Grain aliasing is also an issue; Certain films will appear to have
significantly larger grain when scanned due to interference between
the discreet nature of the silver grains and the scanner sensor.
Chromogenic film doesn't have sharp edged film grains to cause this
problem. For scanning, the lack of acutance of the chromogenic films
is an asset.
