>Anyway, I was wondering how target colorspaces are handled in IIF? Assuming you would want your footage to have more or less the same look on all delivery >formats (DCI P3 XYZ, HD Rec709, sRGB, Film Log...)
The IIF ACES workflow calls for an "ODT" that is added to the "RRT" for real world applications
ODT = Output device transform ie your display
RRT = Reference rendering transform ie the look that should be achieved on your display
In essence this part of the workflow is similar to the current DI workflow which I describe at http://www.finalcolor.com/CMS.htm in which a target profile is combined with a display profile to create a LUT for grading. The display profile is then switched to standard profiles to create a transform for alternate color space versions.
Also read Mike Mosts blog http://mikemost.com/?p=235 for a good overview of what benefits ACES offers
This is also explained in my Display Calibration and Emulation classes
