As Joseph Zbukvic explains, in order to set the mood in a composition, artists need to set their clocks - their watercolour clocks, that is. The watercolour clock is a simple, but ingenious teaching device Zbukvic created to show artists how to manipulate watercolor materials for dazzling, atmospheric effects. The clock accompanies every visual example in this book, helping artists anticipate how the condition of the paper (wet, dry, moderate, etc.) will react to various watercolor mixes. Based on this teaching principle, Zbukvic guides artists through step-by-step demonstrations that clearly illustrate how to: Identify a subject; Plan a painting; Control colour and value; Manipulate edges; Add the right finishing touches.: With this book, artists can achieve a greater level of mastery with watercolour and deeper, richer paintings.
