The Impressionists were not only pioneers in style, they were first and foremost innovators in technique. Important information on Impressionist techniques has recently emerged from technical and scientific studies (stereo-microscopic, infrared and ultraviolet radiation and x-ray) of pictorial supports, constituent concepts and work methods; pigments and connecting elements, such as the interaction between the surface texture and painted effects. Painting Light is not just another catalogue on the Impressionists. It provides a panoramic view of the Impressionist and post-Impressionist pictorial techniques in 60 masterpieces by Van Gogh, Sisley, Gauguin and others.
