This was not my test, it was conducted by Nick Paton, ASC whose opinion I would find valuable because of those three letters at the end of his name. I cannot definitively explain why it goes darker at +4 1/2 stops but I have two theories: 1) there is a natural clipping of the digital footage because of the overexposure and the camera responds by cutting out the image. Or (2) Paton said he did the test by over/under exposing the image then attempting to grade the images back to neutral. My guess is that it was so overexposed that when he attempted to grade it, there was no latitude to play with resulting in a pure white image (no grading) or a pure black image (attempt at grading).
I hope this seems clear and if anyone can illuminate this subject more and better, please chime in... |
