It, technically, isn't ANY "generation".  It is interpreted by the sensor,
then by an A/D, then by some thresholding/levels adjustment/PRNU and then a
Bayer composition algorithm...etc. etc.  The thought of "generation" with
digital camera image capture is really meaningless.  I can come up with ten
different processings that happen to the file...so if you want to assign a
"generation" to every time the data is changed, well, digital will fall FAR
behind film in that regard.  It also matters how much the "fidelity"
(accuracy of reproduction) of the image is affected by each change...

Yes, and with every processing that happens to your digital camera image it
changes the image.

Sigh.  (this isn't aimed at you, BTW)...  What makes sense is that, for some
reason, there is so much misinformation about digital imaging out on the
web, and therefore in people's minds...and that there are a LOT of people
who leave their sense behind and somehow want digital image capture to be
better than it is...for what ever reason.
