And just a public service announcement --
Yes, fisheye lense distortion is DEFINITELY a thing. I'm not just throwing that out there because I was born into Flat Earth and brainwashed with Flat Earth propaganda for decades. Quite the contrary. I was literally brainwashed with Globe propaganda for 4 decades. I busted out of it.
You ALWAYS have to ask yourself: is it the "curve of the earth"? Or a FAKE curve? And no, it's not some convenient device to dismiss evidence I don't like, some confirmation bias, or some such.
Because you CAN figure out, with logic, if the curve is real or not.
ALWAYS COMPLETE THE CURVE. How big of an earth results? And what would be seen on this extrapolated "globe earth"? Would it be big enough to contain the continents we KNOW exist?
Look at these pictures. Does a globe containing approximately 1 U.S. state seem reasonable to you? Sure doesn't to me.
The world has several continents -- not just the state of Arizona.
