Er� still confused. I don't see how increasing the sampling rate from 8-bit
to 16-bit makes the sensor any more sensitive. When we're using terms such
as "f-stop" we're just describing a mathematical relationship. Surely just
because you can make the device more accurate in its description of what
it's recording doesn't make it able to actually record more. I think someone
else posted the example of a monitor displaying an image: whether it's
displaying 16 colours, 256 colours, or millions of colours (the bit-depth)
it's dynamic range (the difference between the blackest black and the
whitest white it can display) doesn't change.
