Color/B&W Measurement Learning Material

Color/B&W Measurement Learning Material

2006-12-24 by Bob Marsolais

Mentions to the Lab measurement system and other measurement methods
are often made on this forum, and I'm sure I'm not the only one who
does not understand much of what this means.  Is there a book, white
paper, or other reference that you experts would recommend to we
learners that would help us understand these concepts better?

Thanks!

Bob,

 

With respect to the colors and where they are on the Lab scheme of things,
see my cheat sheet at http://home1.gte.net/res09aij/RGB+Lab.jpg

 

The Lab Lightness scale is the amount reflected: pure white = 100%, pure
black = 0%.

 

Google "Lab CIE" and you'll get all sorts of info.

If you really want to get into Lab Color, get a copy of Dan Margulis's 
wonderful "Photoshop LAB color - The Canyon conundrum and other 
Adventures in the Most Powerful Colorspace".
But be prepared to spend many hours reading and re-reading it!
If you only print monochrome, forget the above!!
Happy Season/Time of the Year/whatever to all group members.

Geoff
