Now that more and more people understand what drones are, what they do, and what they are capable of, the neighbors around the homes you photograph are becoming more sensitive about having a drone near their home. The video to the right shows a great example of someone who doesn't like a drone near his home.
So you may want to think twice about using a drone to shoot elevated front exterior shots unless it is absolutely necessary. Of course, there are some properties where drones are essential for getting the best shots but for the majority of low-end properties that aren't on acreage or near a waterfront, the old fashioned elevated shooting techniques like poles, giant tripods, and ladders may save aggravating the neighbors.
Another alternative would be to talk to all the neighbors around the property you are going to shoot and let them know when and where you are going to be flying to assure them your intention is not to photograph their home.
Has anyone had trouble with this kind of thing?
