There were a few emails that went out last week about writing OpenEXR 
images.  I'll mail them to you privately.

We'll probably set up a FAQ, at least, for these sorts of questions.  As 
Florian said earlier, we'll wait until the file format stabilizes before 
we write any formal specs or documentation.

Yeah, those functions are for display, but if MAX expects image data to be 
"cooked" for display, you'll need to apply at least a gamma curve to get 
them into the display space that MAX expects.
