OK. Let's try this again. "Grain" is loosely used in a variety of
media to describe the effect of a mismatch between the resolution
of receiving and transmitting media. TV screens have "grain" even
though they are not physical silver particles on an emulsion.
Once again, with feeling, "grain is the result of resolution."
