Convolutions, spirals, volutes and indecipherable ideograms fluttering on the shore stamp the random pattern of seaweed. At the heart of the visual poems imagined by Denis Brihat in a fantastical naturalistic vein, the chromatic hesitates between black-white and a diffuse colorization. A print seems to surround the head of an archaic Christ as if snorting from a shroud modeled between sooty penumbra and bronze color. Metamorphosis is at the heart of the twenty or so images by the photographer, 94, hung at the Focale Gallery in Nyon under the title A Flower of sand.
