Re: filmscanners: Magnification of light

Marvin:  I hope this responds to what your questions.  I scanned an old
Kodachrome slide I took at the Grand Canyon  and it had a section that was in
deep shadow, but you could still see some of the detail in the shadow.  I
scanned it on my LS-30, moved it to PS 5 and the manipulation took away the
shadow and pulled up the details.

By the way, Vuescan's ICE cleaned up the Kodachrome's dust and a scratch
