Can't lower "detect above noise level" any more.
I am loading 16-bit Tiffs (287 MB each, from Canon 5dsr) into APP but continue to get this message when I get to registration step. I have lowered the "detect above noise level" as far as it will go. I am not using any calibration frames, just lights.
I have successfully run this type file in APP before.
What do I need to do?
