Gatton is a pioneer of photo-sculpture as a fine-art medium, having worked in the field since the 1980s. Photo-sculpture combines the two-dimensional veracity of photography with the three-dimensional reality of sculpture. This enhances the presence and essence of the subject. Photo-sculpture is, in some respects, a postmodern translation of the remarkable polychrome sculptures of Greek antiquity and the Spanish Golden Age, when artists sought to envivify their subjects with exquisitely detailed surface treatment.
