Two weeks ago I shot a video that required me to fly over people. We had 20 people or so in this group (friends of friends). Before the flight I had everyone sign a release form and a liability waiver. We discussed the dangers of having a drone overhead and all was well. Video turned out great! I now have a job of shooting stills for a soccer camp tomorrow. I've explained how I would not be able to fly directly overhead. The waiver thing came up in the conversation and the assisting photographer explained how these kids are already under a waiver and release through their soccer organization. Thoughts?
