In the living room of a childhood friend’s home hung a framed aerial photo of their house taken from a plane. Their detached house stood alone on a large plot, separate from the rest of the semi-detached houses in our estate. Since the parents owned their own business, they had disposable cash to splurge on getting the image from such a height. Fast forward thirty years, and small battery-powered quadcopters with high-resolution digital cameras can create stunning aerial imagery, making a framed photo of your own house within reach of the average family. Note to self: frame the aerial photo of our house.
