Hi Everybody,
I have a new crusade.
"Color depth" is a poor choice of words for 8 bits/channel vs. 16 bits/channel.There is no "depth". What's "deeper" about bits/channel.The range of colors is identical in any color space for either choice.
The difference is the total number of gradations of color -- 16 million vs trillions.
I don't have a good name for it. Perhaps "color resolution" ? ?

Phil1923 said:However, the "depth" of an 8 bit RGB color space is usually taken as 16.77-- million variations in color.
First, you mean color model, not color space.
8-bit color: there are 3 bits (8 possible levels) for each of the R and G components, and the two remaining bits in the byte pixel to the B component (four levels), enabling 256 (8 × 8 × 4) different colors.

I still fix my own car, I prefer to be self-reliant in all kinds of ways. :-)
Hi Jeff,
I'm not certain that I understand your post.
1. The only places that I have seen a distinction between color model and color space is in your post and Dr. Petrov's tutorial
2. 8 bits is common-place language for 8 bits per channel. ditto 16 bit.
Here are some quotes from "Blend Modes" by S. Valentine (2013). I used the same language.Phil

Phil, Since Ariel and I agree already, there's nothing to explain. Cheers everyone![:)]
Jeff for a guy like me the only real issue is the future, I archive RAW and 48bit TIFF as the output technology is always moving forward I look forward to producing copies of prints that were shot 5 years ago or older better than ever before!
