Tricolor gum bichromates

My love affair with the altered landscape began in 2003 when I moved to South Carolina for graduate school. There I saw my first kudzu. This beautiful plant with its heady fragrance, purported to grow up to a foot a day, transforms everything it covers into sculptural wonders. In the process it smothers its host, robbing plants, bushes, and trees of sunlight and nourishment so that they eventually die. I am fascinated by something so beautiful yet so deadly, a botanical femme fatale. All my work is in some form of alternative process, has been for almost 20 years. This series is in tricolor gum bichromate, platinum, and cyanotype over platinum.

Summer Rain
I revel in the beauty of the physical world, in magical moments like this where rain droplets meld with a summer sunset. I try to capture that feeling through the gum bichromate process, which to me is the most artistically expressive alternative process there is because of its use of layers, textures, color, and the visible artist’s hand.
