World's Columbian Exposition

surface prep

The canvas should be primed to accept oil paint. While specific priming details for this exact work are not in the sources, traditional oil painting practice involves preparing a stable ground to prevent cracking (Source 1). Robinson’s practice involved working on prepared surfaces that allowed for the 'loosely brushed' application characteristic of his Impressionist period (Source 5).

underdrawing

Traditional oil painting techniques often begin with sketching the subject onto the canvas with charcoal or thinned paint (Source 1). Given Robinson’s shift to a more traditional impressionistic manner influenced by Monet, he likely employed a loose underdrawing to establish the composition of the exposition buildings and landscape elements without rigid outlining, consistent with the Impressionist rejection of hard contours (Source 5).

underpainting

Robinson studied methods involving a monochrome underpainting (grisaille), where the artist mentally extracts red and yellow colors to establish values before glazing (Source 6). This technique allows the underlying painting to 'make itself felt' through semi-opaque scumbling or transparent glazing, contributing to the depth and luminosity characteristic of his later works (Source 6).

Fat over lean

A basic rule of oil paint application where each additional layer contains more oil than the layer below to prevent cracking and peeling (Source 1).

Glazing

Applying a transparent coat of color over a dry underpainting to modulate translucency and sheen (Source 6).

Scumbling

Semi-opaque painting through which the underlying painting makes itself felt, often used to create a 'grey bloom' or coldness over darker grounds (Source 6).

Monochrome Underpainting

Establishing values with a limited palette (e.g., black, ultramarine, white) before adding color, a method studied by Robinson (Source 6).
