The horizon does slope here. I did think of straightening it as I sometimes do in such instances - but then I realised that the leaning tree would end up at a very strange angle!
I was over the fields, Knowle Park, just me and my camera.
How very well disciplined of you, Hazel, to keep your eye on the horizon and resist the temptation to correct it. Well done! People could have fallen off and might never have been seen again. Flat Earth, indeed!
The sun was right behind that tree. Thank you for the reassurance.
Oh,and thanks for your lovely comments on mine.
Arthur you made me smile, first thing in the morning!
