Its not really subtle zoom in and you can see it with a ruler. I suspect what you may have there is barrel distortion.

Kk, well i guess i stand corrected, however could it not also just as easily be the curvature?

Why does this distortion always have the edges down and the center up? That's like no optical distortion that I've ever heard of.

Sorry? Maybe im missing something. I though barrel distortion caused the centre of an image to bulge away from the centre line. So I think that if that horizon was below the midline it would make the Earth look concave. Maybe ive got it the wrong way round in which case I think its called pincushion. It could be a real effect I guess but i'd be suprised.

Im sorry, im new to posting on forums, so i could (and have) put a straight line on it, however i am clueless as how to re-upload the edited picture.

You have to host it with tinypic or a similar site.

I prefer photobucket.

Anyway there is a curve.  However, because the horizon is fuzzy, the curve is only about 5 pixels from center to end.  It's visible but difficult to define.

Look up barrel distortion.

You really can't see the curvature of the earth at ground level. There is quite good paper about that - Visually discerning the curvature of the Earth

Well, here's a diagram from the wikipedia page on distortion that may illuminate things for you:

http://en.wikipedia.org/wiki/File:Barrel_distortion.svg

Note that toward the top of the image, where the supposed curvature in the photograph is taking place, the edges are level and the arc peaks in the middle of the diagram.

Good thing we never said anything about the center being distorted. Where the "curvature" is, is not the center.

I understand the point. So the hypothesis is not just that there's a barrel distortion, but also that the horizon is very near the top of the original photo.

Could you reitterate this? I'm not sure what you are saying...
At first you say that there is barrel distortion,

and then you say that there isn't any?

but only that it horizon is very near the top of the original photo.

I'm confused.  :P

Yes and no. There is barrel distortion, but that doesn't mean something has to be near the edge for it to be distorted. Anything that is not the center is going to have distortion.

Best way to see that the curvature is to actually look at the waves.
According to FE, you should see the waves in the far off distance get smaller and smaller (blurrier and blurrier)until they vanish.  The reality, however, is that they don't.  You see waves up to a point with a fair bit of clarity then they abruptly stop.  You know, in your mind, there are more waves across the Ocean but you can't see them even though you should be able to.

With the barrel distortion argument, if the picture were taken facing even slightly above the horizon, it would curve in the opposite direction, which is precisely why pongo's window lensing fails (though it is only one reason of many).  I guess people somehow missed this post:

Good thing where the "horizon" is, is in the top portion of the picture, so it's bending agrees with barrel distortion.

Btw, you should fix that picture, you can barely even understand what you are talking about the writing is so sloppy.

The picture wasn't taken slightly above the "horizon". The "horizon" is easily above the center of the picture, so the way it bends is true to barrel distortion.

So you are saying the picture has been doctored?

i believe earth is round, but if you go far enough there is a point where the circumcision is present, and there is where you will find the point of contact of the water.

I think that your circumcision should have gone further.  For the sake of the gene pool that is.

It seems to me the options here are either barrel distortion or that the picture has been doctored.

Good argument. However, the reason the Earth looks curved from a high altitude is actually because it is spherical.

Awesome argument. You made so many great points there.

This single post gave more insight to the world as we know it than everything else in this thread combined.
