Photography is all about being visually alert to the potential subjects that are present everywhere. And photography is also about asking questions concerning your subject and studying your subject so you can create an image that expresses it's true nature.
How much do we really see and comprehend once we have filtered the scene in front of us through our prejudices? I think most people would be surprised how much their environment in childhood formed strong structured perceptions of their world. I use to ignore details that I thought were not grandiose enough. I wanted the big dramatic landscape so I overlooked potential imagery right in front of me.
It takes time to be in tune to your surroundings and I am still working on being more perceptive in my choice of details and then composing those details in such away that gives the viewer a sense of the subject beyond any homegrown labels.
Macro photography is a good way to present a subject in such a way that creates mystery and gives the viewer a different perspective on a subject we might just take for granted and ignore.
