フィラデルフィア美術館さんのインスタグラム写真 - (フィラデルフィア美術館Instagram)「Examining a painting with a light source positioned at a shallow angle to the picture plane, a viewing method called “raking light,” highlights surface textures and deformations in the paint and canvas. (Swipe left) In this image, light positioned near the top edge of #Renoir’s “The Great Bathers” shows the severe forward curve of cracking, especially in the two left figures. Research indicates that this cracking relates to areas most heavily re-worked by Renoir. The relative humidity-related expansion and contraction of materials applied on the back of the painting in the 1930’s (done in an effort to address the cracks) may have made them more prominent over time. This condition posed risks for further cracking in the future. Assuring the attachment of the paint along the cracks and returning the paint to a more level state were major goals of the recent conservation treatment. Follow along as we reveal new insights from the process of researching, analyzing, and conserving Renoir’s “The Great Bathers”, now on view in The #ImpressionistsEye. #BehindTheScenes #RenoirConservation • Jason Wierzbicki, Conservation Photographer, and Kristin Patterson, The Joan and John Thalheimer Associate Conservator of Paintings, photographing “The Great Bathers” in raking light. “The Great Bathers,” 1884–87, by Pierre-Auguste Renoir, raking light view. • This conservation project and exhibition are supported by Bank of America.」7月13日 23時12分
