Heliogravure is an intaglio printmaking process using photography to transfer an image onto a copper plate. It's like a super fancy, old-school photo printer. πΈ The plate is then etched and used to create prints with rich tones and fine details. It's a method for creating high-quality reproductions of photographs or artwork. πΌοΈ Think of it as the Instagram filter of the late 19th century. It combines art and science to produce beautiful prints.
