Hi Julian,

I believe he is specifically talking about when you downsample the image,
and the results you get from downsampling...  That, of course, if very
downsample algorithm dependant, as well as how your scanner handles scanning
at lower resolution.

This is one of those things that, in my opinion, is best to simply try out
on your system and see what works best for you.

Regards,

Austin
