(TU Delft Human Information Communication Design) Wijntjes, M.W.A. (TU Delft Human Information Communication Design) Eisemann, E. (TU Delft Computer Graphics and Visualisation) Pont, S.C. (TU Delft Human Information Communication Design) Date 2023 Abstract We present a method to capture the 7-dimensional light field structure, and translate it into perceptually-relevant information. Our spectral cubic illumination method quantifies objective correlates of perceptually relevant diffuse and directed light components, including their variations over time, space, in color and direction, and the environment’s response to sky and sunlight. We applied it “in the wild”, capturing how light on a sunny day differs between light and shadow, and how light varies over sunny and cloudy days. We discuss the added value of our method for capturing nuanced lighting effects on scene and object appearance, such as chromatic gradients.
