I have been curios of what can happen when a movie is transported to BD, and show some of the problems that people complain about.
Not that I know much about it, but I did a search without too much results.
A cinema release is graded for a DCP/P3 colorspace. I did find a question/discussion of going from Rec.709 which is used for BD, to P3. http://forums.creativecow.net/thread/277/4821
Most replies state that there is not much difference.....and you can just apply a LUT to the material.
But one post disagrees; (my bolding)
I see some of you say there is no visible difference between P3 and Rec.709, which I disagree. I have involved a horror movie recently, grading in P3.
After it finished, I jump the cable to our Rec.709 Monitor, you will see dramatically difference. The green and cyan part turns to be totally blue, and there is huge contrast and brightness difference.
So, for those say no visible difference, are you sure you digital projector was set to P3, not Rec.709.
I then can imagine that if a movie like The Hobbit is just sent with a DCP/P3 colorspace from Weta to a BD authoring house in LA, and they just apply the "proper" 3DLUT (a conversion LUT) to the material.
Which might be fine for most of the scenes, but possibly change the colors dramatically for certain scenes.
If the BD authoring house is to lazy to check each scene of the BD/Rec.709 against the DCP-P3, we might end up with certain scenes on the BD with the Teal look.
Or that they do check, and then over-correct those scenes.
After following discussions between people that do color grading of movies for many years, I have very little confidence in that everybody follows the correct procedure or standard, because in these discussions the method each and one argue is correct are all over the place.
As I said; I don't have much insight in this, but it is a possibility more eager people can do some investigation into.
