Nicely done Sporgon...sometimes the horizon can be tricky can't it?
Thanks Northstar. Yes it can, in fact I have an alarming inability to hold the camera level. I think it's probably because I tend to look through the camera with my head tilted to one side. I normally have to rotate my images anti clockwise, and it's surprising just how much image area you loose if you have to rotate even 1 degree.
I almost never have a level horizon. Usually always off about 1 degree (usually must rotate counterclockwise to correct). I have pondered this and some thoughts:
1) my head or eyes or brain is tilted
2) I rotate the camera slightly when I press the shutter
3) maybe the sensor is rotated slightly in relation to the viewfinder
4) you just can't consistently be perfect
