About 10 years ago I released ProEXR, a set of After Effects and Photoshop plug-ins for using multi-channel OpenEXR files. From the beginning, the core AE plug-ins were free and the source code was available. A year later the AE plug-ins started shipping with After Effects CS4, and they still do to this day. Eventually ProEXR AE was added, ProEXR EZ was made free, then Premiere plug-ins were added and later included with the program, free. I guess the only thing left to do is make the whole darn thing free. And so it is. (It's open source too.)
From the bottom of my heart, I would like to thank everyone who bought ProEXR over the years. Your support has really meant a lot, and allowed me to keep refining ProEXR into a stable product used by artists and installed in studios all over the world. All those who will use ProEXR in the future owe you a debt.
To be candid, part of the decision to make ProEXR free was driven by the emergence of another free Photoshop plug-in with a strikingly similar feature set. It looks nice, check it out.
Thanks again, everyone. Enjoy!
