[Leica] Analog v. Digital

[bdcolen at earthlink.net (B. D. Colen)]

Ah, here we go, wandering off down the Yellow LUGroad. 

Digital smidgital - I would submit that what we're really talking about
is electronic image capture v. film image capture: using the first
process the image - light - passes through the lens, strikes an
electronic sensor, and is converted to electrical impulses and stored
electronically; using the second, the image, light, passes through the
lens and strikes and exposes a piece of film, creating what will become
a negative of the image - or a positive in the case of a slide, and is
"stored" on the film itself.

And "digital" printing is, of course, either inkjet printing, dye
sublimation, or some other specific form of printing that converts the
electronic impulses captured by the camera to colors on paper.

But someone, at some point, decided that "electronic" was pass? and
oh-so-50s, and that "digital" was a more marketable term, and, besides,
it was one people could come to understand in terms of watches and
clocks - digital is modern and up-to-date, analogue is old-fashioned and
stodgy.

JustMHO.... :-)

And of course conversely film images are made up of grain clumps so are 
in that sense digital. I remember digital being explained by this 
analogy by some teachers, with the point being that if there are 
sufficient small units the picture becomes indistinguishable from 
continuous tones so in any digital system there can be an adequate 
sample rate at which the digital becomes indistinguishable from 
continuous. This does not, of course solve the thorny question over 
where this sampling rate lies!
