1. Reasonable control of exposure. In the fog, the whole world is white. The camera's automatic metering system is easily disturbed by the environment. Shooting fog, exposure accuracy is a critical issue, the fog scene of the picture is generally mainly light gray and white tones, only a small amount of content is darker tones, so the exposure of the fog scene should be shot according to the shooting of the specific circumstances of the moderate increase or decrease, usually 0.5-1EV value is more appropriate, and sometimes if you are in accordance with the normal metering tends to underexposure of the situation. If you need to deal with the picture into a high-profile effect, you can increase the exposure compensation of 1-2EV, but pay attention not to let the highlights of the storm, this technique is suitable for expressing the mood of light and soft; if you reduce the exposure compensation, it is suitable to express the effect of heavy and deep, according to the needs and settings.

2, seize the light at a favorable time. Dense fog will cover all the colors, shades and shapes, and the photos are easily gray. When shooting, you need to look for light that can pierce the fog and add drama to the picture. Early morning sunlight and evening streetlights are excellent subjects. Night shots in fog are also often very effective, especially when the sky is not yet completely dark and the sky is just starting to darken.

3, recognize the significance of white space in fog photography. Photography in many occasions need to do a reasonable subtraction, and the use of white technology is one of the specific embodiment of subtraction, which is particularly obvious in the fog scene shooting. White space, that is, in addition to the visible physical objects on the photographic screen outside of some of the blank parts, they are composed of a single tone of the background, the formation of physical objects between the gap. Single-tone background can be fog, sky, water, grassland, land or other scenery, due to the use of a variety of photographic means of reason, they have lost the original physical object, and the formation of a single tone on the screen to set off other physical objects.
