Experimentation with chemistry and photographic paper to produce various visual effects and themes describes the direction of this work. These photographs are a combination of cameraless photography and the manipulation of photographic materials by using them as painting media. The images are, literally, chemical paintings that I call chemigrams. With some of these photographs, the juxtaposition of a printed image with chemical painting creates a form of spatial interaction in which the illusion of depth is provided by the printed image. When chemical painting alone is used, black advances and chemical coloration recedes, creating another form of spatial interaction. Both of these effects tend to produce a cool/warm contrast.
