When a shot of a distant scene is hazy, foggy, or smokey, this can be a bad thing. Low contrast can destroy that ice image of the distant scene.

But you can also make it into a benefit. By putting sharp objects large in the foreground. Now the haze helps to accentuate and apparently sharpen the close object.

So now the disadvantage becomes an advantage.

So whether it is a fire you are photographing, or the Grand Canyon, or London: try to get a sharp object large in the foreground if the background is hazy.
