![]() ![]() The Dimage Scan Elite produced scans that were slightly sharper than those from the other lower-resolution scanners, but we had to look very hard to find the differences here, too. We found surprisingly little difference in the amount of detail revealed by the 2,438-ppi Dimage Scan Dual and the 2,900-ppi Coolscan. The Super Coolscan produced sharper scans than the ArtixScan and SprintScan, and the CanoScan was the least sharp (though the differences were slight). We found that the 4,000-ppi scanners captured more detail than the lower-resolution models rather than simply creating a larger file, but we also found that they were merciless regarding flaws in the original images–chromatic aberrations in lenses and softness due to camera shake are much more obvious at high resolutions.
