My interest in light and time originates from a science background. Twenty years ago, I explored their interaction in Yorkshire seascapes, mastering long exposures to simplify a scene. When applied to cities, I discovered long exposures intensify the colours and minimise transient changes such as cloud and water movements, allowing the sole focus to be on the fixed lines of manmade structures. My aim is to capture that aesthetic balance of nature’s own lighting and artificial lighting during the narrow window at dawn or dusk.

The collection Equilibrium (two lights) is a series of photographs from eight cities across the globe that capture the delicate equilibrium of natural lighting and artificial light.
