"This is J Hewit & Sons Alum Tawed Goat coated with a Cyanotype photosensitive solution, which is one of the classical photographic techniques, stacked with digital negative films, printed with an ultraviolet exposure device, and developed".

Wikipedia - 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. The process uses two chemicals: ferric ammonium citrate and potassium ferricyanide.

"Very few leather tans work with this technique, but alum tawing is ideal. Hewit's Alum Tawed Goat is very fine and the beauty and finish when tailored to leather products is exceptional.

I publish my work in a classical photographic techniques group on Facebook with 35,000 members, but I have not seen anyone else using this same technique."
