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.

If the quality of professional materials continues to erode or even dries up, then many of us silver photographers would have to follow the digital tidal wave. It certainly wouldn't be the end of the world, but in my opinion, having no silver material available would be a huge loss to photography.

Easier is not necessarily better.

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.

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.

Instant gratification in photography is not something that I need or desire. I find that the long, slow journey to the final print captivates me far more.

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.
