A glimpse into the cabin of a Farne Islands tour boat.

This one's from August 2013, photographed on a trip out to the Farne Islands from Seahouses harbour.

Shadows and pedestrians crossing Southwark Bridge, London.

I'm always drawn to photograph this bridge when in London. In this image, from March last year, my main focus was the contrasting lines of the cranes, buildings and shadows, but I also really like the silhouetted pedestrians against the bridge wall.

Camera/lens settings: ISO 100, f/11, 1/80s, 32mm, hand held.

Shadows of trees across the path through Greenwich Park.

This London shot is from March 2015. It was a bright midday, hence the well-defined shadows.

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.

Canary Wharf tube station, London.

This one's from my recent trip to London. I love the shapes and light in London's stations - in this photo the light is pouring down into the station from the exit, silhouetting the commuters. Usually I don't like to have people in my photos, but here it works to give scale and motion to the scene.
