Somebody asked if I had links to the company that makes a business of post 
processing ccd/cmos
sensor data to minimise noise etc before a/d conversion.

Here is a link with some comparisons for their chips against various comercial 
camera
implementations. Interesting, they now have a whole lot of firmware aimed at 
guessing faces etc
and optimising results. Also interesting to see effects of WB settings and how 
bad an effect this
can have. The gamma correction is particularly interesting in optimizing 
dynamic range over
22bits.
