Work in Progress Kallitype Prints 

 

The Kallitype print is an iron-silver process. A chemical process similar to the Van Dyke brown based on the use of a combination of ferric and silver salts. While Van Dyke brown and argyrotype use ferric ammonium citrate, the light-sensitive element used for the Kallitype is ferric oxalate. The use of ferric oxalate allows for both extended shadow definition and contrast control. Many developing solutions can be used to give a different image color. Kallitype images generally have a richer tonal range than the cyanotype. When the image is toned in palladium, the result is nearly chemically identical to a true palladium print.
