Digital BW, The Print

I have put together a Web page with images of negatives under the 
microscope, compared with Minolta scan and finally a PiezoBW print.

Take a look and see if this aids our ongoing discussion regarding 
various medium format scanners and their respective interpretations 
of grain into 
pixel data.

Very interesting. Looks like no grain/grain-aliasing problem worth 
mentioning. But please explain:

How did you produce the Tri-X Pro negative images? I don't understand the 
relationship of the images to your explanation.

Thanks.

Victor,

I used an Intel (video) microscope to magnify and capture images of 
the negatives.
