DDX 1+9: Here are the specifics on DDX 1 part + 9 parts distilled water. New Delta 400 rated at 400, 72 degrees F for 10 minutes, rated at 800 - 12 minutes.30 secs. initial agitation, 1 inversion each minute (simply turn it over, then put it down).One roll in a 2 roll tank with enough developer to cover the one roll.(posted 8415 days ago)Divided D76: I've scanned the Delta 400 (rated at 400) I developed in Divided D76 (from The Darkroom Cookbook) and its really nice. This appears to be a useful method for controlling high contrast and may be good for general use as well.
I mix this by teaspoon measure. For a liter (or quart) of each part mix at 110 degrees F using distilled water: Part A is 1 tsp Metol, 6 tsp Sodium Sulfite. Part B is 6 tsp Sodium Sulfite, 1.25 tsp Borax. Develop for 5 minutes in Part A, pour that off (no stop or rinse) then pour in Part B give it 5 minutes in that. In both solutions I agitate for the first 30 secs. then once a minute. Let us hear how this works for you if you try it.
