A photograph is essentially light permanently captured on a medium. Photography is all about the way you capture light. The camera itself doesn’t recognize a cat from a dog, or a tree from a building. All the camera knows is the abundance or lack of light. Believe it or not, it is that simple for the camera. For the photographer, however, it is an unending battle.
Different photographers use different kinds of light sources. Some stick to strobes and controllable light sources (considered artificial light), others are more keen on the natural light, and there is the third class of photographers who will do anything possible to achieve the light they need (also known as available light).
The question now is: which lighting type is the best?
