Hi Don:

You and Richard are hitting on a key drawback with the DSLR/copy stand method -- "provided you get 
the lighting right."

I think it's unrealistic to expect the typical multi-tasking archivist or librarian or worker bee at 
a record company to "get the lighting right" or perfect using the copy stand, or for that matter 
figure out a typical "feature"-bloated DSLR camera. Flatbed scanning is easier to master and fits a 
typical office logistic and workflow better. Plus, Don said below, the best you can do with that 
Sony camera is 250dpi. My scanner goes higher than 600dpi, but 300dpi is what I typically use for LP 
covers. Plus, my scanner has a built-in de-screener that works very well on old printed photos 
typical of album covers.

Also, what does one do with things like a hardcover book or a big equipment manual with a photo 
stand? On a scanner, one can squish it flat pretty well (although BEWARE, I've heard tales of 
breaking the scanner glass if you get too enthusiastic about squishing things flat -- much better to 
get a de-binded copy if you can obtain one).
