An etching or engraving process focused on tonal variations rather than linear affects, it gives the appearance of a watercolor, and is often used in conjunction with line etching. Aquatint is created by acid biting into a metal plate and involves putting granular resin over the plate, creating the design, and then immersing the plate in acid. Tonality is achieved by repeating the varnishing and immersing. Aquatint artists include Doel Reed, Jay McVicker, William Kneass and James Kidder.
