We see in colour all the time. Everything around us is in colour. Black and white is therefore immediately an interpretation of the world, rather than a copy.

Different assignments, different places, require different approaches. Sometimes I take minutes in a location, at other times days. There are many places that I have returned to over several years. When I photograph, I look for some sort of resonance, connection, spark of recognition.

For me, the subtlety of black and white inspires the imagination of the individual viewer to complete the picture in the mind's eye. It doesn't attempt to compete with the outside world. I believe it is calmer and gentler than colour, and persists longer in our visual memory.

Craft is important, but cameras for their own sake are not. A sense of aesthetics, a connection with the subject matter, an enquiring and an inquisitive mind, these factors outweigh whatever equipment we use.

The first time, I usually skim off the outer layer and end up with photographs that are fairly obvious. The second time, I have to look a little deeper. The images get more interesting. The third time it is even more challenging and on each subsequent occasion, the images should get stronger, but it takes more effort to get them.

My advice to any budding artist is never to be satisfied with imitating others. This is but a means to an end. A serious artist will work with intensity to discover themselves, their own personal vision. I believe this is a fundamental aspect of the creative path.

Getting photographs is not the most important thing. For me it's the act of photographing. It's enlightening, therapeutic and satisfying, because the very process forces me to connect with the world. When you make four-hour exposures in the middle of the night, you inevitably slow down and begin to observe and appreciate more what's going on around you. In our fast-paced, modern world, it's a luxury to be able to watch the stars move across the sky.
