Luminance, Reflectance, and Chromaticity from RAW Scene Capture

This paper measures the effect of increased dynamic range on the accuracy of scene radiance measurements made from photographs of scenes. The experiment uses a constant scene with constant illumination and constant camera exposure settings. A small lightbox in the scene had luminances that varied from off to 19200 cd/m2. It varied the dynamic range of the scene, while leaving the rest of the scene radiances unchanged. Optical veiling glare altered a image's radiances on a camera's image plane. The camera's optics spread some of the light from the lightbox into the rest of the camera image. This article measures how optical glare affects camera-based calculated luminance, reflectance, and chromaticity values.
