we all carefully prepared negs and slides before printing or copying, using an antistaic device and a fine brush to remove all traces of dust - but I confess to seeing few if any people ever do this when scanning..
And after that, spend half an hour or so doing dust spotting on the
scan. And *old* slides or color negatives are generally not in
pristine shape.
the resolution seems to be OK on DSLR's for people to take pictures, many arguing that even in the 6Mp days, there was/is more detail available as a digital original than a film original (I have always disagreed) -
You need a lot more scanned pixels than digital-original pixels to get
the same printable image size; presumably because the original pixels
are much cleaner.
And RAW supposedly has the dynamic range .. certainly more range than E6 film captured anyway even though the contrast ratio in the slide may be higher..
The issue isn't the scene, it's the slide itself.
and now camera RAW's can be imported into Vuescan for the benefit of decent film image cleanup
Hmmm, haven't worked with Vuescan, but ICE works via an infrared scan
channel, so you can't duplicate the results outside the scanner.
