About:
OpenEXR is a high dynamic-range (HDR) image file format and toolset developed by Industrial Light & Magic. It provides lossless storage of pixel data with higher precision and supports arbitrary channel layouts. This formula installs the core libraries and utilities for working with EXR images in visual effects and professional cinematography.

Key Features:

Half (16-bit floating-point), float (32-bit), and double (64-bit) pixel data types
Lossless compression with B44, PIZ, ZIP, and DWAA/DWAB methods
Support for arbitrary named channels and multi-part image files
Extensive C++ and Python APIs for integration

Use Cases:

VFX compositing and rendering pipelines
CGI and animation production workflows
High-precision imaging applications

Alternatives:

OpenEXR – Primary standard; this formula provides the official ILM implementation
libpng – Standard PNG format; lacks HDR support and limited to 16-bit integer precision
JPEG XL – Modern HDR-capable format; focuses on compression efficiency over VFX workflow features
