Abstract
Light is abstract. Light is difficult to describe with words. Unlike other pictorial motifs such as perspective, light depiction eludes fixed rules and defies straightforward measurement. This study presents a preliminary step towards measuring light information from paintings at scale. We use spherical harmonics to extract light environment features from depicted faces. Our initial evaluation assessed the model’s ability to accurately represent environmental lighting, using natural images with ground truth lighting information. To ev
