The second we open our eyes in the morning, we are using light to make sense of the world as we see it. In photography, light is essential to making a photo communicate to our viewers. the soft light upon a newborns face, the dramatic light of a soldier in the field, the early light of a sunrise through the forest canopy. The way we use this light will define our "photo story".
Ask yourself, what is it I want to capture, and what would be the best light to accomplish this. There are many resources today, that can give you insight into how light works in photography, and I suggest that you study some of these sources. (I have listed a few favorites below.) Even more important, open your eyes in a new way, to what light does. Look at the world and ask yourself questions like, what is causing that light, where is it coming from, what is the color of the light, how long will it last... and more. Become a "follower of light" and I guarantee that your photographs will start to take on a life of there own!
To get great photographs, you need great light.
