National Museums Scotland A1904.160_Shirt (full capture under Reflectance Transformation Imaging)

A1904.160 NMS Catalogue Description: Tunic: North America, Canada, Plains, Blackfoot Reflectance Transformation Imaging dataset of full shirt taken on project visit to National Museums Collection Centre, Edinburgh September 2021. Comprising 143 jpeg files, assembly files and finished .ptm file. RTI is a computational photographic method that captures a subject’s surface shape and color 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.

A1904.160 NMS目录描述：长袍：北美，加拿大，大平原，黑脚人反射变换成像数据集，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全套长袍构成。数据集包含143个JPEG文件、汇编文件以及完成的.ptm文件。反射变换成像（RTI）是一种计算摄影方法，能够捕捉被摄物体的表面形状与颜色，并允许从任意方向对物体进行交互式重新照明。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考察物理对象时未被揭露的表面信息。RTI查看器和构建器可从文化遗产成像网站免费下载。
