There he devoted his life to workshops of fine art photography.

He is best known for his experimentation with chemicals, and is credited with the creation of Mordançage (tr.

'etching', ' scouring'), though he built the process on the film reversal technique first documented in 1897 by Paul Liesegang and known as etch-bleach, bleach-etch, gelatin relief, or reverse relief.
