Spatially Adaptive Photographic Flash

Using photographic flash for candid shots often results in an unevenly lit scene, in which objects in the back appear dark. We describe a spatially adaptive photographic flash system, in which the intensity of illumination varies depending on the depth and reflectivity of features in the scene. We adapt to changes in depth using a single-shot method, and to changes in reflectivity using a multi...

The HDR Photographic Survey

High-dynamic-range (HDR) imaging is one of the remaining frontiers for significant advancement in consumer and professional color imaging systems. Systems for the capture, processing, and display of HDR images are gradually moving from the research labs and specialized applications to more mainstream usage and impact on consumer photography. The HDR Photographic Survey is a research project and...

Art-photographic detail enhancement

We present a novel method for enhancing details in a digital photograph, inspired by the principle of art photography. In contrast to the previous methods that primarily rely on tone scaling, our technique provides a flexible tone transform model that consists of two operators: shifting and scaling. This model permits shifting of the tonal range in each image region to enable significant detail...
