Covariance

Covariance is a central work within the vast project Raphaël Dallaporta undertook about the historical relations and theoretical links between photography, science and space research. Dallaporta (b. 1980, France) has been participating in the “Creation and Spacial imagination” program organized by the French Space Observatory and the National Center for Spatial Studies (CNES). This work, which has been finalised during Dallaporta’s one-year residency at Villa Medici – French Academy in Rome (Italy), was realised in close collaboration with French mathematician Alexandre Brouste.

Covariance is a mural composition of 48 mathematical models. Each image, which resembles a fragment of cloud, has been computer-generated in the University of Maine’s laboratories (Le Mans, France) by exploiting a mathematical formula known as a probability algorithm or “covariance”. These calculations resulted in a large number of dots within a cube – each, when seen from above and depending on his position in the volume, would appear more or less dark. Moreover, the mural ensemble of 48 pieces is actually composed of twelve subgroups of 4 photographs each for which only one parameter of the mathematical formula would vary. Covariance is a work positioned halfway between the classification of an illusory object and the poetic variation on a theme.

Using an ancient and rare process (each of the 48 pieces is a cyanotyped platinum and palladium print) and choosing the title Covariance, Raphaël Dallaporta also refers to Alfred Stieglitz’s historical series which title, Equivalent (1925-1931), suggested the metaphorical role of clouds.

All the 48 images are displayed in a large wall at the gallery.
