Perhaps you are considering Oscar's text? :-
Code:
Set "Camera Angle" in the Configuration tab
Largely a personal preference, I usually set it to half of my actual camera angle, e.g. for 20 degree camera angle, I’d set it to 10.
This mixes pitch and roll into the yaw movement, it makes yaw control more natural and requires less stick input.
Some people prefer to turn this off for Acro mode, you can do so by enabling “FPV Angle Fix” in the modes tab, assign the same switch you use for Angle mode.
This and other text refers to what can be also direct CLI typed instructions. Most people I know have only ever left that area of Betaflight on default.
A word of caution, while its best to read up and then experiment to find ALL the Betaflight settings and so determine what is best FOR YOU, be aware that for example with increasing camera angle / greater speed vision ability you can reach a point where landing at low speed/near hover is made more difficult as you will have little ground view. As with pretty much all Betaflight settings, little changes and testing, then more, then find your limit and back it back a little.
If you have watched DRL or one of the TV/Online race series you will have seen they use extreme camera angle, but they are taking off from angled launch pads and "landing" is a flat out crash into a netted catch pit!
