Process Notes :
I continue to make silver prints using purchased paper and chemistry but have become enamored with methods from the early days of photography. Then everything was “made from scratch”.
The palladium and platinum palladiums are contact prints. The print size is the same as the negative size. A solution of these noble salts is prepared then spread on cotton rag paper. When dry the coating is sensitive to light. A negative is then placed in contact with the sensitized paper where it is held in place with a glass sheet. This sandwich is exposed to ultraviolet light for 2 to 30 minutes creating a positive image that is rinsed and cleared.
Cyanotypes are also contact prints. A solution of iron salts is prepared then spread on cotton or rice paper. The negative is placed on top of the sensitized coating and exposed to ultraviolet light for 1 to 15 minutes. The developed print is then bleached with sodium carbonate and toned with tannic acid.

For these processes all of my photographs are from in camera negatives. I shoot several post WWII medium format cameras, a hundred year old swing lens Kodak Panoram, and large format view cameras. Occasionally I am successful with pinhole and slit cameras which create an image without a lens. Both these camera types are homemade.
A digital camera does occasionally have a place in my daypack. I make use of creative filters and long exposures to capture moving sand and water. Unsuccessful attempts are easily disposed of...in the case of moving water while panning the camera, most of them. These images are printed on cotton paper using pigment inks.
