And there is the crux. We determine to test either, a) the material,
or b) the material given certain parameters, i.e. "in real life."
But, since "in reality" there is no "real life", other than multiple
options from which we choose *one*, "what do we test?
Testing film in the camera seem intuitively correct, and it works
reasonably well in practice, but for comparing EFS and CI with
different films this method is for all practical purposes useless.
