|
| Authors: | G Garrard G A Harrison J J Owen |
| Abstract: | A study has been made of the comparability of the two reflectance spectrophotometers, EEL and Photovolt, which have been most widely used for measuring variation in human skin colour. From samples of Negroes, Indians, and Europeans measured with both instruments various conversion equations have been calculated using a “least squares” method. |
