It is a popular belief that people appear to be about ten pounds heavier in photographs or videos in comparison to what the normal human vision perceives. One of the latest videos published on Scishow’s Youtube channel explores this myth by taking a closer look at the phenomena from a scientific point of view.
Based on the in depth video explanation, there are two main reasons affecting the heavier look of people captured by the camera. The two reasons are; the monoscopic vision of a single lens used in a camera and; the choice of different focal lengths of the lens used affecting varying perspective outcomes.
