In the sidebar to the right, I have posted a link to Artlife, an Australian site, which although at times quite wordy, has excellent material on it. An example is this short film below made by Man Ray, in 1923, although the music has been added later.

The speckles in the first few frames are salt and pepper. One of the shapes that appears is an egg crate. The model is the famous Kiki de Montparnasse, muse to many.

Man Ray (Man is short for Emmanuel) was an artist who was an important part of my photographic education.
