Hill of Jallais at Pontoise

surface prep

The canvas should be prepared with a ground suitable for oil painting. While specific preparation for this exact canvas is not detailed, traditional oil painting involves sketching the subject onto the canvas with charcoal or thinned paint before applying color (Source 1). Pissarro’s practice involved painting from life, suggesting the surface would be prepared to accept direct application or underpainting techniques common in the 19th century.

underdrawing

Begin by sketching the subject onto the canvas using charcoal or thinned paint (Source 1). This initial drawing establishes the composition of the hill, trees, and sky. Pissarro’s landscapes often featured detailed natural elements, so the underdrawing should capture the essential forms of the terrain and vegetation without being overly rigid, allowing for the 'sketchy' quality noted in his work (Source 5).

underpainting

Consider using a grisaille (monochrome underpainting) method. This involves painting the composition in neutral tones, mentally extracting red and yellow colors, to establish values and forms (Source 6). Once dry, this layer can be glazed or scumbled with oil to introduce color. This technique was practiced by old masters and can help achieve the 'soft and harmonious' effect described in color theory (Source 6, Source 7). Alternatively, a lean initial layer of paint can be applied to establish the basic masses of the landscape.

Fat over lean

Each additional layer of paint should contain more oil than the layer below to allow proper drying and prevent cracking. This is a basic rule of oil paint application.

Glazing and Scumbling

Glazing applies transparent coats of color, while scumbling uses semi-opaque paint. These techniques can adjust translucency, sheen, and density, and were used by old masters to achieve harmonious effects.

Composition Balance

Avoid exact bisections and center the subject off-center. Use contrast between detailed and 'rest' areas to guide the viewer’s eye.
