His work focuses on the everyday reality of rural life. He often painted village fairs and markets. In his piece Italianate Landscape with Herdsmen and Cattle at a Watering Place, he uses a soft, diffused light to define the forms of the livestock. He avoids the drama of history painting. Instead, he captures the quiet mechanics of the countryside. His compositions rely on a clear sense of space and a naturalistic palette of earth tones.

Modern collectors value these works for their calm atmosphere. The paintings offer a window into a pre-industrial world without heavy moralising. His scenes of cattle and travellers provide a sense of order and stillness. These prints suit interiors that favour traditional aesthetics or a rustic feel. Demarne provides a link between the precision of Dutch masters and the softness of the French school.
