Well, we simply don't really have a burn/dodge tool yet. I'm not sure where to fit it in Krita's current design: it could be a separate tool, or it could be a paintop, similar to the brush, pencil and so on. In the first case, it would be possible to burn & dodge with a soft brush or a hard pencil, or with

the airbrush. In the second case, it would be possible to burn & dodge in straight lines or across a vector path.

Well, we need still to write that section, I suppose. I'd need to dive back into the code for that, though. But it's basically just applying the chosen filter onto the area covered by the brush -- that's all. As if your brush area is a temporary selection.
