This photo appeared on my computer's desktop yesterday.
I snapped a photo of it because if illustrates the truth of flat earth and the law of perspective in a single photo.

You see the flat horizon with no curvature.
You see the flat plane scrolling away from you at eye level.
You see the convergence of two parallel lines to a single point.
What a nice picture!
Too bad it only shows about a half mile of depth of field!
These old pier stumps only go out a few hundred feet at most.
You need several miles' distance to see the earth's curvature.
While this nice picture is nice to look at,
if you're trying to demonstrate the reality of the earth's shape,
you need to use a lot more depth of field, obviously.
Here you can see the beginning of the earth's curvature in the distance.
Your photo, above, only covers about the first 5 of these towers.
The first 10 of them appear to be in a straight line.
Only after 20 or more do you see the curvature beginning.
It takes a great distance to see this curvature because it is very subtle.
You need several miles' depth of field for starters.
