This introduction to light for students and visual artists explores the way light can be used to create realistic and fantastical effects in a wide range of media. Divided into three parts, the clearly written text explains: the fundamental properties of natural and artificial light; how to create realistic images by observing people and the environment; the creative use of light in composition and design. Updated with revised photos and artwork, as well as 15 practical exercises and new online video material, this second edition is an indispensable resource for animators, digital illustrators, painters, photographers and artists working in any medium.
