Camera Obscuras are another magical art tool, which have been used for centuries to enrich the way an artist sees. The Camera Obscura's image simplifies and enriches color while adding depth by focusing on one distance at a time—the same way your eyes work. Its images were seen as magical in the 17th century—often described as nature’s paintings.
The first time you see a camera obscura in action you'll get chills. It projects a clear full color moving image of what is in front of it onto the ground glass screen making it look like a tv screen that you can draw on. The light from any object comes through the lens bounces off of the mirror and up through the ground glass or paper for you to trace or just view.
