Stow specialised in line engraving on copper. This technique required a steady hand and a methodical approach to translate paintings into black-and-white prints. His works, such as the Death of Beckett and the Death of Sir Philip Sidney, demonstrate a clear focus on narrative clarity. He often worked from designs by contemporary painters like Richard Westall. His ability to maintain the weight of a line across a large copper plate ensured that the final prints remained sharp even after many pressings.

Modern collectors value the graphic quality of these historical scenes. The monochrome palette of a James Stow print fits well in minimalist or traditional rooms. Works like his portrait of Thomas Sprat or Marie de Rohan document specific figures from British and French history. These prints record the Regency era's interest in national history and classical composition. They offer a clean, architectural look that complements modern interior design.
