In 1990, Karl P. Koenig created gumoil printing. In 2000, I discovered his book,Gumoil Photographic Printing and taught myself the process. If you are interested in learning the process, please view Mr. Koenig in action.

Karl Koenig invented the Gumoil alternative process. He uses an enlarged interpositive to create a photographic image. The interpositive is contact printed onto paper hand-coated with a mixture of liquid gum arabic and potassium bichromate. This is exposed to an ultraviolet light source, then developed in water.

Sadly, Mr. Koenig died in 2012, but you can learn more about his life and view his stunning artwork by going to his site http://www.gumoil.com/
