Comments:  I give 30 seconds initial agitation, followed by 5 seconds agitation (2 inversions) every 30 seconds.  This time is for a diffusion enlarger.

Comments:  I process in a tray with constant agitation (gentle rocking).  I use a  random agitation method.  Back to front, then side to side, followed by back right corner and finally back left corner and then repeat the cycle throughout the developement.

* Using the standard single bath method (20ml A + 20ml B + 260ml water). EI and times were arrived at by measuring with a color densitometer with Zone I to be between 0.10 - 0.15 and Zone VIII to be 1.30 - 1.35.

 **To counteract the oxidation, I use a little more A (6ml A + 10ml B + 500ml water instead of 5ml A) and always mix a half liter per roll. EI and times were arrived at by measuring with a color densitometer using only the blue channel for measurement. I fixed Zone I to be between 0.10 - 0.15 and Zone VIII to be 1.30 - 1.35.
