Quantifying spatial, temporal, angular and spectral structure of effective daylight in perceptually meaningful ways
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
