Pan F requires 8.5 minutes while Delta requires 12, according to the chart with D76 1:1. I've done Pan F with 10 minutes with good results, but If I bring it up to 12(to "please" the Delta), will it be damaged or just super high contrast? Is there an acceptable compromise between the two? Both rolls are of rainey night shots in the city - wet pavement reflecting lights/Christmas lights/cars zooming by/etc. Or, should one NEVER EVER attempt such a thing? I'm trying to kill two birds with one stone - since my time slot allows for just one roll/set to be developed.
