markuswaeger Posted December 21, 2015 Share Posted December 21, 2015 When I select Lab in the info panel the values are shown as L W B. I think L must be Lumance. But what do W and B stand for? And why the values are not named as L, a and b?

Staff MEB Posted December 21, 2015 Staff Share Posted December 21, 2015 That's a bug. Thanks for letting us know. It should read L, A, B. Quote A Guide to Learning Affinity Software | Affinity Quick Reference Link to comment Share on other sites More sharing options...
markuswaeger Posted December 21, 2015 Author Share Posted December 21, 2015 Thanks. I was afraid this means something I do not know about colour. :) Quote Markus Wäger | German Autor | Graphic Design, Photoshop and Photography Expert | preparing a german book about Affinity Photo http://www.markuswaeger.com Link to comment Share on other sites More sharing options...

AndrewRodney Posted December 21, 2015 Share Posted December 21, 2015 Speaking of Lab output values, I wonder which approach is 'correct' and make sense in terms of clipping to -128. Case in point is Green 255 in ProPhoto RGB. It is an 'illegal' imaginary color. In both Photoshop and Affinity Photo, it's shown as an aStar of -128. In Adobe's Lightroom, it's not clipped, it is shown as -187.7 (the decimal values CAN be useful, more later if you so desire). Which is correct and more useful to the end user? I personally prefer how Lightroom provides a value that doesn't clip to the +/- 128 value, it tells us this isn't a color!

AndrewRodney Posted December 21, 2015 Share Posted December 21, 2015 I think L must be Lumance. It's actually Lightness, not luminance FWIW. Luminance (Luminosity) is a measure of the total radiant energy from a body. It has nothing to do with what a human perceives.

markuswaeger Posted December 21, 2015 Author Share Posted December 21, 2015 Thank you Andrew. It ist Helligkeit in german and that means Lightness in english. I sometimes tend to mistake terms especially in foreign languages.
