Pointillism is a form of painting using many tiny dots of primary colors to create secondary colors. This form of painting is very long and laborious and not a very common form used by many artists, however it does create beautiful optical results. Even though the sleeping dog above is not “painted” using color, it is still created using many tiny dots (points) using pen and ink. This technique is known as stippling, using dots to create a variety of less and more dense areas. This technique creates the optical feel of depth where the dots are more concentrated.
In my snow leopard piece titled,Watching I also used stippling to create depth and form.
This technique was developed in late 1880 by George Seurat, a French painter. http://www.georgesseurat.org/
