"The ascent of the Aiguilles Ravanel and Mummery", climbed by young guides in cycling pants: The brothers Armand Charlet and Georges Charlet, Arthur Ravanel, Henri Couttet and Charles Balmat. The film was shot by Georges Tairraz II, Chamoniard mountain photographer, representative of the third generation of a family line of mountain photographers and filmmakers. George Tairraz II's film will lay the groundwork for a French vision of mountain film; In the 1930s, a French school of mountain cinema emerged, less expressionist, more stripped down and realistic than the German school. These are the films of Marcel Ichac, Roger Frison-Roche, Samivel, Georges Tairraz II, etc. It develops according to the principles set by Marcel Ichac, in opposition to the German school. It is both about getting out of the dramatic vision of the mountain and placing the mountain and the climbers at the heart of the plot.
