Istvan Sandorfi painting from photos

This French artist demonstrates how he paints a collage-like picture from photo references. He combines vintage images with new photos of his own model for an slightly surreal effect. All work is done from photos.

Picasso work in progress

Here's a Picasso in progress filmed in 1955 by French director, Henri-Georges Clouzot, who also filmed Picasso creating 20 artworks. The film is now available in DVD format, which (as luck would have it) is also available through NetFlix. So I get to see it free! Yes, it's already at the top of my queue.
