Swirling reflections on the Rochdale canal.

I took this one late afternoon in June last year. It's just outside Hebden Bridge, at the point where the canal passes under the road via the tunnel in the picture, then on to Mytholmroyd. The surface of the water had just been disturbed by around 20 ducks, all heading noisily towards Hebden.

Inside the Thames foot tunnel.

This was my favourite place to photograph on our trip to London in June this year. The tunnel runs from Greenwich across to Island Gardens on the Isle of Dogs - I had planned to walk through it after seeing the entrance steps on a previous visit. I had a feeling it might be fun to photograph and I was right. We walked through around tea time one day on our way back to our hotel in Greenwich, when the tunnel was quite busy with cyclists on their way home. I decided to return a couple of hours later in the hope of catching it empty and getting a different type of photo - this is one of them. (You also get quite different photos depending which section of the tunnel you photograph.)

Artificial lighting in Clink Street Tunnel on London's south bank.

If you search the internet for Clink Street Tunnel you'll find much more dramatic photos of the lighting under this tunnel (an old railway tunnel between Southwark Bridge and London Bridge). There is an installation of LED lights in the tunnel roof that is programmed to change according to the flow of pedestrians beneath it. When the flow is light, white LEDs twinkle like stars; when heavier there's a colourful firework-like display. It was the twinkling effect when we walked beneath it, but I chose in this photo to isolate one of the purple side-lights and the shape of the arch instead.
