Blending with black does not change the image. Blending any color with white gives white. This lightens the bottom layer depending on the value of the top layer: the brighter the top layer, the more its color affects the bottom layer.

This is also the formula used by Cairo, and in earlier PDF documentation. The result is most typically merged into the bottom layer using "simple" (b over a) alpha compositing (making the actual formula f ( a, b ) = a l p h a ( b, a ) Where a is the value of a color channel in the underlying layer, and b is that of the corresponding channel of the upper layer. In the formulas shown on this page, values go from 0.0 (black) to 1.0 (white). The top "layer" also is called the "blend layer" and the "active layer". The top "layer" is not necessarily a layer in the application it may be applied with a painting or editing tool. Most graphics editing programs, such as Adobe Photoshop and GIMP, allow users to modify the basic blend modes, for example by applying different levels of opacity to the top "layer". The default blend mode in most applications is simply to obscure the lower layer by covering it with whatever is present in the top layer (see alpha compositing) because each pixel has numerical values, there also are many other ways to blend two layers.

Unzip downloaded file into $HOME/.local/share/krita/ (merge if prompted) I would recommend watching the short video below before you download, it will show how the brushes are used and what they look like. – I believe there’a a bug in the way bundles are packed in Krita (which I’m about to report), so the safe – albeit a bit less straightforward – way for me to share these brushes is still “the old way”. – for the cloud brushes in particular I had started doing some research in metheorology so that I could name each brush the proper way (cirrocumulus, altostratus, etc). When the brushes exceed this number, I’ll split them into multiple sets (like Clouds I, Clouds II, etc). – I like my popup palette in Krita to have 12 brush icons (it’s just a matter of preference), so my sets will always be made of 12 brushes. It does take some time for me to put everything together in a way that’s usable for other people, so I’ll release all sets one by one when I can.Īt the end I’ll probably create a “Downloads” section on this website so that they’ll all be easily available in the same place. I’ve been trying to post some of my Krita brush sets for quite some time now.ĭue to lack of time or other reasons I never got the chance to do it until now, so there you go.
