Upon reading the "Vision and Motion" article, I remembered this image and wanted to share it. In this photograph, Pablo Picasso is "painting" a Centaur with light. Light sketching is an interesting visual concept to me and one that I intend to explore in my final project.
The following is extracted from "light painting", a Wikipedia article.
The light can either be used to selectively illuminate parts of the subject or to "paint" a picture by shining it directly into the camera lens. Light painting requires a sufficiently slow shutter speed, usually a second or more. Like night photography, it has grown in popularity since the advent of digital cameras because they allow photographers to see the results of their work immediately.
Light painting can take on the characteristics of a quick pencil sketch. Pablo Picasso was photographed in 1949 doing a quick sketch in the air.
Flash lights or light pens can also be used to create Full Bleed images. Different colored lights can be used to project an image on the CCD.
