recreation guide

Mrs. Wilmot in Riding Dress (1763) by Joseph Wright of Derby is a portrait that exemplifies the artist’s transition into the Rococo style while maintaining his characteristic attention to light and texture. Wright, known as 'the first professional painter to express the spirit of the Industrial Revolution,' specialized in portraiture and landscape art, often employing tenebrism—an exaggerated form of chiaroscuro—to emphasize the contrast between light and dark (Source 5). While this specific work is a portrait, Wright’s broader practice involved a meticulous approach to oil painting, likely utilizing the methods described by contemporaries such as Sir Joshua Reynolds, who noted the use of oil of copavia as a medium and a limited initial palette of black, ultramarine, and white for the first and second paintings (Source 1). The artwork serves as a record of the sitter’s social status, consistent with the 18th-century tradition where portraits memorialized the rich and powerful or the rising middle class (Source 6).

preparation

surface prep

The canvas should be prepared with a ground suitable for oil painting. While specific preparation for this canvas is not detailed in the sources, the method described by Reynolds involves painting directly onto a prepared surface using oil of copavia as a medium for the initial layers (Source 1). The surface must be dry and stable to support the subsequent glazing and scumbling techniques.

underdrawing

For complex compositions or portraits, the artist may first create a complete pencil, ink, charcoal, or oil sketch to establish the general form and rough likeness, especially if the sitter's time is limited (Source 2). In Wright’s practice, the face is likely completed first, with the rest of the figure and clothing following (Source 2). The underdrawing should be light enough to be covered by the subsequent monochrome underpainting.

underpainting

The underpainting is likely executed as a grisaille (monochrome) using black, ultramarine, and white, mixed with oil of copavia (Source 1). This stage involves mentally extracting red and yellow colors to establish the tonal values of the composition (Source 1). This method allows the artist to focus on light and shadow without the distraction of color, a technique consistent with the old masters’ practices (Source 1).

composition

The composition likely focuses on the sitter’s face and hands, which were often painted by the master, while the clothing and background might have been completed by apprentices or specialists (Source 2). The background may be simple or devoid of content to emphasize the sitter, or it may include symbolic elements representing the sitter’s social status (Source 2). Wright’s use of tenebrism suggests a strong contrast between the illuminated subject and the darker surroundings (Source 5).

step by step

underdrawing→underpainting→first pass→refining→finishing→varnishing

underdrawing

step 01
Sketch the general form and rough likeness of the sitter on the canvas using pencil, charcoal, or thin oil. Focus on the face first, as is common in portrait studios.
Tip — Ensure the proportions are correct before proceeding, as corrections are difficult later.
Initial sketching

underpainting

step 02
Apply a monochrome underpainting (grisaille) using black, ultramarine, and white mixed with oil of copavia. Establish the tonal values, mentally excluding red and yellow colors.
Tip — Work wet-into-wet to blend tones smoothly. Ensure the underpainting is completely dry before proceeding.
Grisaille

first pass

step 03
Begin glazing and scumbling with oil. Apply transparent coats of red and yellow tones to the dried grisaille, similar to tinting an engraving with watercolors.
Tip — Glazing involves transparent layers that allow the underlying painting to show through. Scumbling involves semi-opaque layers that modify the underlying tones.
Glazing

refining

step 04
Continue to build up color and detail. Use varnish mixed with oil for subsequent glazing layers to gain mastery over the transparent effects. Pay attention to the contrast of light and dark, characteristic of Wright’s tenebrism.
Tip — Be aware of simultaneous contrast; adjacent colors will influence each other’s appearance. Adjust tones to maintain harmony.
Scumbling and Glazing

finishing

step 05
Complete the details of the face and hands, ensuring a lifelike likeness. The clothing and background can be finalized, possibly with the help of assistants if following historical studio practices.
Tip — Avoid overworking the paint. The goal is to express the sitter’s character and status, not just to deceive the eye with illusion.
Detailing

varnishing

step 06
Apply a final varnish to protect the painting and enhance the depth of the glazes.
Tip — Ensure the painting is completely dry before varnishing to prevent cracking or yellowing.
Varnishing

critical techniques

Glazing and Scumbling

Used to add color and depth to the monochrome underpainting. Glazing involves transparent layers, while scumbling involves semi-opaque layers. This method was common among old masters and allows for rich, luminous colors.

Tenebrism

Wright’s characteristic use of strong contrasts between light and dark to create drama and focus attention on the sitter. This technique emphasizes the three-dimensionality of the figure.

Simultaneous Contrast

Awareness of how adjacent colors influence each other. The artist must adjust tones to maintain harmony and avoid unintended color shifts.

common pitfalls

→Overworking the paint, leading to a muddy appearance. The artist should respect the vitality of the medium and avoid mere deception (Source 7).
→Ignoring the drying time of the underpainting, which can cause cracking or mixing of layers. The grisaille must be completely dry before glazing (Source 1).
→Failing to account for simultaneous contrast, resulting in colors that appear inaccurate or disharmonious (Source 4).
→Adding black to darken colors, which can cause hue shifts. It is better to use complementary colors to neutralize and darken without shifting the hue (Source 8).
