Abstract

Coating specimens with ammonium chloride for photography has become the de facto standard for publication in palaeontological journals. However, it has several drawbacks such as the risk of damage to the specimen, and it requires access to a laboratory and a certain level of skill to carry out proficiently. This paper presents Reflectance Transformation Imaging (RTI) as a technique that can be carried out using digital photography equipment available to most researchers, museums or labs. The results of the process are compared with conventional photography, ammonium chloride coated photographs and 3D laser scans.
反射变换成像-一种可能替代氯化铵涂层的标本摄影
用氯化铵涂覆标本用于摄影已经成为古生物学期刊事实上的出版标准。然而,它有一些缺点,比如有损坏标本的风险,并且需要进入实验室和一定水平的技能才能熟练地进行。本文介绍了反射变换成像(RTI)作为一种可以使用大多数研究人员,博物馆或实验室可用的数字摄影设备进行的技术。该工艺的结果与传统摄影,氯化铵涂层照片和三维激光扫描进行了比较。
