One of the things I find interesting is how our trust in what we see has changed with the advent of the technological means to alter perception. No one would have questioned the authenticity of that photo taken by Ansel Adams in his time. We would have marveled at the wondrous circumstances that made such a photo possible.

I don't think anyone is questioning the authenticity of the original photo taken by Mark Bret Guma? Only the official theory that claims that light bending around the curvature is able to visually bring objects up from under the horizon by the tunes of many kilometers. I don't think most people can even imagine what it means for an object to be below the horizon by 5km. And consequently how unbelievable the official explanation is, especially that it is just an unproven theory without properly documented evidence.
