Description
Raster image stored in the OpenEXR format, a high dynamic-range (HDR) image file format developed by Industrial Light & Magic; supports multi-layer images, lossy and lossless compression, and 16-bit and 32-bit pixels; used for storing deep raster images for high-quality graphics; used by raster graphics editing programs and imaging applications.
It is an image compression codec file with the same quality as .jpeg, but that is ten smaller. It supports HDR (High Dynamic Range). SDR (Standard Dynamic Range), and WCG (Wide Color Gamut) images. Also, it contains both the image sequences and image items. The only pitfall is that a few applications support it.
