dilution. Their times listed are only for full strength. Any suggestion as a 1-1 dilution starting time with these developers and this film, and any comment on reslts would be greatly appreciated. Or is there a reason for using these developers only at full strength with TXP? Thanking you in advance, Burtnett
