I just received some prints back from the lab on Kodak Portra400VC and the blacks were very black, basically underexposed. I know how to run tests to find the appropriate ISO for transparencies and of course black and white, but how do I determine an ISO for color negative film when a pro lab is doing the processing and making adjustments during printing? Does anyone else shoot 400VC and rate it at a lower ISO, such as 250 or 200? Thanks
