|"Leonard," casein 2016|
|"Erin," milk paint on panel|
Sinopia milk paint comes in a considerably more liquid form than Shiva casein, although it dries equally fast. The thinner consistency took some getting used to when mixing, but the result was a satisfying range of grays. These colors are Sinopia's Charcoal Black and Milk White only.
This is 5x8, painted spontaneously over an old oil sketch I had laying around the studio. I used the same photo reference employed for the formal portrait because knowing the subject's face meant I could concentrate more on the paint itself. There is no blue in the darks in this limited-value sketch. The old failure underneath was in mostly warm tones (the blue on the side of her face is under painting). The idea here was to paint a limited range of values as well.
|"Erin," casein on cold-press watercolor paper|
The casein delivered a full range of values and allowed good modelling of the volumes of the head, and the paint holds its chroma after drying. I have a hunch that it will look better when varnished. While I'm not sure that casein is ready for widespread use in portraits, it's certain to be useful in my practice in a number of ways. It's a fine medium for quick studies since it dries so quickly. And it may be useful as preliminary under painting for oils too. More investigations coming.
