I agree but it was as I mentioned, an artificial example. Maybe I should
have worked with what I actually have, which is a scanner with a 12 bit
A/D that the firmware drops out the 2 LSB from to return 10 bits per channel.
It doesn't matter how

I would agree with this. The intention is quite

values. For reasons analogous to the use of 16-bit

maximise tonal smoothness and provide resilience
under further editing.
