@PBD: Your photos of the 4WD are much more brightly exposed. I'd be willing to bet little if any data in the shadows is buried in the read noise, which means the image isn't DR limited. That's another point no one seems to get, but whatever, nothing but two RAW files, one from a 5D III and one from a D800, that I can upload so you guys can compare yourselves, is ever going to settle the issue.
Of course it is DR limited, I exposed so I didn't lose the shadows (I do have some experience exposing for Canon sensors ), I completely blew the sky.
Hmm, maybe I misunderstood. Did you recover the sky? Or replace the sky?
I replaced it, it took 15 seconds and a further couple of minutes to make look OK (which I don't have on my laptop). I suppose my point was any picture that I want to display I am going to spend a few minutes on as a minimum, and I can deal with a blown sky in no time, anything I am going to print I will take much more time over anyway. It really doesn't make any difference to me what file the info is on, I can make it work fast.
I think there is something to Daniels comments, whilst you can lift the Exmor shadows without the noise of the Canon sensors, there still isn't any detail there, and I think you are thinking they will give you more than they actually will. I know when you do first try one out you will be amazed, but after time you will question the results you get in a different way.
Yes I agree more isn't a bad thing and the shadow noise in Canon's is a weak point, but as all solutions are invariably a compromise, I can deal with that as the biggest compromise in my system.
