I have some problems with Flat picture control presets and my Nikon D7100. This camera is known for horrible banding when lifting shadows too much, and it shows banding always, even at ISO100 when using any of the Flat picture profiles I have.
It is somehow confusing for me, because it is logical that presets do not interfere with sensor and it can not amplify noise or signal, it just reveals it because of the curve applied in the profile, but still my footage is horrible even in the studio with good light.
Here is some example:
I always expose for the highlights, and here some deep shadows and blacks can be solved by applying S curve, but noise and banding is everywhere so it is impossible to mask everything with contrast, even if I make it very strong.
Is there some general rule about Flat picture profiles, where to use them, and where not to use them, I am very confused now?
