In examining radiographs of various objects from archaeological
materials to architectural metals I have often found that the film
captures significant details that can be only seen through a
binocular microscope, and I have documented these micro-features via
photomicrography. Does scanning allow this degree of resolution? At
what magnification limit will pixelation pose a problem?

Also, do the new digital industrial x-ray units possess the same
resolution and clarity that film has?
