According to The Knot, drone photography started to take off (see what we did there?) in early 2014, but early adopters incorporated it into weddings a few years prior.
“A few wedding photographers over the past couple years have started experimenting with drones starting in sometime around 2013,” The Knot site director Anja Winikka told Mashable. “While it may sound a little out-there, drones are perfectly practical in that they can help capture photos and video footage that otherwise wouldn’t be possible.”
