In this thread we'll be examining the very first image taken from space from a V-2 Missile and the claim related to it: Source link of the Claim: https://aplanetruth.info/2016/08/11/first-ever-photo-from-space-shows-flat-earth/ You can find a recent article regarding the V-2 image here: http://earthsky.org/space/this-date-in-science-first-ever-photo-of-earth-from-space: The 35 mm camera has a normal lens, therefore flat earthers assume that since there is no curvature with a normal lens then the Earth must be flat. However: The aperture opening was f/5.6, with the shutter opening reduced to 17 degrees. The lens aperture is usually specified as an f-number, the ratio of focal length to effective aperture diameter. A lens typically has a set of marked "f-stops" that the f-number can be set to. A lower f-number denotes a greater aperture opening which allows more light to reach the film or image sensor. The specifications for a given lens typically include the maximum and minimum aperture sizes, for example, f/1.4–f/22. In this case, f/1.4 is the maximum aperture (the widest opening), and f/22 is the minimum aperture (the smallest opening). Here is how much curvature we expect to see using Walter Bislin's curvature calculator for an altitude of 104 607 meters ( 65 miles) with 35 mm lens. http://walter.bislins.ch/bloge/index.asp?page=Flat-Earth:+Finding+the+curvature+of+the+Earth Since Walter hasn't included lens aperture option in his program, I'm finding trouble the determine how much curvature there is for the camera specs of the V-2 missile.
