Accuracy of localization of the radial position of a single stimulus was determined for various luminance-exposure duration combinations. Localization accuracy, provided the stimulus is seen, is independent of luminance and duration, but varies with the radial position of the stimulus. The results are discussed in terms of events critical to localization accuracy and it is concluded that the magnitude of photochemical events in the end organs does not limit localization accuracy for supraliminal stimuli.
