There's lots of literature online -- wiki is a good start.
Also this site is well-known: http://www.brucelindbloom.com

Richard mentions some of the terminology used.
The L of LAB is called Luminosity --- this is the unit linearized by QTR driver.
Then Y of XYZ is called Luminance -- corresponds to your reflectance.

Google/Wiki CIELAB, CIEXYZ for formulas.

Richard, thanks a lot! I'll take a look into this topic. Your table helps a lot.

Can you recommend literature that makes reflectance, density, LAB, tristimulus, etc. and the corresponding calculations more accessible?
