Earth from space NO FISHEYE

is this the thread were you say "fisheye" every time you spot curvature?

This is the thread where uneducated fucks don't understand optics and the fact that their own goddamn vision is "fisheye" if "fisheye" means "not orthographic".

Obviously feet in that case.

While using SI units is preferable, context should show that it's ft.

Well there is clearly no lens distortion that would account for such a strong curvature and it's clealy not flat.

Pretty much this.

The "fish-eye lens" argument stops working at such high altitudes. Just the fact that people aren't calling it a convex lens is pretty indicative that nobody that knows their optics is making the argument.

enlighten me

I'm not going to tech you how lenses work. That's the job of your educational system, (or the person who homeschools you, if that's the case)

Go here: passmyexams.co.uk/GCSE/physics/concave-lenses-convex-lenses.html

and play around with lenses and geometry if you must confirm.

bump

But why?

Just let it die
