EXR

The EXR file format (OpenEXR) is an open-source and free image file format developed by Industrial Light & Magic in 1999. The format was originally developed to be a multi-channel, high-dynamic range raster image file format, which has evolved to include additional features over the years.

The format stores binary image data that can be either a 32-bit integer, a 16-bit integer, or a 32-bit floating point, which can also be compressed via a lossy or non-lossy compression method. The OpenEXR library is freely available to help developers implement the format in their applications.
