The standard pattern for early film studios was provided by the studio which Georges Méliès had built in 1897. This had a glass roof and three glass walls constructed after the model of large studios for still photography, and it was fitted with thin cotton cloths that could be stretched below the roof to diffuse the direct ray of the sun on sunny days. The soft overall light without real shadows that this arrangement produced, and which also exists naturally on lightly overcast days, was to become the basis for film lighting in film studios for the next decade.
