Large visual elaborations of Kirchhofer means most simple devices and childish in cinema archeology, Thaumatrope the Praxinoscope, all optical toys. This fundamental investigation of the batch becomes particularly clear in Sensitométrie III (Sensitometry III), where work on the range is very pure because it is accentuated by the open opposition between positive and negative. But the difference is that, where other devices seeking forms of regularity and stability to swallow motionless in the mobile, film Kirchhofer rather explore all possible rhythms, so to enhance the irregularity, difference, discontinuous. The parade always comes up against the still image, continuity serves monumentalize Meanwhile, the optical illusion is stripped and the beauties of the irregular explode.
