Sil,
Appeciate the time and effort gone into your reply....
My "back-up" when considering Well depth, and Image bit size has been the Hamamatsu article.
http://hamamatsu.magnet.fsu.edu/arti...amicrange.html
The image bit size, as you say is selected by the post-processing software not the camera.
This discussion came from some discussions where separate 8 bit (camera) images were stacked (summed) - the claim was made that the large ADU count in the sum required greater image bit size usage.
I then said I use 10 bit SER Video frames and stack hundreds of them (solar imaging)- does this mean I get the equivalent of a 98bit image??????
(I know when they are stacked (median combine) the result is still a 10 bit file)
The answer given,.....yes ofcourse!!
He would not be convinces otherwise.......
