Recent siderotypes

Siderotype is a general term coined by Sir Francis Hershel in the mid-19th century to designate a photographic print made with an iron-based process. Amongst the multitude of processes invented in the 19th century are the platinum/palladium print, and the cyanotype.

The following prints were made using the Malde-Ware Platinum-palladium process, as well as Mike Ware’s New Cyanotype, which are both contemporary variants and improved formula developed by Dr. Mike Ware and Pradip Malde in the recent years.

I don’t think anyone has written more extensively on the subject than Dr. Mike Ware, and much reading is accessible on his website at
