Degas and his friends Mary Cassatt and Camille Pissarro were all experimental printmakers who combined traditional printmaking techniques to create a black and white equivalent for the tonality and varied textures of paintings. They were all so involved in printmaking that in 1879–80 they planned to publish a journal, Le Jour et la nuit (Day and Night), that would contain original etchings. As a printmaker, Degas was ambivalent about when a plate was considered finished. What attracted him to printmaking was the variability. He thoroughly enjoyed reworking, retouching, and transforming plates, often progressing toward more subtle painterly effects.
