The Foggy Days of Autumn

It's been foggy in the Puget Sound area lately. And I love fog combined with autumn color. The cool moist air makes hiking in the woods pleasurable. But are there images to be made in the fog? Of course there are, lots of images.

Fog is like a giant soft box and reduces contrast you would see on a bright sunny day. Which makes a foggy day perfect for photographing images that are better on overcast days; forests, flowers, faces and waterfalls or the 4 F's.

Why does this happen? Fog acts like a giant softbox. Fog disperses light (bounces and filters) reducing hard shadows. But these qualities can also fool your light meter into under-exposing your images - over-expose as you want that bright glowing light.

This diffraction of light helps to emphasize the distance between near and far objects. The image above is an example of this. The closer tree is well defined yet as your eyes move further into the background, the trees become less distinct until they become barely visible shadows of themselves.

On an ordinary day, this scene would be a jumble of trees and shrubs, making it difficult to isolate one tree from the rest. In the fog, the shape of the foreground tree stands out. You know that this is a field of trees because of the subtle shapes behind the front tree. But the limbs do not get lost in the limbs of the other trees - they are isolated and defined.

There are no harsh shadows falling across the field. Harsh shadows combined with bright sun on a bright day would be even more difficult to capture an image of these trees. Your light meter would either want to expose for the bright areas or the dark. You can overcome this harsh environment with multiple exposures and combining the images in Photoshop. Or you can wait for a foggy day.

Photographing in the fog both challenging and fun. So the next time you wake up to a foggy day, grab your camera and have some fun.
