There is one thing the photograph must contain, the humanity of the moment. This kind of photography is realism. But realism is not enough - there has to be vision, and the two together can make a good photograph.
To me, photography is an art of observation. It's about finding something interesting in an ordinary place... I've found it has little to do with the things you see and everything to do with the way you see them.
Once the amateur's naive approach and humble willingness to learn fades away, the creative spirit of good photography dies with it. Every professional should remain always in his heart an amateur.
Light makes photography. Embrace light. Admire it. Love it. But above all, know light. Know it for all you are worth, and you will know the key to photography.
