Other examples of what people want to achieve with these kind of modes can be seen in the following links:Ī handful of modes can achieve the full coverage property, for example overlay, color dodge, color burn, hard mix, height. Those kind of modes are useful for example when one wants to simulate paper grain or dry brush with low pressure and full coverage with high pressure (graphite, gouache and similar techniques). Perhaps the most requested mode is height, a Photoshop brush texturing mode that is like an extension of the subtract mode. This is what modes like overlay achieve: the texturing is stronger in the gray values and has no effect in the white and black values.
What most of the painters want (I think) is those modes that, while applying the texture in a similar way to the subtract mode, allow to achieve full coverage in one stroke, without having to make multiple overlaping strokes (with subtract there's always some areas that remain transparent). Now, reading those threads and from my own experience, I came to the conclussion that it is not like every texturing mode present for example in Photoshop is equally useful (or equally requested by the painters). Some threads requesting new modes or asking if some specific texture effects can be achieved in Krita appear in Krita Artists every now and then. These, although useful, don't seem to be enough for the needs of some users. MotivationĬurrently in Krita there are two modes to mask a dab with a texture: multiply and subtract.
Note 2: All the following brush images where obtained by modifying and building Krita's code and using that custom build to create them. Note 1: In the following, image pixel values are asumed to be in the range, as is the strength parameter. This doesn't propose improvements in the performance side.
This task's objective is to propose and gather ideas about expanding the range of texturing blend modes in brushes.
