Recently I started filming with my Nikon D800 using Color Profile Flaat_12. I used an 50mm at F1.4.
As I looked trough my footage in the camera viewfinder, i found some defocused subjects having an unusual look. I tought that, due to the size and detail of the screen, that when I transfered the files to a better screen, those "color smudges" would have disaperaead and contain the right information.
1- Loss of detail in the ponytail
2 - Loss of detail in the "smiling guy" face
As you can see in the attachments i´ve uploaded, there are some loss of color definition and detail in the defocused subjects. As I try to color grade them, I cannot get any information.
Is it always like that when you use a low F/number?
Do any of you know how to avoid this kind of result?
In my opinion, the forehead of the smiling guy in your second picture is simply blurred because you are shooting at 1.4.
With a 50mm lens with your camera shooting at 1.4 and if you are standing 6 feet away from the point you are focusing on, only things 2 inches in front and 2 inches behind that focus point will be sharp.
The pony tail might be the same reason - if you are focused on the back of the head of the girl it is possible that the back of the pony tail is more than 2 inches away and is therefore blurred.
Because of the exposure level of the images I can't make out the "color smudges" you refer to.
I see what you're talking about and I can see how it would be potentially distracting. I haven't shot with the Flaat_12 profile specifically, but I have shot with some other ones that flatten the image (Technicolor CineStyle and another one I think.) While shooting flat so you have more room in post is an ideal situation, I ended up finding it to be a bad idea on DSLR's. With an 8-bit color depth on highly compressed H.264 footage, the footage always falls apart in several different ways when any color is applied.
The picture style I use now is the Lotus Film Picture style
