What is an EXR file?
An EXR file is a raster image stored in the OpenEXR format, a high dynamic-range (HDR) image file format developed by Industrial Light & Magic (ILM). The EXR format supports multi-layer images, lossy and lossless compression, and 16-bit and 32-bit pixels.
In 1999, ILM developed the OpenEXR image format. In 2003, the company released the format to the public, along with an open-source software library that could be used to create, edit, and process OpenEXR images. OpenEXR images are saved as EXR files.
Computer graphics professionals, such as visual effects artists and animators, are most likely to encounter and use EXR files. The EXR format is designed to provide graphics professionals with the ability to create high-dynamic-range scene-linear images. Notably, EXR images may include multiple channels of different pixel sizes, as well as multiple points of view for the same image.
How do I open an EXR file?
You can open an EXR file in Adobe Photoshop (Windows, Mac). To do so, you must install the fnordProEXR plug-in. You can also open an EXR file in GIMP (cross-platform), though that program can open only single-resolution, nonlayered EXR files.
