Ken,

The A/D like many cameras may be 16 bits but the camera itself is really only capable of producing 11.6 bits of information because of the well depth and read noise.

Log2 (WellDepth e- / ReadNoise e-)

Although that is then artificially increased by the non linear antiblooming capability of the CCD circuit in terms of reproducing the dynamic range of the original target, the camera is still only giving you 11.6 bits of useable data.

Unfortunately some camera makers like to "oversell" to their consumers by quoting the A/D circuit capability ! I am being kind here !!

True 16 bits would be 64,000 e- well depth and 1 e- read noise or 256,000 e- and 4 e- read noise !
