Title: Epson 4990 scanner settings Post by: CHoffman on March 13, 2019, 04:46:56 PM Back when I used Profile Prism a lot, I had a different scanner. I decided to make some profiles recently and am having trouble with the IT-8 target image. New scanner is the Epson 4990. Tried about every combination of settings, but Profile Prism always reports the scan is under exposed and has poor illumination uniformity. In any editor, the scan looks great and the white square is just under 255, so it isn't underexposed. The light bar moves with the sensor, so I can't imagine how the uniformity could be bad. My target is old, but still looks great. I'm using the right change # for the target. Using 48 bit tiffs. Any ideas to try?
edit- Oh, never mind. The idiot wasn't positioning his corner markers correctly on the lower edge. I'm blaming it on daylight saving time. |
