I am running PI 01.08.05.1353 and have tried to run the CanonBandingReduction script several time and have given up. It locks up or takes too long to run... I am trying to correct an Integrated Stacked Image from a T3i. After ~2 hours I have to kill the script. Task Manager / Resource Manager shows PI is working on something.
I am running PI on a Core i7 Lenovo E440 laptop with 16GBytes of memory, 512GByte SSD and 128GByte M.2 card. The CPU is saturated.
