I've recently had some problems shooting P/N 55 outdoors in 28 - 35 degree F tem peratures. I shoot P/N for the positive, and rate it at EI 80. I usually take an incident meter reading, and use that as my starting point. The P/N 55 prints are coming out either real muddy (particularly if a polarizer is used) or somet imes they are dramatically overexposed suggesting I should rate the P/N 55 at so mething closer to EI 200. The negs look OK. I use the negs for focus check, an d then trash them. For the processing, I either put the exposed sheet inside my jacket, or inside my auto if it's nearby. It's gotten to the point where I jus t can't trust the P/N 55 material for exposure tuning. My chromes are exposing properly based on reading from my meter, so I know my meter is OK. As a control , I've taken sheets from the same batch and shot them indoors, and the prints lo ok great. I know your suppose to compensate development time based on temperatu re, but this is going way beyond that. Anyone have a theory about what is going on?
