You do if you want to claim this photo supports a flat earth

You've already forgotten what we were talking about? That's a little sad :(

No one claimed any photo you shared supports a flat earth. Perhaps you need to go back and re-read in order to remember what we were talking about.

Especially after spending an entire day telling me how invalid this photo is as evidence due to distortion

I appreciate that is all you experienced / can remember - but i never said anything of the sort. I never said the photos you shared were invalid, and it didn't take me more than a single comment (a sentence or two, actually) to explain why the photos do not and cannot show the curvature of the earth. The "entire day", continuing into today - has only been to try and help you to understand those few sentences.

Also, you need to measure the distortion too, not just the distance in the photo.

Again, i'm not the one who is confused about the globe model or the extremely subtle (essentially imperceptible) curvature that is described in it and would be (by calculation) visible on such scales.

If the reason for the ostensible curvature is not due to distortion, which i agree is the presumptive/deductive cause, then what on earth do you think causes it? Do you truly believe the world is far tinier than the globe model describes / we're taught? I am having difficulty imagining another option.

I'm not wasting my time on any more novels from you

They are only a waste if you don't read and/or understand them. When you don't understand, the best thing to begin with is to ask questions!
