Here's something interesting......
Here is a blog post by the main guy working on HD Photo (a new file format) in Microsoft. The new HD Photo file format has been adopted by the JPEG committee and will eventually become JPEG-XR (probably sometime this year hopefully).
This blog post is absolutely brilliant in describing color spaces and aspects of color managment most do not know.
Although you may know this already, I just want to clarify it.
Color in software engineering and web-related content is described as RGB. Given that each color channel is 8 bits (or more easily referred to as 8bpc (bits per channel)), a typical C++ representation of a standard grey color would be:
COLORREF mycolor = RGB(128, 128, 128);
Orange would be:
COLORREF mycolor = RGB(255, 128, 0);
8 bits gives us a possible 0 - 255 value. My 1D camera captures images at 12bpc (because it uses the DIGIC II processor). 12bits gives a possible 4096 colors per channel. Canon's newer cameras use a 14 bit sensor which provides 16535 color variants of each channel.
Heres the link. Its a little long, but brilliant and worth spending the time to read it.
