Raising Standards In Natural History Dioramas: The Background Painting of James Perry Wilson

Abstract James Perry Wilson transformed the subjective methodology of diorama background painting into a more objective practice by replacing an emotional and interpretive model with one based on the science of optics and other supportable references. He also succeeded in creating an overall mood in each of his diorama paintings. This article documents the step by step process of Wilson's methods. Wilson's two methods for documenting the site chosen for the diorama were: a plein air field painting, and panoramic photographs. At the museum, he created a complete scale model of the diorama and its background, accurate in all aspects, though miniature. On the full‐scale diorama background, a charcoal underdrawing preceded the painting. The sky was painted first, next the horizon, then the mid‐range distances, and finally the foreground. Each stage increased in colorvalue contrast and in resolution of detail. Wilson's mastery is most evident in the “tie‐up,” where the painted background meets the three‐dimensional foreground.
