[sane-devel] Missing greys

I've got a Canoscan Lide 50. I have discovered that when I scan at 150 dpi  
or more the greys are missing in depth (in the black end). But when I scan  
at only 75 dpi the result looks much better since darker and lighter  
pixels are mixed to show the right grey nuance. Is it possible to have  
this behaviour at higher resolutions as well and in that way "creating"  
those missing greys?
