Optimal exposure control for high dynamic range imaging

A common technique used to acquire high dynamic range image data is that of exposure bracketing--short exposure times are required to capture bright regions of the image without saturation, whereas long exposure times are needed to capture darker image regions effectively. This article describes how to take into account the statistics of the photon arrival process to derive optimal exposure control for maximizing signal recoverability in high dynamic range imaging.
