OpenEXR is a high dynamic range (HDR) image file format developed by Industrial Light & Magic for use in computer imaging applications. It includes support for 16-bit floating-point pixels (compatible with NVIDIA's Cg shader language "half" datatype), several lossless compression algorithms, and extensible image metadata attributes.
