Dear all,

In any case the most important parameter for a scanner is the Optical Density
(Dmax) ( that is
the maximum density that you can obtain from an imagesize. This is not
exactly the same that resolution because you can be a high resolution (number
of pixels) but with low precision (Dmax). In short, the most important
feature for a scanner is the definition of the image. Another relevant
characteristics is that scanner have a flat design because the cores can be
scanned equally in all the lenght. In my modest opinion is not too much
important that the scanner must be A3. Obviously a A3 scanner permit a more
confortable work.

Considerations about operating system can be very important if you work to
high resolution with big images (over 40 MB). I love UNIX is incredible fast
and powerful ;-)
