透光摄影在古书画修复与研究中的应用

透光摄影由常规可见光摄影发展而来，是针对中国古书画等能被可见光穿透的文物开发的一项无损摄影检测技术。通过实践发现透光摄影在古书画的修复与研究领域具有多项作用：观察书画命纸、背纸拼接等装裱情况；发现前人加固、补缀等修复痕迹；获取画面底稿内容；强化伤况视觉效果以便于分析文物伤况病害。透光摄影能够提供直观可靠的深层视觉信息，辅助修复人员了解文物内部状态，在古书画的修复与研究中发挥重要作用。

Application of light-transmissive photography in the restoration and research on ancient calligraphy and paintings

Light-transmissive photography, evolving from conventional visible-light photography, is a non-destructive photographic inspection method developed for ancient Chinese calligraphy and paintings and other cultural relics which can be transmitted by visible light. It is found through practice that light-transmissive photography has many functions in the field of restoration and research on ancient calligraphy and paintings:to observe the stitching of the first lining and the backing of calligraphy and paintings and other mounting conditions; to discover previous reinforcement, mending and infilling and other restoration traces; to acquire the underdrawing content of paintings; to enhance the visual effects of damage for its analyses. Light-transmissive photography could provide intuitive and reliable deep visual information and assist restorers to understand the internal states of cultural relics, playing an important role in the restoration and research on ancient calligraphy and paintings.
