https://cdn.discordapp.com/attachments/561988982884270088/616011193735446529/contrast.gif So, I made this gif from a YouTube video. I don't know if there's a common argument to this or not, so that's why I'm here. Just to get an answer and be happy.

It's regarding weather balloons and curvature.

Two frames.

Yeah, I only added a horizontal line.

Anyway to describe the picture I made... You will notice that the horizon changes position at different heights, and that despite going below the horizon line, it doesn't concave like you'd expect if you were on the surface.
So what's the argument for this?

Yup. That was the purpose.

I already confronted a flat earther with it, and all I got in return was dead silence. I'm hoping someone here will actually say something.

Yeah, it's annoying when they do that. I was tempted to make a 3D sphere model with fisheye lens and make a gif that shows the problem with flattening the horizon that way.

So... Does anyone have a comment on the picture I posted? Need sources? Details? Anything?

It's a gif where I demonstrate what I'll just say is a curvature of some sort.

Taken from a weather balloon video on YouTube.

The horizon line was added in myself, and the two pictures are from the same video.

The image was also squished horizontally, as it removes any existing doubt a person might have if the curvature changed or not. I have the normal unsquished version too if you insist I post it.

Thinking about talking more. That's all.

I think I said everything I need to.

I agree. So, what about mine?

Two screenshots taken from the same video. Though perhaps the smudge marks give it away. I've got the source video anyway.

Dang, I must've missed it...

Ah yes... That.

I made a chart awhile back using a YouTube video, that had a thermometer attached to their weather balloon.

90,000 feet for altitude, and the type of camera is a lousy GoPro.

I'm not sure I understand the objection to the landmass.

Are you saying it somehow disproves the globe?

I may be able to prove otherwise if it somehow disproves the globe.

Spheres look weird when you put a camera extremely close to it.

I can demonstrate it if you want.

Although at the moment the best I got is Blender 3D and a large sphere.

I may do a better curvature gif if you have any suggestions.

Added fisheye lens for good measure, to simulate most weather balloon videos.

I can do a non fisheye version if you require it.

And that's perfectly okay.

I don't mind either way if the world is flat or round. I just happen to believe it's round.

So, I'm taking the time to better understand the document I was sent yesterday... I don't know if I should dispute the interpretation or not. I'm not really interested in converting anyone, I'm just hungry to be wrong about stuff that I'm convinced are true.

Anyway, when the camera goes high in altitude... I don't see explicitly where they say: "This makes the horizon curve." They mention Field Curvature, but that appears to be an entirely different thing.

I looked it up and tried to understand exactly what it is.

I get pictures of an image blurring around the corners when I look up examples.

I probably missed something.
