TRADITIONAL OIL TECHNIQUE

PAINTING TECHNIQUE 

 

1. Prepare surface

2. Under-drawing: Draw in medium of choice, (pencil, Charcoal…), set image in ink.

3. Imprimatura: With brush or rag spread thin, transparent layer of color such as yellow ochre
or umber over under-drawing. You must keep it very thin, the drawing should show through well.

               (alternative technique: Imprimatura can be a mixed grey on the prepared 

                 surface with the drawing in liquid paint over it.)

4. Dead-color: Apply thin, pale layer of matte local color to individual forms in painting, allow to dry.
This shoud be very simple, thin paint.
5. Highlights: using a heavy, impasto, reflective white pigment such as lead white develop the highlights
over the drawing and imprimatura.

6. Working-up: development of form over dead color and highlights using glazing, scumbling and fine
careful brushwork in layers. The highlights will be raised and opaque while the darks will be thin and more transparent. 

7. Details: apply fine highlights and details over finished paint layer

8. Dry, coat with protective varnish

 

Notes: Mastic glaze medium will work well and dry quickly.
