Computer rendering tools have traditionally allowed an artist infinte creative space for image generation, and as such, computer-generated artwork has been of subjects which do not require any grounding in physical reality. While this is surely a benefit of working in the digital realm, it also allows creation of images that, by lack of familiarity and expected visual cues, can alienate a viewer. Radiance's lighting algorithm returns these cues to an image, allowing a stronger and more visceral connection between the viewer and the image, while still allowing an artist the creative space of a sculptor and photographer. In this talk I will present techniques that have been developed over the past five years of using Radiance to make digital art.
