Overview:Renato Berta, director of photography who won a César in 1988, this time appears in front of the camera under the direction of Paul Lacoste, who retraces the creative process of the Swiss filmmaker. Between archive images and anecdotes about his shoots with the greatest independent directors of his time (Jean-Luc Godard, Claude Chabrol and even Louis Malle...), Renato Berta confides how, from a script, he imagines the scenes of a film.
