Andrew you are really a huge help for us all in making sense of this difficult trade. Thank you! I have a question about the dynamic range comparisons. Where do you decide the middle is for each camera? I assume you did that because neither the highlights nor the shadows match for any of the cameras. My thinking was that if I matched them all for the highlights or for the blacks, then you would see the difference at the other end of the curve. I know exposure is such critical thing, a third of a stop makes a big difference one way or another, so if the cameras don't match in the blacks, how can you decide if they are blowing out comparatively in the highlights?
