yes, but that's not exactly what Corey said, is it? even with real life cameras you can do push/pull/cross processing - I mean fair enough, that has only limited application in regards to digital cameras but even that shows that with such a simple technique you could take your final work very very far. I am just tired of the fanaticism in the cgi world, what is right/wrong workflow and what sort of standards we all should be using - I agree as to that you should set your exposure to be somewhat correct but constantly sampling your pixels to be exactly 165,165,165 is a pure OCD. As Dave said we are not limited by any of the real life constraints (although we can benefit from them) so why is everyone suddenly taking this scientific approach to imagery? I even struggle with LWF to be honest - the only real life scenario I can think of where it makes sense is when you need to have all your input/output consistent across a few departments - but if not then why not take it further and see what happens? we have all this options and possibilities available at our disposal to use, misuse and even exploit but barely anyone seems to be doing that. photographers are using correct exposure and a few bounce cards because they have to, we can and should be doing whatever we want. if I feel like I need 25 spot lights to light one chair in the middle of the living room, I will.
tl;dr experiment goddamnit
