JOOC, what does PGI stand for?
"Print Graininess Index". Kodak observed that their films compare bad with other manufacturers when the grain is measured using the standard "RMS" method. So they decided to stop publishing RMS data and replace it with their own PGI measurement. Nobody knows how this PGI relates to RMS. So you can't anymore compare Kodak data with other manufacturers data. See ? Problems have simple solutions.
