The next step is understanding how to capture it. Fog is often difficult to capture on camera. Subjects are no longer clearly defined, as the fog deprives the camera of clear light, contrast and colour.
In essence, fog scatters light so that it covers a much broader area. This makes it difficult to capture your subject as there is no clearly defined source of light. The lack of light can also be an issue. The early evening or morning will mean there’s less light available, which often means you have to extend your shutter speed to allow more light in.
Additionally, the fog will make air much more reflective, which can trick your camera’s light metering into thinking the shot is over-exposed, so you’ll need to manually adjust your exposure to compensate for this issue. While it may seem like a pain, fog and mist can lead to some truly beautiful compositions that are unique and moody. The trick is trying to find a balance between this ambience and your subject.
