I've never tried photographing slides with a digicam, but given that a film
scanner uses a linear sensor while a camera uses a 2D sensor with Bayer
interpolation, the camera is bound to do an inferior job. The noise level
will also be much higher in the digicam--they typically only have about six
bits of S/N ratio.

However, my experience is that scanning large numbers of slides without
automated equipment isn't worth doing, unless you're in prison and your time
isn't worth anything. ;-)

My advice is to either to scan only those slides you actually want to print,
or pay someone else to scan your slides with automated equipment. I've had
reasonably good results on most images with Kodak PhotoCDs (not PictureCDs).
