How a Fish Eye Lens Really Sees the Horizon

Posted by K R on

Hi there, going back to the flat earth debate some time ago there were claims regarding how photos taken with a fish eye lens look and how they would be responsible for the curvature of the earth in those photos. Today I finally had an opportunity to take a camera up in a helicopter with a fish eye lens. The attached photos are take with a Nikon 10.5mm lens at approximately 3000 feet above sea level. The first image (above) was taken with the horizon in the centre of the frame. Second:
Taken with the horizon at the bottom third point of the frame. Taken with the horizon at the bottom third point of the frame.
Third:
Taken with the horizon at the top third point of the frame. Taken with the horizon at the top third point of the frame.
There is no post processing done to these photos. As you can see the only time the lens causes an obvious distortion to the horizon is when the camera is pointed downwards so the horizon is above the middle of the frame, otherwise it’s flat or curved upwards. Make of these as you will, I was hoping to get them on the site to add to the debate. Cheers, Canuck Chris
