haha. thanks @dek. i take photos of this pier all the time. after a while you start to notice a few things. top of my head, there could be two things in play. the pier is pretty old and is just not perfectly symmetrical. some of the pylons have moved/shifted. So you may see some larger or smaller gaps in between them. Also, i was using a 16mm wide angle. there could be some distortion from that also. i like the idea that it has a post apocalyptic feel to it. i am happy people are enjoying it. Thanks for taking the time and making such a great comment. see ya!
