Peter Moxhay works with salt prints printed from calotype paper negatives. This is the original negative–positive photographic process, invented by Talbot in the 1840's. It is a time-intensive process: Exposures can range from 30 seconds up to 15 minutes, and development in gallic acid may take an hour or more. He believes that, in these days when billions of digital images are instantaneously produced and shared every day, it is important to slow down and return to the roots of photography.

He currently works with a calotype variant that is a hybrid of Pélegry’s dry process, which facilitates travel, and Townsend’s process, which allows somewhat faster exposures.

Peter lives on Peaks Island, in the state of Maine.
