Some scanners use 36 bit (12,12,12) or even 48 bit color (16,16,16). For
these devices image quality is much more important than speed, and
supersampling color allows better downsampling.

The good ol. Parhelia... Always wondered under what circumstances 30-bit
color can be useful. Common image formats like BMP, PNG, JPEG, etc. only
store 24-bits. Does TIFF or RAW allow 30-bit?

There's also video cards that can do 10+10+10 bits instead of 8+8+8, in
which case a CRT is currently the only choice.
