<P> A technique used in Intaglio etchings . Like etching , aquatint technique involves the application of acid to make marks in a metal plate . Where the etching technique uses a needle to make lines that retain ink , aquatint relies on powdered rosin which is acid resistant in the ground to create a tonal effect . The rosin is applied in a light dusting by a fan booth , the rosin is then cooked until set on the plate . At this time the rosin can be burnished or scratched out to affect its tonal qualities . The tonal variation is controlled by the level of acid exposure over large areas , and thus the image is shaped by large sections at a time . </P>
