You asserted that, yes.
Or a halfway decent photo editor. Heck, the free one that I have for my Chromebook can do it with some tweaking. I guarantee you Adobe could. Granted, if you try to straighten out a picture of the Earth so that the horizon is flat, it'll distort everything out of proportion, but that should tell you something.
Type in 'reversing fisheye lens' into Google. It's not hard.
It's not like the effect is complicated.
Hypothetically. Just spitball. What would you accept?
I assume you don't accept the satellites which take publicly available pictures of the entire Earth every few minutes, for...reasons.
And there we go. When it supports a flat earth - or you think it does - you have no problem with photographic evidence.
Why is it that you want, so badly, to pin a FE believer button on my chest? Would that give you closure? Would that help you sleep at night.. Or would that just give you more "right" to jab me with jibes and name calling.
Let me spell it out... OK?
I am not convinced of the shape being globe or Flat..
NO picture, trying to prove either has changed that..
It's very easy, in fact can be done accidentally, to shoot a picture of a horizon with a curve.. absolutely no further manipulation need to be done.
It is very difficult to shoot a view of a curved horizon, if that is the actual state of it, and show it to be flat, without digital manipulation.
So, no photograph has convinced me of either... Certainly not the fake fish eye NASA shots that they keep vomiting out and people keep standing on like they are some Holy grail.....
So, live out your fantasy of my view, what ever you want.. Ridicule me for not accepting obviously fake pictures and video that an 8 year old can do.. Stick what ever name on me that helps you have a good meal... enjoy your realm of unreality... you certainly don't want to risk having your eyes open to the real one...
