National Museums Scotland A1904.160 Shirt [quillwork detail under Reflectance Transformation Imaging]

NMS Catalogue Description: Tunic: North America, Canada, Plains, Blackfoot Reflectance Transformation Imaging dataset of quillwork detail taken on project visit to National Museums Collection Centre, Edinburgh September 2021. Comprising 88 jpeg files and finished .ptm file. RTI is a computational photographic method that captures a subject’s surface shape and colour and enables the interactive re-lighting of the subject from any direction. RTI also permits the mathematical enhancement of the subject’s surface shape and colour attributes. The enhancement functions of RTI reveal surface information that is not disclosed under direct empirical examination of the physical object. RTI Viewer and Builder are freely downloadable from Cultural Heritage Imaging Website.

NMS 目录描述：短袍：北美洲，加拿大，大平原，黑foot族。该数据集由2021年9月于爱丁堡国家博物馆收藏中心项目访问期间拍摄的羽饰细节的反射变换成像组成，包含88个JPEG文件和完成的.ptm文件。反射变换成像（RTI）是一种计算摄影技术，能够捕捉物体的表面形状和颜色，并允许从任何方向对物体进行交互式重光照。RTI还允许对物体的表面形状和颜色属性进行数学增强。RTI的增强功能揭示了在直接实证检查物理对象时未被披露的表面信息。RTI查看器和构建器可从文化遗产成像网站免费下载。
