Argyrotype

Argyrotype is an that produces brown images on plain paper. It is an alternative process derived from the , kallitype, and of the 19th century, but has greater simplicity, improved image stability, and longer sensitizer shelf-life.^[1] It was developed by Mike Ware.^[2]

While this process may not have the permanence of other processes such as or , it is much less expensive and more user friendly. The core resource used is (NH₂SO₃Ag) which can be prepared on site from sulphamic acid.^[2] The sensitizer used is very slow, so printing must be by contact with a large format negative, using an ultraviolet lamp or sunlight.

As with most alternative processes there is room for manipulating the process to achieve different effects, and since the image is produced on plain paper many drawing or print making processes can be combined with the original image.
