The Kallitype is an alternative photo process developed in England in 1842 that involves a sensitizer mixture of iron salts and silver nitrate. The sensitizer is mixed and coated onto paper; a negative is placed on the paper under glass and exposed to ultraviolet light, then developed in a complex process.
My method, developed over the past 10 years, is rather than use a negative, to collect plants, and expose these plants under sunlight. This is a contact process, meaning the image is full size. These are also unique images, that is, there are no editions but only one image that is made by hand. What fascinates me about the Kallitype as opposed to other processes is the range of tonalities achieved through conditions such as heat, humidity, time of day, time of year, temperature, choice of paper, the variety of coating mixtures I use. I have printed in California, Wyoming, Arizona, Montana, New York State, Illinois and in 2008 and 2009 at the Neal Smith Wildlife Refuge near Prairie City, Iowa. I often think of this work as conservationist in nature.
