Grayscale and Millions of Grays. Take a nice piece of water color paper and tape off a one inch by twelve inch window. With a well chosen brush, use India Ink and Water and make a perfect Grayscale! Starting with solid black varying to solid White, at the end, with a Fifty Percent Value dead center. Practice this until you get three in a row. If you get it the first time, then the Smithsonian is waiting for you to be bronzed. Because you are a God!
