I don't have anything against colour. It is just not my first preference. I have always found black and white photographs to be quieter and more mysterious than those made in colour.

Everybody now has a camera, whether it is a professional instrument or just part of a phone. Landscape photography is a pastime enjoyed by more and more. Getting it right is not an issue. It is difficult to make a mistake with the sophisticated technology we now have. Making a personal and creative image is a far greater challenge.

I encourage playfulness and experimentation with both the camera and subject matter. Sometimes there is an obvious perspective, but it is important never to be satisfied with that.

Perhaps most intriguing of all is that it is possible to photograph what is impossible for the human eye to see - cumulative time.

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.

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.

I believe that every photographer, every artist, should choose materials and equipment based on their own vision. I don't believe that non-digital is necessarily better than digital, or the reverse for that matter. They are just different, and it is my preference and choice to remain with the traditional silver process, at least for the time being.
