surface prep

Prepare a white or light-toned ground. Constable’s practice involved painting directly on the canvas, often starting with a monochrome underpainting or grisaille to establish tones before applying color (Source 6). The surface should be smooth enough to allow for fine broken brushwork but textured enough to hold the impasto of his vigorous sketches (Source 7).

underdrawing

Constable’s preparatory methods are not explicitly detailed in the provided sources regarding specific drawing tools for this late work. However, he emphasized forgetting previous pictures to capture nature directly (Source 7). It is likely he used a light charcoal or thinned oil sketch to block in major forms, consistent with his habit of making full-scale preliminary sketches to test composition (Source 7).

underpainting

Apply a monochrome underpainting (grisaille) using black, ultramarine, and white to establish the tonal structure of the landscape. This technique, described as extracting red and yellow colors to translate what would be left in nature, allows for subsequent glazing and scumbling (Source 6). Ensure this layer is completely dry before proceeding.

Broken Brushstrokes

Constable used small, distinct touches of paint to convey the effects of light and movement, creating an impression of sparkling light (Source 1).

Scumbling

A semi-opaque painting technique applied over lighter or darker passages to create texture and light effects, such as a grey bloom (Source 6).

Simultaneous Contrast

Using complementary colors in juxtaposition to enhance the intensity of each color, such as making red appear redder by surrounding it with green (Source 3).

Meteorological Observation

Constable annotated his sketches with weather conditions, believing the sky was the 'chief organ of sentiment' (Source 1).
