Which developer would you use for developing Tmax 3200 (TMZ)? I have DDX and Xtol on hand and can get fairly easily Tmax developer (I actually have an unopened bottle but it is beyond it's "expiration" date)? Film was shot at EI 1600. Also which developer would you use for Delta 3200 (EI 1600)? I was leaning towards the DDX figuring Ilford knows best about it's film. BTW what is the shelf life of unopened DDX and Tmax developer? Both bottles (unopened) have been sitting on my shelf for 2 1/2 years. I have used opened bottles of DDX in the past beyond a year of opening them with good results. Thanks. Sincerely, Hany.
