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...
متن کاملBasic calibrations of the photographic RGU system IV. Metal-poor subgiant and giant stars
We present a large grid of theoretical color-absolute magnitude and two-color diagrams in the RGU photometric system. The grid comprises wide ranges of stellar ages and physical parameters, and was computed using the YALE isochrones (Demarque et al. 1996) combined with the most recent version of the Basel Stellar Library (hereafter BaSeL) of color-calibrated theoretical model-atmosphere flux di...
متن کاملThe Eye and Photographic Lenses.
It appeared incomplete but formed a considerable segment of a circle. The above description applies chiefly to -the left iris. The departure from the normal. was less marked in the right eye. The writer believes this to be a case of congenital miosis of varying degree in the two eyes, and due probably, having regard to the findings of Holth and Berner, to developmental faults in the dilator mus...
متن کاملThe Origins of Photographic Discourse
In 1939, one hundred years after photography had been disclosed to the world, the thicket of received ideas about the medium's invention was so dense that even such an astute observer as Paul Valery could not extricate his thoughts from the tangle. For years the French poet and critic had been recording his unique perceptions of science, history, and contemporary culture. His commentary-filled ...
متن کاملSpatially 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...
