Review of The relation between illumination and visual efficiency--the effect of brightness contrast

Abstract

Reviews the report, The relation between illumination and visual efficiency--the effect of brightness contrast by H. C. Weston (1945). The reviewer states that this report deals with two investigations on the effects of brightness contrast in relation to visual efficiency and was intended to test out the suggestion of Beuttell that if the relationship could be ascertained between size, contrast and brightness for satisfactory visibility, then the illumination suitable for the performance of any task ought to be capable of computation. According to the reviewer, these investigations were well designed and the analyses yield important data concerning the effects of brightness contrast, size of detail to be discriminated, and illumination intensities upon visual efficiency.
