TMX is a bit low in acutance, so I've found it very worthwhile to use D-76/ID-11 at the 1:3 dilution rather than 1:1. TMX in D-76/ID-11 gives a relatively straight-line curve shape of long-enough scale that if you were to actually use the entire straight-line section you'd exceed the range of any paper by about seven to eight stops.(posted 8537 days ago)Once you find a working time for ID-11 1:1, try it at 1:3 giving 1.5X the 1:1 time as a starting point.
