@NathanG - Yeah, that’s easy for a computer or a printer – but not so easy for a human being. Can you imagine the laborious, tedious nature of Georges Seurat's pointillism?
You have to create so many little points in order to make one large picture. In essence you have to learn to see both the forest and the trees, and you would certainly need endless amounts of patience as well.
My hat is off to anyone who has the determination to paint in this style, especially in the modern era when there are so many other choices available to create an art painting.
