D-76 and ID-11 developing times

[lsaavedra]

I know this question is been asked before but none of the responses

is the one I want. I would like to know why these two developers have

the same processing times for some films and different ones for other

(according to Ilford data spec). I shoot almost exclusively Ilford

films (pan F, FP4 and HP5) and I use D-76 due to make up convenience

and diluted 1:1 due to one shot use convenience. If I follow the

ilford recomendations for D-76 (different times than for ID-11) am I

doing anything wrong? Should I use the times given for ID-11

developer even if I use D-76? Thanks in advance

I forgot to mention that is my understanding that these two chemicals are virtually the same.

I use Ilford's recommendations for D76 less about 20% and my HP5 looks fine. You have to tailor your film processing to what suits your taste in negatives. There is nothing wrong with modifying what is recommended by the chemical or film maker.

Possibly because they are similar developers but not exactly the same. What most folks don't know is that ID-11 is uses the original D-76 formulation, while today's D-76 does not. The way to get the results you want is only achievable by doing your own testing. Published times are only recommended starting points. Your results may be entirely different.
