oversimplifying: you cannot distinguish between two intensity levels if their diffrence is not greater than the noise...

Hi everybody,

I don't understand why the dynamic range of a CCD is defined as the full-well capacity divided by the camera noise, and not minus the camera noise.

Thanks a lot for your help,

Laurent.
