- Having worked on a project which samples at 48-bits (16-bit CCD
- * 3 planes) and then quantizes down to 24-bit I can say that
- the human eye CAN and does distinguish color information
- at higher than 24-bit/pixel. This information is especially
- noticeable in highlights and shading, i.e. dynamic range.
-
- When we get tired of those ugly 24-bit images we can get started
- on 36 and 48-bit images!
