Lightness, brightness, and anchoring.
The majority of work in lightness perception has evaluated the perception of lightness using flat, matte, two-dimensional surfaces. In such contexts, the amount of light reaching the eye contains a conflated mixture of the illuminant and surface lightness. A fundamental puzzle of lightness perception is understanding how it is possible to experience achromatic surfaces as specific achromatic sh...

which had Galileo among its members. He commissioned artists to record plants, birds and animals for his museum and a pictorial encyclopaedia that attempted to understand and classify both the natural and ‘man-made’ world. Alexander Marshal’s floral paintings were compiled at a time when the cultivation of gardens had become a pursuit of scholars and collectors, keenly interested in exotic spec...
متن کاملPerception of Lightness and Brightness of Achromatic Surface Color and Impression of Illumination
The relationships between lightness and brightness responses under the condition that achromatic "surface color " appears and the relationships between perceived illumination and brightness were examined. The Ss were required to make categorical judgments upon both lightness and brightness of the test patches presented on black and white backgrounds and upon the over-all illumination in the vis...
متن کاملLightness, brightness, and brightness contrast: 2. Reflectance variation.
Changes of annulus luminance in traditional disk-and-annulus patterns can be perceived to be either reflectance or illuminance changes. In the present experiments, we examined the effect of varying annulus reflectance. In Experiment 1, we placed test and standard patch-and-surround patterns in identical Mondrian patchworks. Only the luminance of the test surround changed from trial to trial, ap...
متن کاملLightness, brightness, and brightness contrast: 1. Illuminance variation.
Changes of annulus luminance in traditional disk-and-annulus patterns are perceptually ambiguous; they could be either reflectance or illuminance changes. In more complicated patterns, apparent reflectances are less ambiguous, letting us place test and standard patches on surrounds perceived to be different grays. Our subjects matched the apparent amounts of light coming from the patches (brigh...
