Abstract: Some experimental data are displayed, indicating how tha ratio of (photopic) luminances at the brightness match varies when stimulus size is varied, at various retinal locations. stimuli giving mainly an achromatic contribution to brightness (white, yellow, greenish) are compared to a red stimulus which is expected to produce an extra brightness signal. The photometric implications at the site of the “receiver unit area2 are discussed.
