"It seems like "analog” has come to mean simply NOT digital and, as Fred says, 
usage has now made this meaning correct.”

“Analog” is also a way reminding us that photochemical processes proceed in a 
“continuous” manner rather than the “discrete” steps employed in Digital.

There is also an implied virtue to a “continuous” process that we see in the 
old  Analog-Records vs CDs debate. Of course, that debate assumed a sampling 
rate of only 44.1kHz. A current debate — continuous verses sampling rates of 
96kHz or 128kHz — might well flip virtue to discrete. Digital sample size — 16 
bits verses 24 bits — might also make Digital more appealing.
