The frame is a technique which reproduces a three-dimensional object by making acted the light on a photosensitive layer. In this photographic process the light causes the blackening of the photosensitive layer, except with L place where the object rests. It results an appearance of a white image from the object on a dark fon. First frames in XIXème century when the chemists experienced the photosensitivity of the emulsions spread out over a support. The artists ventured in this new space to see the things taking an unknown aspect until there. The members known Dada group found very interesting that this work of reproduction introduced a new technique into art. Thorough Man Ray this technique while speaking about Rayogramme: it proposed at the time the following definition: “Photography obtained by simple interposition of the object enters the sensitized paper and the source of light. Seized at the time of a visual detachment, for periods of emotional contact, these images are oxidations of residues fixed by the light and chemistry, of the living organisms. ”

Moholy Nagy developed the techniques of the frame with a great virtuosity. By modulating the light and dematerializing truly the objects. It benefitted owing to the fact that the light erases almost the objects of the image in their giving a negative form. It reverses the form of the values like Talbot. It employs the word of “painting of light” to qualify these works realized with this technique.

The list of the important artists being interested in the frame is impressive. One finds there Pablo Picasso who completed 200 operations with this technique. Rauschenberg , Raoul Hausmann ,Kurt Schwitters , Robert Heinecken, Sigmar Polke have jointly to also use the frame during their artistic career. This last seeks and opens of new way everywhere the forms generated by shelf are likely to be transposed on a table. See book the photographic one at Sigmar Polke.
