Book excerpt: One of the attractions of painting outdoors is the challenge of capturing the spirit of a place – changing light, weather and transient conditions demand particular painting skills if they are to be interpreted effectively. Leading painter David Curtis works on location, in all weathers, observing and capturing the subtle effects of light and mood. Oil paint is as good for painting on site as it is for large-scale painting in the studio; it is remarkably responsive; can be applied in many different ways; and it allows time to assess and modify work in progress. In this fascinating book, David Curtis shows how he achieves such expressive and original results using drawings, paintings and stage-by-stage examples. He gives detailed explanations of his two main working methods – for plein-air paintings and for studio compositions – as well as plenty of helpful guidance and advice on choosing materials, exploring techniques, selecting ideas, composition, colour and tone and associated topics. Drawing skills and interpreting the qualities of light are other key issues that he deals with, while his wonderfully evocative landscapes, coastal scenes, interiors and figure compositions provide much inspiration.
