and no only used DSLR's and i havent the faintest  |
It is quite simple. Well depth is the maximum signal that can be recorded without saturating. You will find it is far higher than most DSLR's apart from most top end Canons.
Well depth is proportional to pixel size. The larger the pixel the greater the well depth. Signal to noise can be considered as a ratio of maximum well depth to all the other factors that contribute to noise inherent in the detector or sensor pixels.
