Change your cineon to linear colorspace and then comp them together in
a compositor. EXR is just an image format. It's not magical or
anything. Maybe you could be more elaborate about what you don't
understand about exr?

Thanks for the reply..I'll try to explain better.
I understand that exr is just another file format and that it can
be treated as such. However what seems unclear to me is how this is
used in a production pipeline.
Typically, cineon are converted to linear format and stored in
16bit images. OpenEXR images are read as 32bit floats (by Shake
at least) and are quite slow to work with. Is this a price that
we have to pay? I tried to convert them to 16bit (to match the cineon
plate) however, they get clipped to 1 which makes it a useless
operation.
I guess my question is if people generally use them as 32bit floats or convert them to something smaller? And if so, how?
thanks!
