When I select Image/Adjust Colors/Gamma, make my Adjustment with the slider, and hit OK, it just goes back to the way it was before I made the adjustment on the slider. I've tried doing it manually on a single file, and I've tried batch processing. I've tried saving the file (.tif extracted from a .pdf) as a .jpg and running it on the .jpg, to no avail.
I'm trying to gamma correct scanned sheet music so that a tiff-import feature on my notation software (Finale 2005) will recognize it as music. The original scans are pretty light, but the preview in thumbs seems to suggest that I could get it dark enough, if I could just get the change to apply
Any thoughts?
