Ain't necessarily so.  Clairty is ranged by an actual formula and principle 
in physics defined by the circled of illumination or 'circle of confusion.' 
This has to do with the light passing through a lens to strike a film plane 
or chip sensor.

The question is a good one, and I'd like to know the answer, but before 
pixels can be recorded, the light muse register clearly on a plane of focus. 
My understanding created by my photo finishing person has lead me to 
understand that the scan size or file before printing makes for the clarity 
of an electronic print. (I hate using the term digital.)
