So when my Post Supervisor told the DP it was better to shoot Rec 709 for green screen the response was, "Why would I want to give you less information."
Clearly the DP doesn't really understand the reality of what shooting Log actually does to the information.
As has been pointed out in this thread shooting log sacrifices chroma info for luma info, if I understood that correctly.
In my mind shooting log packs more latitude of exposure into the limited space of the codec and it also sacrifices information detail in bright areas to give more detail to the darker areas because the human eye is less sensitive to detail in the highlights.
So in a nutshell there is only so many steps in 10 bit and shooting log compresses greater latitude into a smaller space that will then be decoded back out to the as much latitude as the deliverable specs allow. But putting more range into less range and then stretching it back out is adding quantizing issues etc... Why is this such a misunderstood concept?
