My discussion is about how to create to creative and stylized 3D LUT.
Our film is in the postproduction，the director hope that the final color would be seem a older film（exactly it should be a certain way of printing ）。so first we need to calibrate the projector。it could produce a 3DLUT
now my problem ：
1.Could we simulate the color of older film based on a the calibrated 3DLUT and how to achieve it ？
2.what kind of problems would we encountered when we used the RED materials to simulate Film？
you can create 3dlut's with software and then use it in the projector too, but why wouldn't you just send color correction to post and burn in the CIE XYZ color space 2.6 gamma so that the film will work in any dci theatre without needing to hand off special instructions and applying extra luts?
1) You can try something like http://filmconvert.com/default.aspx if you're looking for a very calibrated workflow. Alternately, you can design your own LUTs in color grading programs by grading a few of your "hero" shots to emulate the look of your target film.
2) Hard to say. It depends on the look you're trying to achieve. In general, with any digital footage, you won't get as subtle shadows or highlight rolloff. You have to be aware of how aggressive contrast adjustments can be.
