A new study reveals the science behind a 'trick of the light' that made high-profile photographs of a major piece of public art appear 'faked' despite the pictures being entirely genuine. Vision science researchers found images of the 75-meter long wind turbine appeared super-imposed because of a visual illusion caused by light reflections playing on preconceived notions about how objects are lit in natural settings, altering the object's shape to the human eye.
