His approach focused on the tonal possibilities of the monochrome print. Masson did not merely copy other works; he interpreted them. In his etchings after Eugene Delacroix or Decamps, he used varied hatching and cross-hatching to suggest colour and depth. His line work is precise yet retains a sense of movement. This method made his prints popular for high-quality art publications and private portfolios. He often chose subjects with dramatic lighting, which suited the high contrast of the etching process.

Modern collectors value Masson for his ability to bring the atmosphere of the nineteenth-century salon into a contemporary space. His etchings offer a bridge between classical technique and the graphic clarity of printmaking. These works suit minimalist or traditional interiors because they rely on form rather than a complex colour palette. A print by Masson provides a sense of history and technical mastery. It is a study in how an artist can convey weight and emotion through black ink on paper.
