... Debattista Alan Chalmers Advanced High Dynamic Range Imaging High dynamic range (HDR) imaging is the term given to the capture, storage, manipu- lation, transmission, and display of images that more accurately ... discipline of high dynamic range imaging that combines photography and computer graphics. Historically, traditional wet photography managed the recording of high dynamic range imagery through ... We successfully showed that in images with limited dynamic range, our simu- lations were more accurate when compared to a real scene than previous heuristics, but we left the high dynamic range problem hanging. Through...
