is there a possibilty to set the Aperture even on the FPV Cam? In very light conditions I can hardly see anything on the screen.

FPV camera allows you to control the aircraft from a first-person perspective, and helps you fly the aircraft safely when the camera isn't centered. Therefore, the settings cannot be adjusted.

what the FPV camera does I definitely  know ;-)
The question was if it is possible, to set the aperture in extrem light conditions on the FPV camera. We often shoot in snowy and sunny conditions and the drone pilot can´t see anything on the iPad Screen cause it´s totally overlighted.
