Argyrotype takes the photographer back to first principals - using a silver based sensitizing solution which is coated onto a quality art paper. Argyrotype is a user-friendly iron-based silver printing process that produces brown images on paper. It is derived from the Argentotype, Kallitype, and Vandyke processes of the 19th Century, but has greater simplicity, improved image stability and longer sensitizer shelf-life.
The Fotospeed Argyrotype Sensitizer uses a silver-based sensitizing solution, coated onto a quality art paper. Exposure is by natural sunlight (you may need a UV light source for the winter months or for speedier exposure) and development is in water with fixation using a simple hypo solution. Argyrotype prints are warm toned giving good contrast and midtone definition. Being silver based they can then be toned and dyed as they would have been in the early days. You make all images are made by the contact system, where the image depends on a negative of the right size.
