The "dandruff" could be noise but it is more likely film grain - it is
generally most noticeable in areas of similar color such as skies. If it is
grain, upgrading will not help, but Vuescan's grain reduction filter should -
try it and see.
To upgrade to some kind of ICE, would cost $500 and up - the Scanwit 2740 has
it, all the Nikon scanners, Polaroid has its own version and a number of the
Minolta scanners have it.
It is very useful IMHO - I have the Nikon LS-30 and use it consistently.

| Hi folks -
|
| Only slightly less of a newbie now, I continue to study Mr. Fulton's
| superlative scanning tips book, and experiment with my scanner and
| software. A few weeks into FS2710/Vuescan ownership, all this
| learning is, I think, making me aware of a couple of this scanner's
| shortcomings, but I want to ask about one of them. The other is
| straightforward, the lack of batch scanning capability.
|
| But the question has to do with shadow noise, especially on Velvia
| slides. Since I'm new to "high res" scanning, I'm not entirely sure
| what I'm looking for. On some slides that I scan that have large
| areas of shadow, I see something that looks like dandruff scattered
| more or less evenly across the area. Is that what shadow noise looks
| like? Are there various forms of it?
|
| Combining the two questions with one more - how expensive a scanner
| would I have to upgrade to in order to have better shadow "silence,"
| batch scanning, and some kind of ICE?
|
| I have on emore question, but I'll post it seperately.
