That's a Bullshit reply Jim ;o)

If you'd read the whole post you would have noted I referred to hi-bit
(common parlance for more than 8-bit) image files.
Digital cameras CANNOT process the flash information as it arrives (on
the fly)  to jiggle whatever: how would that work for tailflash?


What they can do *FOR OUTPUT* is convert the "raw" internal files into
WB-adjusted 8-bit per channel files.  There, you have your jpegs ...

Now if the user always downloads the raw anyway, what is the problem?
Can't the software equally well post-process the 10-, 12- 16- or
whatever they are bit per channel files to yield the shot with a
different colour balance?



I'm interested though: how do digital cameras "do" WB?   When are the
decisions actually made?  When are they implemented by the system?  Is
any processing done before the data gets moved from the CCD to the
"raw-file" or is it all as the monochrome R,G,B and G channels are
translated into RGB.
