Hi Alan,
You have heard of
www.scantips.com, right? You'll get a lot of great tips at that site. Plus the newsgroups that Greg mentioned.
I have a Minolta Scan Elite (2820 dpi tops) with ICE and love it. I always scan with ICE on - saves me from major cleanup work and I don't notice the fuzziness as some people claim to. Perhaps it is different with different scanners though?
I find the Minolta does pretty well at getting the correct hue for slides, but not so well for negatives. I usually choose to color correct in
PS rather than the scanner software because I feel I have more control over that in
PS. However, I do correct for brightness as much as possible during the scanning phase - sometimes scanning both to bring out the shadow details and scanning a second time to bring out the highlight details - then combining the two photos in
PS when there is a lot of contrast in the photo. I have never been happy with an image straight from the scanner - I always do some sort of meddling in
PS. (BTW, don't use the scanner sharpening feature if you plan on editing after the scan - sharpening should be the last thing that you do in any image manipulation.)
As far as scanning resolution, like Greg said, it depends on what you want to do with the image. If you think you'll ever want to print larger than 8x10", then you'll want to scan at higher than 2700 dpi. Otherwise, 2700 dpi should be fine. (I'm wishing I had the capability to scan at 4000 dpi so that I could print larger images to frame and hang on my walls.) Sure you could use GF to enlarge a photo scanned at lower resolution, but you won't get as good a result as scanning directly from the slide/negative where the original information is.
Of course, the higher dpi you scan at, the larger the resulting image and the slower the processing in
PS (or any other program) since there are more pixels to "massage" with every edit that's applied. Plus, if you work with layers, remember that the file size grows
very quickly with each new layer added.
Hope this helps some,
Jeanie
