    Extractions: (Tristan Tzara description of Man Ray photograms) History - Photographic adventures in the creation of photogram images in the early 1800s Joseph Nicephere Niepce , in France, in 1824 created a recorded image of a drawing by coating a sheet of pewter with Bitumen of Judea, a type of asphalt. By exposing through the drawing, and washing off the soft unexposed asphalt resulted in a photogram copy of the drawing. Niepce continued to explore ways to improve his process without significant success. He abandoned the concept of creating photogram type images for experiments in-camera and later worked with Louis Jaques Mande Deguerre on the Daguerreotype process. Hippolyte Bayard, Experiments leading to the discovery that silver salts can be made sensitive to light and the associated discoveries for the practical application to capturing images of the natural world were reported in Paris and then London in January of 1939 [Weston Naef, J.

Also Prof. Herbert Jackson also noticed in London the same effect accidentally, no one of the researchers spend much attention on it except museum here On a New kind of Rays can be found at the site of mindfully.org.
