The thing is I don't want to replace anything as that would take away from the original context of the book. Since this is a preservation I believe the book images should be presented as they are. If anything the brightness, color balance etc, needs to be adjusted accordingly for each image.
I agree completely. That's why I didn't get the idea of taking some screenshots to replace the photos at all earlier. But please continue with the good work!
