I mostly photograph for real estate agents and the press, but has recently been asked if I can film a roof on a church before a final inspection. Have never done this before, and wondering if there is something I should consider, think of.. What I think of is to pull down the gain, so it is not as quick in acceleration. ATTI? But perhaps become dangerous if you fly close and there comes a gust of wind? Will work my way from side to side up to the ridge and then vertically up and down the church tower. It should be the easiest flight without risking to crash into the church?
