Client would like his 700 acre landfill flown in the next couple weeks. With less than optimal lighting conditions in the northeast US this time of year, I want to make sure the settings are correct to capture the site in 1 visit. Last year I started the mission using auto white balance but had to cancel due to slow air speed. I then used aperture priority and an ISO of 400 with decent results. I typically fly at 380'AGL and get a GSD of around 1.5".
Is the ISO adjustment the way to go, or should I look at other settings.
