Does anyone actually have a display that provides more than 8 bits
per channel? You might have 16 bits per channel in your image, but
I am reasonably sure that standard video hardware provides only 8
bits per channel. Perhaps there are monitors and graphics cards
with greater depth for high-end applications?
