In my case it can be a very undisciplined individual. When I leave home with the camera anything can become my unsuspecting subject.I seldom if ever have an agenda I just keep exploring my surroundings and looking for angles and lighting that will make appealing and hopefully insightful pictures. I think what may separate photographers from others is not the equipment hanging around the neck but how he/she may see things. A different perspective, stunning or subdued lighting, a beautiful person, face or place. Also you look for potential for post picture manipulation to emphasise what has been envisaged when the shutter is released. It's been said that photography is a window to life. For me thats so true.
There is nothing I am not interested in when I am out and about. Revisiting places many times to catch subjects in a new light.
What's behind the camera? Well an old guy with a keen interest in life and all that comes with it. Bring it on........
One famous New York street photographer was once asked "are you frustrated when you are changing film and miss a great photo?" he said something like "there are no photos when I don't have film in my camera"
Now things have changed and one thing digital technology has given us is capacity. It is possible to take thousands of shots on one storage card. I simply love digital photography it's opened up opportunity for creativity (in some cases too much). However in the haze of current technology advancements and all the nice toys that are available if the $$ can be found one should not forget the one thing that photographers for generations have appreciated, light! Simply explained light, lighting angle, lighting balance, intensity are what make an average picture a good or even great image to be appreciated. The old masters knew and understood the value of light. I am still learning after 35 years of photography. Long may it continue.
