Here is a cover of Family Computing (an 80's magazine that featured CoCo
programs in BASIC) that I scanned and ran through both MGI Photo Suite's
oil paint filter, then loaded into LVIEW and dithered down to 128
colors. You can see how the tarnished image improves with little
effort. I haven't tried it on higher detailed pages yet.
Another excellent option that would require way more effort is to use
Macromedia's FLASH software to vectorize the covers which would allow the
peeling away of yellowing, splotches, or other blemishes, as well as allow
the perfect resizing of the pages.
