Original Note:
This picture was taken with a wide angle lens, which due to lens and barrel distortion, can make a convex curved line appear flat if it is under center frame. Footage taken with rectilinear lenses from high altitudes reveal Earth's curvature. https://flatearth.ws/fisheye-makes-flat http://walter.bislins.ch/bloge/index.asp?page=Lens+Distortion+and+the+Curvature+of+the+Earth
