I'm reposting what i posted over on BMCuser - the "after" images andrewmcmurry has posted above were some grades i played with that John posted:
"I've stayed away from posting about the camera since the announcement as much as possible because i know my thoughts will be seen as biased being that i'm involved with the cameras now, but i just wanted to say this short John shot back in Dec looks lovely and playing with the DNG's is a real treat. The grades i did back then he just posted was just me playing with various "looks" and obviously just one approach, but my opinion is you can definitely get that same 'mojo' that people love from the Cinema Camera, and personally i find it even easier to do so with the 4.6K. One difference though is that it's higher resolution with less noise, and that will "feel" different. But colour wise, DR, and motion i think it's strong, and flexible.
And to clear it up, yes i graded those frames of JB's back then from BMDFilm 4.6K, rather than 709. I believe John was just illustrating the "out of the box" look you could get. One goal with the new BMDFilm 4.6K is to make it easier to grade and get a nice solid base to grade further. I think the early footage from Kholi, Tom, and Roman shows this very well. They did very simple grades to show what the camera was capturing and you can see what a great starting point you have.
I hope it's okay with JB that i'm posting this, but here's one of the frames where all i've done is quickly add a curve to BMDFilm 4.6K. Personally i feel with the Cinema Camera it would take me much more work to achieve the same, which is why i originally turned my powergrades i used for that camera into a LUT to share online with people. Granted this is very nicely shot and what's in front of the camera and how you shoot it means more than anything else.
The classic 's' type curve i quickly did:

And the Result, just a curve on BMDFilm 4.6K without touching saturation or colour:

I feel like i could go anywhere from here with a look, or leave it as it is as a "neutral" look. Quite a few people over the last few months have been asking me if i've got LUTs for the 4.6K yet, but i'm not convinced they're even needed - as i said originally i shared my LUTs because i felt it was really needed to help people get somewhere good quickly. But not with the 4.6K. Perhaps i'll do some look type LUTs as i know they can be useful for some, i'm still undecided.
I'll go back to lurking now as i what i said with the 4.6K video i did at announcement still stands and so far the feedback from everyone who's shot with the camera is that they love it. Everyone's entitled to their opinions of course, but just like the original Cinema Camera you will want to learn how to get the best from it which i think people are starting to see the results of now.
Thanks to those who have been patient on this journey, i think it will be worth the wait.
