Hey Rob, when you leave the scanner lid open, try to keep the light in the room you're scanning in as low as you possibly can.
I think I still have the settings I sent to you previously if that will help you any. I have a different scanner but your scanner software should be pretty close to the same as mine. After you get the scan, the rest is on-line with photo-editing.
Let me know if you want the step-by-step sent again, or if it would be easier I'll pm you my phone # and I can go over it with you on the phone. Once you get the hang of three or four scans it's cake after that.
