Originally posted by StiffLegged Kodak D76 and Ilford ID-11 are the same developer. Same recipe, same results.
This is 99.9% true, except that D76 comes premixed and thus Kodak uses agents to prevent oxidation and other issues vs. ID-11 that does not need it because it is not premixed, but comes with a part A and B.
Essentially they are interchangeable assuming the age of D76 is not too old or exposed to hot storage and that the ID-11 is well mixed.
Of all the general developers, I feel Kodak XTOL is a notch above both D76 and ID11. For Kodak TMax, I swear by Tmax developer and for Ilford Delta, DD-X, although I know the chems in XTOL and DD-X are essentially equivalent.
