Summary:

There is renewed interest among art photographers in a number of historic printing techniques because of the remarkable effects they produce. Gumoil printing involves contact-printing a positive transparency onto gum-coated paper. Oil paint is then applied and rubbed into non-gummed areas of the print, and with bleach etching, mono-and polychromatic variations are possible.

This book presents a new method of using a 19th century contact printing technique. The author demonstrates how to use this antique medium with a new revolutionary approach. The unique results obtained from this method have led to a resurgence of interest due to the increased use of highly automated cameras and the desire to create unique, artistic prints. The reader will discover how to create beautifully tinted, mono-and polychromatic gum and oil images using the author's version of the technique. Step-by-step instructions, with detailed illustrations and directions for further experimentation provide a perfect source for learning this printing technique. The new chapter on digital printing combines the new and the historic, making this technique even more accessible for the art photographer.
