Paperback. Etat : New. Print on Demand. This book examines an interlaboratory comparison of photometry measurements involving color differences. The study looks at the agreement among observers and laboratories in measuring the transmission of glass screens and the candlepower of tungsten lamps at various voltages. The results show that each observer maintained a consistent criterion within their laboratory, and each laboratory showed good agreement with the mean of all laboratories, regardless of the type of photometer used. Importantly, the measurements also align closely with average eye perception, as determined in a separate study involving a large group of observers. These findings highlight the importance of careful observer selection and standardized conditions when establishing photometric standards involving color differences, especially for precision measurements. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N� de r�f. du vendeur 9781333935320_0
