Much of the emotion in a painting is achieved from the sensitive use of light in the subject. Without its effects paintings often look flat and bland yet it is something that many artists find quite daunting. Following on from his book How to Mix and Use Colour, Tony Paul presents this structured course on the understanding and practice of tonal control. The book is divided into eight parts, culminating in a series of step-by-step demonstrations in seven different media. Subjects covered include colour and tone, how to use and control light, different kinds of light and tonal keys. Paintings by Tony and other artists are used to bring the information and the teaching to life, functioning as examples of the points being made.
