Sometimes you strike it rich, but you don’t know it at the time.
This photo is a case in point. As I was taking this photo, someone stepped into frame and looked at the camera. I remember being annoyed at the time. It wasn’t until I got it back on my computer that I realised it actually improved the photo. I went from a simple pic, to a photo with layers.
The seagulls eating the scraps on the ground, the random who walked into the image just as I pressed the shutter (it works) and then the plain shed but cool billboard on it. Oh and the flags.
