Please learn the meaning of words before using them - there is a vast 
difference between "theoretical dogma" and the science of optics which 
has been practiced, honed and refined for over 400years and is currently 
one of the most, if not THE MOST, well defined and understood of all of 
the physical sciences with NO KNOWN deviation between theory and 
practice!  All that differentiates practical imaging systems is how far 
short of the theoretical performance they fall and in what aspect.  In 
the aspect of resolution, that shortfall is virtually all defined in the 
MTF curves of the various system components.

As I stated in my first response to your posting:
"Why assume that the only difference between your prints is the 
resolution they were scanned at?"

You should note I did NOT suggest the difference was due to the scanner! 
However I am certain it was NOT due to the resolution at which they were 
scanned, since there is insufficient resolvable detail on film at that 
resolution to create the substantial difference you cite.  That has 
nothing to do with dogma - only understanding the science behind the 
image formation.

In addition to learning a little of that science, you would do well to 
read what is written.  Clearly the operator either didn't have the skill 
or the facilities to match the MTF of the desktop scanner to the 
sampling density - a function which is readily controllable on many drum 
systems.  If he had then you would not have posted about the clearly 
visible paradox that a scan capable of resolving MORE grain actually 
produced LESS on the final image!
