My process of making abstract aquatints is usually highly improvisational, yet the two representational Color Aquatints prints you see here were meticulously planned.
"Rose Westerland" (top left) was based on a color photograph using three plates, one for each of the three colors red, yellow, and blue.
In "Big Sur" (top middle), which is an imaginary scene, the method involves etching in several stages to differentiate the tones from bright white to black. Bright areas of this print were varnished to prevent etching, and shapes were successively masked from lighter to darker. On the beach, acid was painted onto the surface to create watercolor-like tones (called "spit bite") before it was masked.
