This is a photo that I took in Wales in March, on the Pembrokeshire coastal path.



The camera (actually a Samsung phone) was only about 20 - 30 metres above sea level when this was taken. But I wondered if I'd be able to see the curve of the horizon if I compressed the pic sideways, like this (image is cropped but shows the whole breadth of the first image):



Although it's tempting to blame the curvature present in the image on lens distortion, I don't think that's the case here. The horizon was actually slightly below the centre of the image, so any barrel distortion would tend to suppress the curve, not exaggerate it. However I have no idea how to do the maths for the degree of curvature you'd expect to see from that elevation. So I suspect that is just an exaggerated view of the Earth's curvature.

Anyone any thoughts?

I've edited my post as it did look a bit accusatory and patronising. Hopefully it reads better now.

Thanks but no need for that!  I've had far worse hurled at me on here

Ozempic anyone? Not only can you be skinny but you can prevent a heart attack. Uncanny coincidence, just as heart issues on the increase. What side-effects? 

In three of the four quarters of 2023, the Danish company delivered the sharpest revenue increase among biopharma's top 25 companies ranked by market capitalization. For the full year, Novo delivered a 31% increase in sales, reaching 232 billion Danish kroner ($33.7 billion).
