The story of our Workshop / gallery/ In the heart of "la campagne a Paris"
Since 1842 - John Frederick William Herschel
Cyanotype is a photographic printing process that produces a cyan-blue print. Engineers used the process well into the 20th century as a simple and low-cost process to produce copies of drawings, referred to as blueprints.
Since 1895 - Anthony van Dyck
Van Dyke brown is a printing process named after Anthony van Dyck.
It involves coating a canvas with ferric ammonium citrate, tartaric acid, and silver nitrate, then exposing it to ultraviolet light. The canvas can be washed with water, and hypo to keep the solutions in place. The image created has a Van Dyke brown color when it’s completed.
Since 1873 - Wiliam Willis
The platinum tones range from warm black, to reddish brown, to expanded mid-tone grays that are unobtainable in silver prints.
Platinum prints are the most durable of all photographic processes. The platinum group metals are very stable against chemical reactions that might degrade the print—even more stable than gold. It is estimated that a platinum image, properly made, can last thousands of years
Since 1850 - Alphonse Poitevin
Gum bichromate is a 19th-century photographic printing process based on the light sensitivity of dichromates. It is capable of rendering painterly images from photographic negatives. Gum printing is traditionally a multi-layered printing process, but satisfactory results may be obtained from a single pass. Any color can be used for gum printing, so natural-color photographs are also possible by using this technique in layers.
