@anarkzie Some laughs?

@Mikleo why do they think NASA are doing this, like what would NASA have to gain?

Maybe it was MS Painted. ^_- (why the downvotes, btw? People are offended so easily nowadays... It's not the denial of Earth's shape that this comment was about. Tsk tsk tsk)

Seriously check your facts why are people so untrusting I get it many people lie but cant we just all agree on one thing that the world is ROUND

Actually, I'm embarrassed to admit it, but I used... Microsoft PowerPoint. I know. I need to upgrade.

what if he used GIMP/Mypaint/krita.... etc ?

Ok so lenses fall into three categories. Wide, normal, and long. I don't know much about camera phones. When I shoot I only use SLRs. I'm going to talk about full frame, because that is our reference point. 35 mm. A camera lens sees the image upside down and then flips it. Just like our eyes. The point of flip is called the parallax. To save on cost they make smaller sensors, as this is the huge majority of the cost of a camera body. Canon has 1.3 croppers and 1.6 croppers. Since the sensor is smaller the lens has to be brought closer to it so the parallax is centered. Now back to the full frame, 35 mm. Is a lens is a 28mm lens, it means that the rear glass element is 28mm from the sensor. Now we can go back to wide, normal, and long. Wide lenses are typicall anything under 50mm. Wide lenses have distinct distortion. They make objects colse appear larger than real life and objects further away seem smaller than in real life. If you were in front of two pillars you would notice them

I am not trying to look smart, but... I have been in CN Tower (pretty high that thing) where you can make a 180* panorama and the curve of the earth is noticeable. I don't know why, i am not very good at science, but the higher you are, the faster you can realize that the earth is NOT FLAT. While you're in a plane, you can't realize this (don't know why, don't have an answer...)

2. Bend toward each other at the top. They warp perspective the same way a convex mirror does. Normal lenses do not create distortion. This is a 50mm. If you hold an slr with a 50mm on it up to your shooting eye and have your tracking eye open, all objects are the same size. Long lenses compress distance. They make objects appear closer to eachother than in real life. A flower 10 feet in front of a subject will make them look much closer together depth wise than in real life. Sorry to nerd out, but you did.

Ok fine but how come the horizon is at eye level even at 120,000 feet and fish eye distorted lenses where New Mexico is made to appear like it’s half the Globe

Well, when I take a pano shot, what I do is hold my body kind of stiff and shuffle my feel in a little circle. That's usually the best way to get the picture I want.
