Here is an unaltered picture of my nephewâs fence in Newalla, Oklahoma. Took the picture with my Nikon p900. The fence is actually perfectly straight. Why the distortion?
The distortion is because of the hill, an optical illusion I suppose.
The hill and forshortening, when you move from 3-d to 2-d.
Interesting! Try a 3D shot of it, an Anaglyph perhaps, which can be seen by us with red and cyan glasses and we'll see how it reads in 3D.
You are at an angle to the fence, not looking straight down it and it goes up and down over the ground so you get this optical illusion that it is curved in the horizontal as well as the vertical.
Your (and my) mind is "re-arranging" it because of the terrain and the perspective angle.
Looks like you used a telephoto lens as well.

Used my nikon d900 and it was zoomed in.

I'm 80 years old, I think my mind re-arranges a lot of things😁
Thanks, the telephoto exaggerated it, but it looks the same with the naked eye.
I like the fence as it is seen in the photo
Would seem the rise of the hill it covers distorts the straight line. I'm sure a physics person has a more technical answer
