Creating Fog in Photoshop
by
Steve Bingham
In the real world of commercial photography fog is often a desired
element. That's why they make fog machines. In addition, some landscapes
can be enhanced by adding fog, overall or just in spots.
The biggest problem in creating fog is to create "depth
cuing". As we see further away the fog becomes denser. Here is a
very easy technique to master. (After clicking on the thumbnails, be
sure to expand the image.)
1_Open your image. Using the Layer Menu Box (Window, Show
Layer) create a duplicate layer. This preserves your original
and allows you to keep experimenting without losing any original
information.

2_ Now go to the bottom of the Tool Menu and select white as the
Foreground color.

3_ Use the Gradient Tool from the Tool
Menu. Choose
Foreground to transparent _ the second box which is shown when you
click on the Gradient down arrow on the top left of the page. Click on
something in the distance. Drag the tool from back to front to produce a
clear area in the foreground. Choose your degree of transparency. Use Normal
as your mixing choice on the duplicate layer. If the fog is not dense
enough, simply repeat the gradient. In this example it was done 3 times.
Flatten and there it is.
Save as a tiff or JPEG.



4_ For greater realism you can create a duplicate layer and use the
dodge and burn lesson to create darker and lighter areas in the fog
(patchy fog). The fog can then be swirled to simulate smoke. But that's
another lesson.
Again, this lesson has many other applications other than creating
fog. Experiment and have fun.
