This is when I really mess things up. Good idea to have the previous layer dry so the paint can slip over. Brushing in areas on the flesh where I want to push the tone from light to dark. After scribbling these notations, a thin middle tone is painted over the whole flesh area. Again, working lights into darks and darks into lights. And the whole process can be repeated layer after layer until the painting is finished. Not exactly a "put the stroke down and leave it technique" like alla prima... but nothing wrong with experimenting in different styles.
After teeshirt dried overnight, painted a thin glaze of middle value over the area, thinned with enough medium to see the underpainting through it. The lights and darks will be painted while this layer is wet. Blending is as easy as the alla prima technique (painting wet into wet), which it almost is. Will finish each area of the painting in this way, sometimes repeating layers until it's the way I want it to be. Found out about this technique in Philip Pearlstein's book, THE PAINTING AND TEACHING OF PHILIP PEARLSTEIN.
First stage. Transferred image with the grid method. Rough sketch in acrylic for underpainting. (Gesso is acrylic and as long as the acrylic underpainting is kept thin, oil can be painted over it.) Want to push the values, lights and darks and this sketch gives me a good idea where they will fall on the figure. Painting will be done in layers, unlike my portrait studio sketches which are alla prima (wet into wet) and finished on the spot. My attempt at a grisaille (monochrome underpainting) was difficult and not carried through because of the acrylics. Now I remember why I hate painting with acrylics. The paint dries much darker when dry. Will try this method again in oils. A good example of the grisaille method is by Jeff Hayes on his blog. Follow my link to his site on the sidebar.

Wasn't happy with this one until I changed background color. Still not very happy with it, but sometimes you just have to let it go. The scanner changed the values, flesh more like first one. Took right ear off in an attempt to make form turn. Right side of face is too big on first view.
