How to Create a Fog Effect in Photoshop

Using Photoshop, you might want to create a fog effect. The way to do that is simple. Follow steps below.

1. Open a file that you want to create a fog effect. I'm going to use a image below.

2. Create a new layer in the Layers panel. Set Default Foreground and Background Colors in the toolbox. Fill background color(white) to Layer 1; a hot key is Ctrl + D.

3. With highlighting Layer 1, select the Filter drop-down menu < Render < Different Clouds.

4. Click "Add layer mask" icon on the bottom in the Layers panel, and Layer 1 will change like a image below. After then, select the Filter drop-down menu < Render < Clouds.

5. With highlighting Layer 1 in the Layers panel, set Opacity to 35%. You can see the image foggy like this below.

6. Select the Image drop-down menu < Adjustments < Brightness/Contrast. Set Brightness to -49 like a image below. After then, click OK.

7. Choose Screen to Layer 1 in the Layers panel, and then set Opacity to 35% like a image below. You can see the image changed. That's it.

You can compare before and after below.
