OpenEXR - a high dynamic-range (HDR) image file format for use in computer imaging

• Higher dynamic range and color precision than existing 8- and 10-bit image file formats.
• Support for 16-bit floating-point, 32-bit floating-point, and 32-bit integer pixels. The 16-bit floating-point format, called "half", is compatible with the half data type in NVIDIA's Cg graphics language and is supported natively on their new GeForce FX and Quadro FX 3D graphics solutions.
• Multiple lossless image compression algorithms. Some of the included codecs can achieve 2:1 lossless compression ratios on images with film grain.
• Extensibility. New compression codecs and image types can easily be added by extending the C++ classes included in the OpenEXR software distribution. New image attributes (strings, vectors, integers, etc.) can be added to OpenEXR image headers without affecting backward compatibility with existing OpenEXR applications.

• IlmImf, a library that reads and writes OpenEXR images.
• Half, a C++ class for manipulating half values as if they were a built-in C++ data type.
• Imath, a math library with support for matrices, 2d- and 3d-transformations, solvers for linear/quadratic/cubic equations, and more.
• exrdisplay, a sample application for viewing OpenEXR images on a display at various exposure settings.
