Is there a good tutorial for GIMP 2.8 software, that explains, comprehensively, how to use the GEGL operations (which have the the advantage of being nondestructive) for photo images?
When I look for tutorials, I find only very basic tutorials or some documentation that is targeted to developers, or deprecated stuff. I am interested in using the GEGL enabled features in GIMP for photo ediing, from the perspective of an end user. At this time, this is poorly documented.
I want to do only tasks of intermediate complexity in GIMP, e.g. retouching, clipping, layering. No color space conversions, no algorithmical, context-dependent void-filling etc
