Oil Portrait Using the CSO Method by Maurice Garson

Regardless of the use of the thin transparent coats I'm working, on day two surprisingly the entire surface was dry enough to begin work.. Other than it's satin luster, it's easily as fine of a working oil medium as copal. I'm still trying to get used to thickness of the CSO.

The only problem I have incurred is a few loose brush hairs from new brushes. At this point I have only strayed from Louis' recommendation in one area. If this were a large landscape with a rough canvas I would have most likely been using a stiff hog hair brush.

Instead I have opted four four different sizes of red sable:

Click image for larger veiw
  • Bright #10 - for the back ground blending (when I don't use my fingers)
  • Bright # 6 - large detail and blending
  • Bright #1 - small area blending
  • Round # 2 - minute details

I begin with the "oil out" with my fingers for the next layer over the entire canvas. Working towards accurate definition in this rendering of the roses in her hair and the gold necklace today and I've started to work in more detail within the shadows and light using only variations of Burnt Umber, Ivory Black, Cobalt Blue & White.

Added black in the detail of the subjects hair, different tones of gray with umber and cobalt blue to shadow the flesh tones, first coat of white to the gown and of course more Cobalt blue to the back ground.

In between layers of this painting I have begun restoring an antique wood and gesso frame to use with it. I will provide a photo of it when the project is complete.

Note: I found a good palette to use with this medium to extend use and reduce waste of premixed colors.
