Meet the GIMP #55: hic sunt dracones - Adventures in LABland
This week I take a trip into the future of GiMP - by visiting Cinepaint. I read in the book “Welcome to Oz” from Vincent Versace (Tip for the German audience: Wenn ihr das Buch bei einem an den Großhandel LIBRI angeschlossenen Buchhändler bestellt, ist es billiger als bei Amazon!) how to adjust colours in LAB mode. He claims that it is much more intuitive than in RGB - and he is right.
I was so fascinated by playing with these colours that I spent a long time with that. If you get bored - just switch off. The only information after the start of John Pazdan’s “Lazy Ass” music is, that I save the curve for later use with the big image.
Result of this expedition into color space: There are no dragons out there, but now I want 16 bit and I want LAB! Now!
At the very start of the video I take up the “opacity painting” and forward you a tip from Daniel, how to select an area of uniform opacity.
I said once: “No ads here!”, but here is one:

BTW, “hic sunt dracones” means “Here are dragons” and was used by a map maker in medieval times to mark unknown territory.
