HDR Image Capture

HDR images may be captured from real scenes or rendered using 3D computer graphics (CG) techniques such as radiosity and raytracing. A few modern graphics cards are even capable of generating HDR images directly.

A camera is essentially an imperfect device for measuring the radiance distrubition of a scene, in that it cannot capture the full spectral content and dynamic range. The film or image sensor in a conventional or digital camera is exposed to the color and dynamic range of a scene, as the lens is a passive element that merely refocuses the incoming light onto the image plane.

OpenEXR Format - The EXtended Range Format (.exr)

The EXtended Range format (.exr) was made available as an open-source C++ library in 2002 by Industrial Light and Magic. It is based on a 16-bit half floating-point type, similar to IEEE float with fewer bits. Each RGB pixel occupies a total of 48 bits, broken into 16-bit words. The Half data type is also referred to as S5E10, for "sign, five exponent, ten mantissa." The OpenEXR library also supports full 32-bit/channel (96-bit/pixel) floats and a new 24-bit/channel (72-bit/pixel) float type introduced by Pixar.
