you soon get an instinct for what size...
Exactly! All my scans are made outside of SCF. Instinct and experience say covers at 100dpi, items the size of business cards at 200dpi, and stamps at 300dpi. Seldom do I ever have to adjust the image due to excessive file size, but when I do it's opened in a photo processing software for a quick fix. If I need the image for another use, I scan at a higher resolution at the same time.
