Fog and mist are splendid elements for a landscape photographer. The most ordinary and familiar views can take a completely extraordinary look when photographed on a fogbound day. In my opinion the deeper the fog the better. Every time there's a foggy weather I try to go out and take some shots if I just have time. No need to go even very far, since all those sceneries you daily pass by look completele different and new in deep fog.
Fog turns landscapes soft, smooth, grey and simple. Simplicity and minimalism are maybe the most important things I try to achieve with the help of fog. All those ugly branches and shoots and dirty buildings etc. get engulfed by fog and it's much easier to get images that are concentrated around the main subject without all those disruptive details that you usually have to face when shooting out of studio. Fog and mist are also elements that add a lot to the mood of the scene. When the view becomes simple and minimal there's always the rising mystery of what is there behind that fog. Here's a couple of recent foggy shots. Both of these landscape shots are from very ordinary places that are full of distracting elements when the weather is clear.
Here fogbound however the scenes have lot's of mystery. The challenge in fog photography can be the soft contrast. Even in deep fog it's often eligible to get some parts of the view under better contrast. B&W conversion of the image can help a lot in this respect. In these shots I've also added artificial film grain over the images that in my opinion adds interest even in the smooth grey parts of the images.
