Head of a Bearded Man, Leaning Back

This album of prints, comprising 137 etchings and aquatints by Jean-Baptiste Le Prince looks just like an album of drawings. Le Prince’s aquatint technique was unrivaled in his day. To mimic wash drawing so convincingly, he used a very fine aquatint dust grain and found a unique way of applying it to the copper plate to maximize his range of tone. After etching the composition, he applied a second ground to the copper plate. Then as though applying wash, he brushed on a special solvent—made of olive oil, turpentine, and lampblack ink—to the areas he wanted tone, exposing those passages of the plate. Next he would apply a sugar solution to the bare areas. When he applied the powdered resin and heated the plate, the resin would fuse to the sugared areas, creating a porous surface.
