Re: Dynamic range and RAW file "bit depth"

this is an interesting though. The sensors do not record linearly. There is more data represented in highlights than in the shadows. That's why cameras with higher bit-depth resolve better in the deep shadows.

Not every charge value has to be represented by a bit. Digitization always takes a range of analogue values and lumps them together. Digitization is a measure of 'accuracy' of representation of electron charges, much like number of pixels on a screen are a measure of accuracy of representation of a real object.
