How to use granulation?
You've probably heard this term more than once. Some well-known artists really love granulating paints. This feature makes these pigment quite popular.
But not everyone knows how to use this feature correctly.
Paints consist of pigment and binding material. Pigments can be of different nature. For example, the company "Daniel Smith" produces paints based on ground stones. As you understand, the texture of different pigments also varies accordingly. Pigments of a "coarse" grind easily separate when mixed with water and settle out. And since watercolor paper is often textured, the pigment unevenly accumulates in the cells. Thus, when the paint dries, we get "noise" on the paper.
But why do we need paints that break down into colorful dust? And why add more complexity to the choice when there are so many beautiful paints available?
Let's think about how to turn the disadvantage of such pigments into their strong side.
After all, if we compare, for example, a clear blue sky and a clear blue wall, these two objects, despite their similar color, have different characteristics. A rough, not quite even wall, with imperfections from construction, battered by rain and wind, painted first with plaster and then with paint, will differ in texture from a smooth, homogeneous sky, right?
And now think about how to convey the texture of a rusty castle? Or sand?
Here's where we consider using granulating paints.
They will help us convey the texture of the surface without applying any special efforts.
We'll continue painting the sky with familiar pigments, and the rough surfaces with granulating ones.
Summary
Pay attention to the granularity of paints and use it accordimg to your goals.
