When I think I have found a scene to photograph, I like to stop and take a second or two to observe what is going on before taking an image. I am looking for something magical; it may be a special light, or just something that really captures the mood and the atmosphere of the city at that particular time. The key, though, is stopping to look before shooting.
DON'T SHOOT THE OBVIOUS
The most important thing for me is to try and reproduce the atmosphere, the energy, the DNA of a city. It is easy to shoot a picture-postcard image of a city like New York. You may get a good picture as a result, but we will have all seen such an image 1,000 times before. Instead, look for interesting compositions or colours to try and make your picture's original - add something of your own to each image.
