How old is the scanner? Dust in scanners will create this effect. I went through a hundred relatively bad scans until I realized that what seemed like slow deterioration in the scan was actually accumulating dust. It can happen so slowly that you don't realize it's getting worse, because you forget how clean the scans originally were.

When I scan a slide (either Kodachrome or Provia/35mm), the white areas (such as a building illuminated by the sun; or pages of an open book) in the scan will exhibit a "halo" effect. This appears as a kind of a whitish or even greenish glow surrounding the white object in the scan. My questions are: Is anyone else seeing this or getting this effect on their scans? Is this something gone wrong with the scanner? Is it something that different scan settings in Vuescan can correct? Using Knockout 2.0 I can correct most if not all of the "halo" or "after glow." However, if someone can set me straight regarding how to solve the problem before the scan, I would be most appreciative.
