I've been doing a series of straight down still photos with my P4P. Most shots have been a long way away, so my only way to view the shots are through the monitor. All is good, except that I was recently doing a couple of nearby shots and realized that while I was seeing a straight down image on the screen, the drone was not straight above the subject. For example, I flew the drone at about 12' high, directly over a bush that was about 7' wide and the bush was not in frame. If I moved sideways about 7', the bush would come into frame. Any idea why this is this way and how to fix it?
