John, i have had beautiful results with pushing delta 400. when exposed at 800, it prints and retains almost exact characteristics as when shot at 400. i use ID-11 (D-76) to process it. My normal for 400 is 11min, 15 sec @ 68f.. and 800 is 16min. 45 sec @ 68f. good luck, Sean.(posted 9079 days ago)
