This photograph is a crop from a photograph I took from a bateau-mouche cruising down the River Seine in Paris and is of the underside of a bridge. It seems to fulfil the ‘lines and angles’ requirement of  Cee’s challenge for this week.

It’s an interesting optical illusion that, although the image is a perfect rectangle the right vertical looks longer than the left.
