A Couple of Small Portrait Studies (done from candid iphone photos)
Each: 10" x 8" Oil on canvas mounted on hardboard panels. Canvas mounted using Yes glue and allowed to dry 24 hours. I had never used this procedure before or painted in oil quite this small...... 
My painting procedure was: The images were sketched onto the panels with graphite. An imprimatura using Raw Umber was applied thinned with Gamsol, then I used the "rub-out" or "wipeout" technique producing a toned rough grisaille. Lights and darks of umbers, ocher and white were painted into the wet underpainting and allowed to dry overnight. Overpainting was applied using fairly thick juicy paint with broad strokes not trying for tight detail. 
Palette used for these little paintings: Burnt Umber, Raw Umber, Ultramarine Blue, Ivory Black, Cadmium Red Light, Alizarin Crimson, Cadmium Yellow Light, Yellow Ocher, Flake White. 
Medium used: Talens Van Eyck medium (an old medium containing lead, no longer available)  thinned with gamsol.
