This is Flaat
Flaat is a suite of picture styles for Canon and Nikon DSLRs.



Cleaner images
Flaat aims to deliver less noise in the final (graded) images than Cinestyle.
It tries to achieve this by using a bigger part of the codec's color space.



Easy to grade
By giving a near-log light response, Flaat aims to be as easy to grade as possible.
Also, by being based on Portrait (instead of Neutral), it tries to make it easier for you to get nice skin tones in your final images.



Better control

Flaat includes 3 picture styles, all with the same colors and a near-log response to light, but spread over different latitude:
Flaat_10 gives a bit over 10 stops of DR (just as much as CineStyle)
Flaat_11 gives around 11 stops of DR (more than any other option I've tested)
Flaat_12 gives more than 11 stops of DR (use with lots of care: it can be very noisy)
The general advice for clean images would be: use the narrowest Flaat picture style that records enough DR for your shot. If Flaat_10 doesn't give you clipped highlights or shadows, that route will lead to less noise and smoother gradients than using Flaat_11.

Also... The Flaat suite for Canon DSLRs is based on Portrait, for better skin tones, but this has some downsides (some color shifts, e.g. blue goes a bit towards cyan) that some people would rather avoid. There's a second suite of Flaat picture styles, based on Neutral, that has the same near-log light response function but avoids this color shifts. I'd rather have nice skin tones than correct blue, but it's your choice.



Too complicated?
Don't like having to choose from so many options? Just use Flaat_10: that's the workhorse.
