Computer makes calculation doing brushstrokes, so you can easily define digital and traditional painting. The matter of those blending modes, texture abilities, color dynamics in brush tip and stroke is to dilute “digital” effect. More brushes with various tips, textures and blending modes help to step away from monotonousness of digital brush. That why I put the Greg’s landscape as the example. He is really a master of creating an illusion of traditional look in digital painting. Even now, glazing at small 400px preview I feel this illusion. I watch his process - he use textures a lot. Besides of various form of brushes with textures, he use a blending brush with mapping – sort of clone/stamp tool with ability to blend-in into existing picture. He takes huge res master painting, merge it with another picture that have colors he looks and place on top of that huge res canvas texture, and only after that use eyedropper (that take a small piece of a picture not a color) of blending brush to the canvas. Since that process is really slow-computing you need a great patience to work in such way.
About ten years ago I saw the video of making “Mona Lisa” in Microsoft Paint. So @tiar, the Greg’s landscape is definitely possible to make in Krita . I just talking that in Krita it is a harder to do.
I am not streamed into Greg’s style, but honestly I also like more painterly-nonuniform look. More blending modes give more abilities.
So the main goal is to make brushstoke (stroke without pulling off the stylus tip) as mach variety as possible. The one stroke is one shape – it is important. The stroke make an edge and form. One of the feature of multiply, substract, darken and linear burn is presence of texture and texture uniformity at top of brushstroke (I popped up it with the red in the image) . No matter how mach you draw back and forth, the texture effect will be appear and it force that digital, computer feel of brush. Open at full the image and look closer, for example, to Color Burn, - the texture of canvas is appearing near the edge, and with proper combination of brush form, opacity and flow control it makes way to closer to the traditional stroke.
Example above is a brush with Height Mode I use often . Each “painting” in the image is made with one stroke. With only one stroke I can make texture to pop up where I need and to hide where don’t. So in one stroke I can sort of control the pattern and the edges. Edges in periphery is soften and in the center is hard with the texture pronouncing. To make this in Krita I need two strokes.
And the gradient test your asking. I hope it will clarify something:
Btw, if you guys pure linux users, you could download linux version of PaintStorm and look to Height blending mode by yourselves.
So I will be glad if some blending modes beside existing multiply and substract will be added into Krita.
