- Physautotype
The physautotype (in French, "physautotypie") was a photographic process, invented by Joseph Nicéphore Niépce and
Louis Daguerre in 1832, in which images were produced with the use of lavender dissolved in alcohol as a photographic agent. This solution, once applied to a silver plate, was then exposed in acamera obscura for several hours to create a photographic image.References
