This is a very helpful demo about how to use the Jewell Box Viewfinder. Artist, educator and inventor Dr. Russell Jewell shows how to find and capture an effective composition when you're outdoors, surrounded by infinite possibilities.
Dr. Jewell originally discovered the concept for this product while teaching a quadriplegic student to paint (by using his mouth to hold the brush). He realized that any painting student could benefit from this useful tool. There will be an article by him in the June 2009 Watercolor Artist Magazine.
