Hi, I did my first videos and photos today with my P3 Pro. All are overexposed. When I looked at the settings all I could see was the ISO, the shutter and the resulting over/underexposure EV when I changed any of the first two values. Does it really mean that I have to adjust shutter/ISO until I arrive at an EV value close to 0? Every cheap $50 point and shoot camera has automatic exposure and this expensive camera requires manual settings which could change any second anyway during filming? Am I overlooking anything?
