The horizon is straight isn't it? But that makes the rest look slopey! Since actually editing photos (ie straightening) I've noticed that lots of things that I always imagined were level and straight are actually not at all!
I wish I knew what the girl was pointing to. I like to think it's a whale or pirates...or Norway
Ha! Don't we live on a round planet? Wouldn't that make everything sloped? We see it more in the water, like this. I always wonder how it would be living with my head pointing down. ;-)
you could choose to use the railings to get the straight line and make the horizon tilt slightly. It would have a different effect. I sometimes use correct camera distortion in photoshop to get the horizontal and verticals lined up
