When I'm painting with a group, I often like to turn and paint my friends. I was sitting next to Max Ginsburg (b. 1931), so I painted him.
I used five colors of casein: cobalt blue, Venetian red, golden ochre, raw umber, and titanium white.
I did the block-in with a half-inch flat brush, and then worked the details with a small round synthetic sable. I was setting up the whole thing for the warm reflected light that bounced up from his painting.
Most of the artists in the group last night studied under Max (whose painting is on the second step up on the right): Me, Kevin Ferrara, Jeanette Gurney, Richard Scarpa, Daisy De Puthod, Max Ginsburg, Mark Texeira, Ricky Mujica, Garin Baker, and John Varriano
Edit: Wade asked what kind of pad I was using, and it was a Moleskine watercolor notebook.
