[filmscanners] Re: Bug fixes for Minolta DiMAGE Scan Elite II



The Elite is supposed to have better response in the shadows than the
Dual II as a result of the higher bit depth A/D conversion.

When you speak of the dark areas of the neg, do you mean the areas which
are dark in the positive result, or do you mean the areas that end up
light on the positive which are denser on the neg?

I think what you are seeing is a result of the speed of the scanner,
which in effect might be underexposing the CCD element and then attempt
to correct it by boosting the "gain".

If you have access to Vuescan, try the slow scan mode (as opposed to the
multiscan, which seems to help it very little) and see if you are
happier with it.

On the Dual II scanners I've seen, the blue channel is very noisy and it
creates a bunch of yellow artifacts in the deeper shadows.  Take a look
at the channels individually (you might have to play with levels to see
them clearly).  On the output of Dual II scanners I've seen, including
my own, the shadows look reasonable on the R and G channel but the blue
is a minor disaster.

Let me know what you determine on the one you are looking over.

And yes, the Minolta scanners do seem to suffer from grain aliasing
making the scans grainier than needbe.
