Abstract
The first quantitative measurements of skin pigmentation in man were made with the Hardy Recording Spectrophotometer by Edwards and Duntley (1) and depended on the light reflectance of the skin over the visible spectrum. Weiner (2) described the use of a portable EEL Reflectance Spectrophotometer and this instrument was also used by Barnicot (3) and by Harrison (4). A similar instrument was used by Lasker (5). In another paper a modified EEL reflectometer was described for quantitative measurements of skin pigmentation and the results of a comparative survey among some Asian and Pacific peoples were reported (Walsh 6).
