Our website provided a free download of ProEXR 2.5 for Mac. This software for Mac OS X was originally created by fnord. The application is categorized as Design & Photo Tools.
From the developer:
ProEXR is a set of 6 plug-ins to provide complete support for the OpenEXR file format in Adobe Photoshop and After Effects. Both Adobe applications include basic support for OpenEXR, but ProEXR provides access to important features of the format including multiple image layers, preservation of color space information, and choice between all compression options available in the latest OpenEXR libraries.
