Abstract

High-dynamic-range (HDR) images can be created with standard camera hardware by the capturing and combining of multiple pictures, each sampling a different segment of the irradiance distribution of a scene. This seemingly straightforward process involves several important steps, which will be the focus of this chapter. We start by examining the problem of selecting the set of exposures that properly measures the full dynamic range of a particular scene, a process known as metering for HDR. We then describe how to perform radiometric ...
