Tonight I flew over a field hoping to catch some pictures of deer and hogs coming out. There was plenty of light to see 300+ yards. I was about 100 feet up and the camera could barely see the sunset and when I panned down the the ground, it was totally blacked out. Should I set on manual and set the iso to 100? Would that lighten up the field of view? I just want to see - don't really care if I can take a picture or not! LOL
