Camera lucida in use. A camera lucida is an optical device used as a drawing aid by artists and microscopists. It projects an optical superimposition of the subject being viewed onto the surface upon which the artist is drawing. The artist sees both scene and drawing surface simultaneously, as in a photographic double exposure.
Don Ihde called the hypothesis being 'hyped' and referred to clear evidence about the use of optical tools by, e.g., Albrecht Dürer and Leonardo da Vinci and others. As well the 1929 Encyclopædia Britannica [ 4 ] contains an extensive article on the camera obscura and cites Leon Battista Alberti as the first documented user of the device as ...
A camera obscura (pl. camerae obscurae or camera obscuras; from Latin camera obscūra 'dark chamber') [1] is the natural phenomenon in which the rays of light passing through a small hole into a dark space form an image where they strike a surface, resulting in an inverted (upside down) and reversed (left to right) projection of the view outside.
View from the Window at Le Gras 1826 or 1827, believed to be the earliest surviving camera photograph. [1] Original (left) and colorized reoriented enhancement (right).. The history of photography began with the discovery of two critical principles: The first is camera obscura image projection; the second is the discovery that some substances are visibly altered by exposure to light.

However, the ideas about photography in Camera Lucida are certainly prepared in essays like "The Photographic Message", "Rhetoric of the Image" (1964), and "The Third Meaning" (1971). There is a movement through these three pieces of which Camera Lucida can be seen as the culmination. With "The Third Meaning" there is the suggestion that the ...
The plate was then carried to the camera in a light-tight plate holder. Withdrawing a protective dark slide or opening a pair of doors in the holder exposed the sensitized surface within the dark camera and removing a cap from the camera lens began the exposure, creating an invisible latent image on the plate. Depending on the sensitization ...

His life as an artist was deeply connected to his scientific and technical pursuits. His optical inventions were improvements to the camera lucida and camera obscura long used by artists, [3] and allowed him to draw both landscapes and microscopic studies in lucid detail. [4] He also patented and sold his inventions. [4] [5]
