Also, here's a review of the Coolscan. It's very useful, but it's not true that ICE technology doesn't work with Kodachrome slides. I'm not sure where the reviewer got this idea. The slides below are Kodachromes. Possibly Kodachrome slides from the 90's don't work, but ones from the 80's and before work, plus every other slide I've tried. Black and white negatives are not subject to ICE, though. That part is true. (Kodacolor negatives do work, though.)
Here's an example of an initial slide scan without I.C.E. Dust Removal activated, and nothing else done to it.
Here's what the scan looks like with the ICE activated. Nothing else has been done to the slide.
This is what the slide looks like with grain diminishing and color restoration (for faded older slides) added. I normally don't add these, but I thought I'd show you what they look like. Note that the grime streaks on the slide visible in the clouds are enhanced through this process.
Below is an example of how things would look using the Photoshop Elements software. I normally adjust every slide with this software, at least a little. It's the greatest bargain on the planet at only $49 from Costco (after rebate) because Photoshop 7, the best photo processing software (a more comprehensive version of Elements) costs over $500. However, Photoshop 5 is bundled with the Nikon Coolscan IV, so you can use it. But Photoshop Elements is very easy to work with, and it includes improvements over Photoshop 5. Actually, Photoshop Elements 2 is the new version, and it is by all accounts even better than Photoshop Elements. We've purchased it recently, but I haven't installed it. If you want to borrow this version of Photoshop Elements and install it on your computer, that's certainly fine.
