Would anyone have a reciprocity failure chart for Bergger Pancro 400 film. Bergger's datasheet for the film on their website only has correction information for 1s, 10s and 60s. I was looking a wider range especially between 10s and 60s. I don't think a liner interpolation of the time between 10s and 60s would be accurate.
The only reciprocity failure app that lists the Pancro400 is for the Android, I can't seem to find any for the iPhone.
This is the information on Bergger's website.
