They make objects colse appear larger than real life and objects further away seem smaller than in real life. Wide lenses are typicall anything under 50mm. Now we can go back to wide, normal, and long. Is a lens is a 28mm lens, it means that the rear glass element is 28mm from the sensor. Since the sensor is smaller the lens has to be brought closer to it so the parallax is centered. To save on cost they make smaller sensors, as this is the huge majority of the cost of a camera body. The point of flip is called the parallax. A camera lens sees the image upside down and then flips it. I'm going to talk about full frame, because that is our reference point. If you were in front of two pillars you would notice them I've never been to a flat planet, so it might look different. Whether you think the earth is flat or round, it's going to look the same when you're a-sittin' on it! At least, I think so. Anyway, the point of the piece was that "The horizon looks pretty flat from here, no matter how you look at it." And then I tried to demonstrate why this would be true on a great big globe. NASA Sunsets: Have you ever watched a sunset If so, it is a compelling'duh' that the Earth is not flat. If there's distortion, wouldn't you say it's pretty negligible? And the Pano shot distorts things all over the place, but if you hold it steady, the horizon line looks *pretty much* like real life. From there, pitfalls can be easily dismissed like photos of the Earth. Pic 1 was actually angled lower than pic 2, but the line look the same. The reality, says Davidson, is that the flat Earth, sun, moon and stars are contained in a Truman Show-like dome. In fact, I did have the camera at different angles, but I (rather painstakingly) edited and cropped them so the horizon line matched. Fish-eye and other kinds, but I don't think my iPhone lens would. I think most lenses do not cause noticeable distortion. Couple points-not and expert, I could be wrong.
