Abstract

Taylor’s data on the relative luminous efficiency of various filter colors at intermediate intensities have been examined for evidence of rod-cone interaction. Shorter wavelengths show relatively less evidence of combined rod-cone function, with the “transition range” limited to approximately one log unit of intensity. Longer wavelengths show evidence of a broader transition range. Relationships of this sort are of significance to the theoretical basis of intermediate level photometry and to the understanding of the transition between rod and cone vision.
