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.

Disused mill on a cobbled lane in Halifax

I took this in April on a walk up around Southowram from Halifax centre - this mill is at the foot of the hill in Siddal. I like our old mills (particularly the disused ones) - both their structures and their history.

Steep cobbled path between trees and fallen leaves

This path is on the hillside opposite Jerusalem Farm, at Booth. I took the photo on a walk around the Luddenden valley in February this year. The path was a useful short-cut, rather than following the winding road all the way down the hill, but turned out to be dangerously slippy in the wet weather. I made it to the bottom with only a couple of slips though (and, importantly, my camera intact!).

Cobbled lane in the Luddenden valley

This cobbled lane runs down from the road between Luddenden and Booth; the hillside in the background is below Wainstalls. I took the photo on a walk around the valley in February this year. The original raw file was very contrasty - bright sunlight and dark shadows. Converting to black and white enabled me to better balance the light in different areas without confusing any colours.

1800's textiles mill and chimney on a cobbled lane in Halifax

Today I had to leave my car at the garage in Halifax to have some work done, so I decided to spend the morning walking around town with my camera (for 'locals' the route was up Beacon Hill Rd to Southowram, over the top and down behind Siddal, past the Shears pub, then back behind the Nestle factory to the town centre again).

This photo is looking up Boys Lane at Shaw Lodge Mill and its chimney. They were built in the 1800's for woollen/worsted textile weaving by John Holdsworth & Co and remained in their ownership until 2005. (I think they're rented out as separate units now).
