Performing psychophysical experiments to investigate lighting perception can be expensive and time consuming if complex lighting systems need to be implemented. In this paper, display-based experiments are explored as a cost effective and less time consuming alternative to real-world experiments. The aim of this work is to better understand the upper limit of prediction accuracy that can be achieved when presenting an image on a display rather than the real-world scene. We compare the predictive value of photographs and physically-based renderings on a number of perceptual lighting attributes. It is shown that the photographs convey statistically the same lighting perception as in a real-world scenario. Initial renderings have an inferior performance, but are shown to converge towards the performance of the photographs through iterative improvements. © (2013) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
