Fog has always provided a sense of mystery and unknown. In photography, it can be used to enhance or hide details. I love shooting in fog just for this reason. In central Pennsylvania there are plenty of vistas and sites that would make a high quality composition. But I rarely have the time to plan out capture that requires me to sit for hours in preperation. Between a job and family, I’m lucky to make it three blocks from the house without my dog on leash. So foggy mornings are highly valued as a way to convert a boring scene into something interesting.
Below are three shots taken on my iPod. All three shots are of a local high school soccer field framed by tree branches and another row of maple trees in the distance. And all were taken from roughly the same perspective, at least viewing through the same trees.
The top photo was shot in a frozen fog. The world is black, white and a color drained green. The foreground tree branches provide a nice contrast to the white fog. In the distance a row of maples line a road that is currently obscured. A couple of cars are visible as is the infield of the baseball diamond. Without knowing the landscape, this is a romantic field lined with trees that fades into the distance. A little more post work could remove the cars and even up the imperfections. But in general, I really like this shot. An instagram version is found here.
The next day was a typical December morning. All of the components from the fog shot are there, the framing branches, the trees and field. Even the sky is similar, a dull white cloud cover but dominates the image. But without the fog, the field looks worn, the baseball field is a smear, the roads slicing through the right side, and the school is injected on the left. Its a dreary, somewhat depressing, and eminently forgettable image.
So what about a bright sunny day and blue sky? Sure, its better than the gloomy day above, but its still rather stark. The blue sky is a great improvement over the clouds. While there are virtues of shooting on cloudy day, those images tend not to capture the clouds as a prominent component, but use the soft diffuse light to evenly light an object or face. This bright blue sky puts the field, road, trees, and school in a more positive winter mood.
In short, fog adds mystery and romance to an image. Its ability to mask details as a gradient means that by moving to compose the shot, undesirable components can be hidden.
