Different Perspective

These three pictures are of the same section of a footbridge across a river but taken from different angles and so they look like completely different things. The first picture looks as though it is upright rather than horizontal, it is smooth and shiny from the wear of many feet passing on it. The second shot although of the same section of the bridge is more angular and the texture changes as you look from left to right.  My favourite shot is the third one, I like the perspective and the way the focus changes the further into the image that you look.
