Using Epson 4990 scanner. Gimp with Xsane plugin. Scanning a 1940s 5x7 negative. Settings- transparancy unit, gray scale, full color range, 75 dpi (same effect with any dpi), either auto adjust or default settings (same effect). The image shown is an example of how my scans come out. What is my problem? This is simply a b&w negative showing a well dressed couple.
I have read that xsane is troublesome. Could Xsane be the whole problem?
