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. With ProEXR, artists working in Photoshop CS3 Extended can work with layered EXR files and save projects as EXR without collapsing layers. This one file can then be opened in digital compositing applications such as After Effects, Shake, Nuke, and Fusion. In many cases, OpenEXR is the only layered format the application supports. In After Effects, the 5 free plug-ins included with ProEXR take care of everything from OpenEXR file I/O, to extraction of channels into a composition, to automated project set-up from a layered file. They are open source to ensure that production facilities have unlimited ability to integrate After Effects with their OpenEXR-based pipelines. Built with the latest libraries from ILM, it lets artists read and write all OpenEXR compression formats, including the new B44 method which uses high-quality lossy compression to crush 32-bit float images to a fraction of their uncompressed size.
