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.

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

Frankly speaking.....:-) -- I process TXP in D-76 1:1 (homemade) for 7.5 minutes in my JOBO. Hope this helps.

From the Kodak Master Darkroom Dataguides 1972 & 1970 printings

1972 For Tri-X sheets with intermittent agitation at 1 minute intervals, large tanks, 68 degrees F: 11 minutes; For continuous agitation (trays), same temperature, 9 minutes.

1970 For Tri-X sheets with intermittent agitation at 1 minute intervals, large tanks, 68 degrees F: 9-1/2 minutes; For continuous agitation, same temp., 7-3/4 minutes.

Both datguides say to develop D-76 at 1:1 for the same time as Microdol-X straight up (undiluted), regardless of film.

Kodak's recommendations err on the side of overdevelopment, and through out the 70's, if I remember right, they just kept on increasing their recomended development times. I'd start off with the shorter of the two times suggested (1970 times).
