I'm stupid. What is .exr?

Hey everyone,

I just want to know what .exr can do or does for your composite. What is the general use for .exr-files?

CHEERS!

"OpenEXR is a high dynamic-range (HDR) image file format developed by Industrial Light & Magic for use in computer imaging applications."

There's a lot to say...better read for yourself.

You're not stupid; you asked because you don't know and questions are always welcomed in here. My teacher always said "it's better to ask a dumb question during lecture, than to be dumb on the test". You ask because you don't understand.
