Section D.4. Color Tool Improvements

D.4. Color Tool Improvements

Aside from GEGL on the back end, there are a few user-visible changes in the color tools. Ever wondered how Brightness-Contrast, Levels, and Curves (Chapter 2) relate to one another? The Brightness-Contrast tool now sports a button that lets you Edit these Settings as Levels. Click the button and you're taken to the Levels dialog, preloaded with settings equivalent to what you had set in Brightness-Contrast. Even better, the Levels dialog gives you the chance to Edit these Settings as Curves. You can't go back the other way, though: Levels is more complicated than Brightness-Contrast, so you can't take a Levels setting and show it in terms of just brightness and contrast, and likewise, Curves is more complicated than Levels.
