Kate40: Welcome to Bellazon! It's great to see more Stephanie Seymour fans. (And I noticed you also mentioned a fondness for Joan Severance, which I certainly share. What I want to know is, Who was Miss Houston that year?!?!)
Your scans looked fine.
If you do want more information, or some scan tips, try this site: http://www.scantips.com/ . The site typically uses lots of examples, and the site is usually clearly written.
This is a useful page, also: http://www.scantips.com/basics06.html
Digital imaging is one of those things that you may have to spend some time reading (and re-reading, and re-reading) and experimenting with and being frustrated by. That would accurately describe my experience, anyway.
But your scans looked fine. And welcome to Bellazon!
