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

Of course, the whole photographic process has been made much faster, cleaner and far more accessible to people by digital innovations, which is really great. Everybody now has a camera, often as part of our phone, and most of these cameras require little to no technical training. An enormous variety of apps also enable us to take short cuts to finished images. We hardly need to even think anymore.

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.

There is no one way of photographing anything. I don't believe there is even one best way of photographing any given subject.

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.

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.

There are many aspects about what and why we photograph: visual pleasure, personal empathy, intellectual stimulation, technical excellence, etc. Serious photographers and artists will try to create works that are original. Over a career period they may develop a singular identity in their images.
