If I had to give advice to other photographers, I would first suggest quickly getting over the camera equipment questions. In my humble opinion, the make and format of a camera is ultimately low on the priority scale when it comes to making pictures.

I do have strong convictions and political opinions, but I don't think it's necessary to imbue my photographic work with them. I use photography as a vessel for visual material to flow through, to encourage conversation with the viewer. I try to present a catalyst and invite viewers to tell their own stories.

It's possible to think of photography as an act of editing, a matter of where you put your rectangle pull it out or take it away. Sometimes people ask me about films, cameras and development times in order to find out how to do landscape photography. The first thing I do in landscape photography is go out there and talk to the land - form a relationship, ask permission, it's not about going out there like some paparazzi with a Leica and snapping a few pictures, before running off to print them.

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.

Essentially, I look for what is interesting to me, out there in the three-dimensional world, and translate or interpret so that it becomes visually pleasing in a two-dimensional photographic print. I search for subject matter with visual patterns, interesting abstractions and graphic compositions.

I would strongly encourage anybody embarking on photography as a career to embrace and enjoy the whole process. Being a photographer can be a wonderful way to experience the world.

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