How do artists create different effects when painting? The medium they choose-such as oil, watercolor, or egg tempera-plays an important part. So too does the material they paint on, the pigments used, and even the type of brush. Using examples from the National Gallery Collection, Jo Kirby shows how a painting is made, and reveals the processes behind an array of fascinating techniques. With clear explanations and close-up photography, this book will help you see paintings with a fresh eye.
