The Foam series began as a meditation, while running on New Brighton beach, observing the moving and changing forms of seafoam on the surface of the incoming water. 
Early photographic precedents can be found in the work of Ansel Adams, Edward Weston and his son Brett, who recognized the beauty of sea foam. Louis Hock's 1979 Southern California  was a 3-screen film installation showing aerial views of incoming waves and spreading foam.
The foam is made of silica, from plankton, composed of many small  bubbles (or cells), each reflecting the surroundings and sky, part of a larger mass.
Using enlarged snapshots and acrylic medium, images of foam first appeared in my work in the Intertidal series (1993-98), which included two 2 x 4' panels depicting the surface of the intertidal zone of a beach. In these works, the transparency of the photo and the texture of the white canvas underneath give the image a heightened realism. The white cells of the foam become more pronounced. 
Intertidal reflects the whole, a cosmology, in its shells, sand and foam.
The Foam series, started in 1999, consists of smaller works on canvas, presently numbering 43.
