His technique focused on the clarity of the line. In works like Archivolt in the Duomo of Murano or Aiguille du Dru, Armytage demonstrated a mastery of architectural detail and natural forms. He did not rely on heavy shading to create drama. Instead, he used fine, disciplined strokes to define texture and light. This approach was suited to the Victorian demand for topographical accuracy and historical subjects, including his interpretations of Turner’s watercolours.

Modern collectors value Armytage for the technical precision of his engravings. His prints offer a window into nineteenth-century tastes, ranging from romanticised historical scenes to strict architectural studies. Because he worked closely with figures like Ruskin and Turner, his prints possess a scholarly quality. They suit contemporary interiors that favour clean lines and historical documentation over abstract expression.
