However, this brings up a question I've had for a while: What compression method does the default Photoshop OpenEXR plugin use? Is there a quick way to find this out?
It does Piz, which is the right choice for a default, particularly in Photoshop where photographic images are the norm. But I find that Zip16 is competitive in most cases and the clear winner for CG renders and things with areas of flat color. BTW, I verified Piz by opening a file in After Effects where my free AE plug-in has a little compression readout.
These days I'm also really loving the B44 + Luminance/Chroma combination. You can really crush the size of the file, usually without any noticeable artifacts. They also play back in real time using playexr.
It's lossy, so I probably wouldn't want to use it for archiving, but definitely for when I want to send an EXR through email.
