I chatted to a friend today regarding the SNR gains that can be had and some of the issues of full well depth
It gets much more complicated than I thought !
Its very chip specific.
Apparently somebody did some measurements and concluded that the new 16mp Kodak chip actually doubles its noise when binned - so you get the gain of shorter exposure times or a deeper exposure for the same time but at the expense of noise.
Most other chips peak out at maximum binned 'revised' full well depth of around double, some dont even get to double.
I think I understand that some antiblooming chips are limited by the bleed circuitry ?
The technology and circuitry inside the CCD are what counts and not all of this info is readily available in an easy form for us to just look it up.
So more heresay than science so far from me Brendan !
If you look up SBIGs data tables on their website - some of them list the full well depth binned and unbinned - so thats a useful start since that is specific to the chip as opposed to the camera.
