I still think layer modes (or layer operations) have their place, especially if they involve pre-made resources (for example the Overlay layer mode I wrote about in my previous post in my case is used mainly to apply subtle textures to areas painted on lower layers, for example paper/canvas texture). > When you make invisible a layer below the one you used to brighten the > image, you would see the (faint) image structure from the hidden layer > because some of it was copied while brightening.

Now that I think about it, you're right, this could be a problem depending on the situation. > Would it be important to also be able to manipulate (eg. brighten) > the current layer only, in the way that brush modes work right now in GIMP? I think it would be important/useful to be able to affect only a limited set of layers. I think that layer groups/trees, which will be implemented in the 2.8 version of GIMP will add this capability (if a priority system based on layer position within the tree will be implemented. By the way, this is where GEGL is heading, from what I know). > I understand if you're more interested in GIMP than in MyPaint, but I am > still interested whether this would be compatible with your workflow... It appears it would be. Some issues would have to be sorted out though. By the way, this side-discussion started because on Photoshop CS4 I can use different painting modes even on totally transparent areas (if there is nothing in the background, then the brush behaves as if the painting mode is "Normal"), while GIMP does not. > And, have you already used a software that offers such a feature? I can't try it again right now, because the trial period has expired and for some reasons it doesn't work anymore (it should, but without the file save features), but if I remember well Paint Tool SAI is a very good software for illustration/painting/drawing which handles layers and layer modes better than other programs: http://www.systemax.jp/en/sai/ I think layer modes here work on a hierarchy tree structure.
