There are those times when a person is totally alone in some eerie landscape that seems a bit enchanted. When it really seems scary, it could be because your imagination is running wild. Local tales about a foggy forest attached to legends and claims that the woods are haunted might get you in the right mood.
And that is the right mood to take images in fog, mist or haze. This images can give a wonderfully moody and atmospheric feel to your subjects. However, it's also very easy to end up with photos that look washed-out and flat. You have to think a little bit ahead and use different techniques to make the most out of your unique shooting environment.
Photographing in the fog is a little bit different from the more familiar photography in clear weather. Scenes are obviously not as clear and defined, and they are often deprived of contrast and color saturation.
Fog is behaving like a big natural soft box. The light is scattered and is filling a much broader area. Compared to a streetlamp or light from the sun on a clear day, this dramatically reduces contrast.
The overall light condition in fog are as well much more dimmed — often they require longer exposure times than would otherwise be necessary. In addition, fog makes the air much more reflective to light, which tricks your camera's light meter into thinking that it needs to decrease the exposure. It is the same as photographing in snow.
In exchange for all of these potential problems, fog can be a powerful and valuable tool for emphasizing the depth, lighting, and shape of your subjects. Scenes can have a feel of mystery and an unique mood
In fog I like to emphasize the shape of subjects because it downplays their internal texture and contrast. The subject can even be reduced to nothing more than a simple silhouette.
Here some examples I took in Tam Dao some time ago.
