Here's an oil plein-air sketch from two weeks ago. Several friends and I had a rendezvous at the former home of Chauncey Ryder, in Wilton, New Hampshire. My first post, on 29 February this year, was a birthday salute to Chauncey, a long-time favorite artist.
I posted the grisaille for this 8x12" canvas on Facebook at the time, but I've only now got around to working on the canvas in color.
Here's a detail, followed by the whole oil sketch. I've put in the detail as a reminder of the effects that you can get with sgraffito.
In this case, the canvas had been toned with transparent red oxide (Old Holland). This yields an orange surface, often ideal for landscapes in sunlight.
This time, however, I was interested in the reflected light, from the sunny lawn, that was bouncing up onto the shadowed front of the house. Each of the bottom edges of the clapboards received the thinnest sliver of warm light.
The same technique can be valuable in shadow masses and among grasses in pastures and meadows.
