Originally posted by MikeW There are numerous settings and options available with Vuescan. I would recommend setting some time aside and going through the reasonably decent manual that comes with the program. I haven't used the auto-detect function for edges yet. When I scan multiple images, i.e., slides, I set the crop border to a negative value so that the curve of the slide holder won't be included. Also, if you set a positive value on the buffer, it won't use edge data to modify the white balance. Good luck. Much like Photoshop, there is a learning curve to using it.
Just went through their website and found the user's guide. Thanks!
