Re: Plustek scanner

IIRC, the difference is all in the software, but I've managed to forget the details in the year since I bought mine (I ended up buying the more expensive version).

One of the modern processes used in digital photography is known as HDR (high dynamic range) - basically the same picture is taken at several different exposures and then they are combined under an algorithm that knows how to choose the best from each exposure. This is a way of dealing with the fact that the same picture may have some areas that are very dark and others that are very bright, so it uses the over-exposed version to fill-in the dark areas and the under-exposed version to fill-in the bright areas. The version of the scanner I have has an option allowing you to specify two passes, which provides a simple version of HDR.

The software on my scanner also allows you to do during scanning a lot of the changes that might otherwise might be done in post processing (in Photoshop or GIMP) - cropping, adjusting overall brightness, adjusting brightness curve, etc.

However, I should also note that I had to disable some of the defect correction - apparently some reporting marks were "recognized" as scratches.
