Hi All, I'll keep it brief, My Minolta XGM (1982) has underexposed a new, ISO 200 36 exp. Kodacolor roll (it's first roll in 10 years), 100% consistently - by around 1 stop. Film technology presumably has improved and as such 200 ISO is the new 100? I'm considering setting the ISO to 100 on the device, as this will likely resolve the issue. Guidance?
