Who applies the TTG label on a drone photo?
If only one person is responsible for the drone flight, that person would usually be “the photographer” whose name would back up the guarantee on a TTG-labeled photograph.
But if it is a larger drone operation and multiple people are involved, the person responsible for the photographs taken from the drone — a person that may not be the drone operator — would usually be “the photographer” whose name would back up the guarantee on a TTG-labeled photograph.
