Any & All commercial aerial photography by drone may only be done by an FAA Part 107 licensed pilot. The definition of "Commercial" means that the end use of the photography or video is for commercial purposes. This does NOT mean that the imagery has to be paid for to be commercial.
It also does NOT mean you may shoot your own imagery and be lawful. If, for example, you shoot your own aerial video or photo for a property you have listed or for your own business, that imagery is deemed "commercial" by the FAA and you are in violation of federal law to use such imagery if you are not licensed.
DO NOT TAKE CHANCES. USE A LICENSED PILOT
Further, although not required by law it is recommended that any drone photography be performed by an insured pilot. Thus, if any injury or property damage occur during the flight you, as the person or entity that commissioned the aerial work will be covered for liability under that policy.
DRONE FLIGHT IMAGES IS FULLY INSURED AND FAA LICENSED.
