Watercolor Techniques by Mary Helsaple

The Physics of Watercolor provides descriptions and illustrations of 'what happens when watercolor hits the paper'. Helsaple explains: "After numerous requests over the years, I finally decided it was time to illustrate the skills required to become proficient in detailed watercolors. This is not a book about 'how to create a painting.' Most people already know what they want to create, and they just want to know how to get there. This guide will help you learn to watercolor well. Just as you must learn to ride a bicycle before attempting a cross country ride, it is necessary to first learn the physics and techniques of watercolor before you create your masterpiece."
