Working en plein-air is a French term that means literally 'in the open air' and, although artists have been doing just that for centuries, the concept is experiencing a resurgence today. Sketchers and painters alike are leaving their studios and heading out into the open air. This book encourages you to join them. Full of in-depth advice and practical instruction, it explains how to make the most of painting outside and how to capture the very essence of a scene with a far greater authenticity than can be achieved when working from a second-hand image. It covers an array of mediums including pencils, pastels, pens, watercolours, oils and acrylics and advises on the best materials and accessories, from sketchbooks to easels. Also suggests suitable locations and subject matter including landscapes, seascapes and people, explaining the importance of good composition, colour harmony, tonal values and perspective. It further encourages the exploration of new ideas by examining other artists' work, and the development of personal style. Beautifully illustrated with 213 colour images.
