I recently constructed a series of IDTs for three input Illuminants (D56, Tungsten and F3) for a set of ISOs on the Canon 650D for a Web Series ( JackAndCarmen.com ) . The IDTs are constructed as 3x3 Affine Transformations (Matrix Form). Chromatic Adaptation transformations were constructed as well.
The transformations were applied via color transformation language (ampas' CTL) and sony's OCIO configs. OCIO was used to construct 3D LUTs converting ACES to our calibrated monitors. ODTs were handled in Davinci Resolve. We originally tried the rec709 ODT, but ended up constructing our own LUT for ODT output (being piped through Davinci's internal RRT) for final web distribution (output to D65).
It was a great experience and I recommend anyone to construct their own IDTs per their own camera, because I've found (and it's been shown) that even between cameras of the same model that visibly detectable differences in sensors occur.
I plan on posting a detailed overview of IDT construction in the near future for those interested.
