In our former study, we proposed Virtual Luminance Distribution Method (VLD Method), a method for estimation of environmental brightness based on perceptual determinants of environmental brightness, and showed that VLD Method is valid for environmental brightness estimation of a model-space. In this paper we performed an experiment using real-size experimental booth. In the experiment, subjects evaluated environmental brightness for various lighting conditions of the booth. Our analysis indicates that: 1. The estimated environmental brightness by the VLD method has rather high correlation with the psychophysically evaluated environmental brightness. 2. The VLD Method estimates the effect of local lighting on environmental brightness with a fair degree of precision.
