This detail is about the size of a credit card. I knew when I started that the horses would be moving around. None of them were going to pose for me. Groups of them came and went from the corrals as the cowboys did their daily rounds.
Given those dynamics, and given the many layers of detail in the middle ground, I constructed the entire scene with the brush, without a detailed preliminary drawing. I worked from background to foreground, overlapping detail. Below is how the painting looked partway along.
At this stage there are no horses or fences yet.
Because of its opacity and quick drying qualities, casein is very well suited to this sort of approach, but it wouldn't work so well in watercolor or oil. Watercolor demands more careful preliminary drawing, and oil can get messy if you try overlapping too many wet areas.
I fully documented the process for my upcoming video "Casein in the Wild," which I'll start editing in a month or two. So please ask me any questions you might have about this way of painting, and I'll be sure to address them when I record the voiceover.
I'm at the SKB Foundation Workshop in Dubois, Wyoming.
