Those last two images are definitely left hand down a bit. It's a tiny amount, but it's visible when lined up with the top of my I pad screen.
My vernier caliper make it the same distance from top of image to horizon on both sides. I didn't enlarge it so it may be a pixel or two out but no more.
Aas one who used to take many seascapes with differing skies and encroachments on the horizon, I know how easily the eye can be confused. I lost count of the times I scrutinised horizons against a called up grid. I think the variation in the sky immediately above the sea horizon fools the eye into thinkinking it is not level.
My eyes see it as level, but I know what you mean about sky and headlands etc can confuse. I know I took the piss out of Craig’s iPad not being level (I hope he understood I was taking the mick) but it is slightly out using his method (something I do myself) but I think it’s that minuscule to even notice or frankly care about. Having said that if it had been pointed out to me I’d have to change it.
They are both 0.1 degree out I agree I obviously need to start wearing my glasses when adjusting the level in LR or PS I do not just rel;y on the level in my camera and I haven't adjust the current camera
I never fail to be amazed how nearly all my hand held shots are miles away from level, same as with a tripod, only not as exaggerated. I don't k ow how I ever managed before digital.
