artists who used the camera lucida
It was after using a camera lucida in 1833 that the the pioneer of photography William Fox Talbot began his attempts to fix images chemically. David Hockney has speculated on how great artists have used the camera lucida in his book 'Secret Knowledge: Rediscovering the Lost Techniques of the Old Masters'. (for a very brief summary of some of these ideas, see his article in RA Magazine from Summer 1999).
