Thanks!

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.

Yes, painting with filters is cool -- but it's not what you want. You can use this \
tool to add extra redness, for instance, or paint sharpness onto the image.

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.

&gt; Unfortunately, I fail to find out how to use the dodge or burn \

scans. In CinePaint or &gt; GIMP, you can simply select the \
burn/dodge tool from the tool palette, &gt; choose which you want to \

(highlights/midtones/shadows). Then, just use the mouse and it &gt; \
