Scene rendering or the conversion of higher dynamic range input generated by a capture device or synthetically to a lower dynamic range for reproduction on a different device presents unique processing challenges. This paper summarizes and compares several techniques for scene rendering. The paper specifically addresses the issue of dynamic range mapping, independent of demosaicing, camera calibration, flare compensation, and white point estimation. There are a number of computational, image attribute, application and visual phenomena to be considered. Qualitative comparisons are also provided for several of the algorithms.
