You’ll be surprised how many Photoshop brushes there are for things you’ve always tried to create by hand. If you’ve ever tried to replicate a spooky forest scene, a gloomy London street, or even a smoke-filled concert stage, you probably tried using Photoshop’s air brush over a photograph to create some fog. No more. These fantastically realistic brush sets give you the foggy look without you having to constantly adjust opacity, size, and color to get it looking just right.
You will have to buy some of these ABR (Photoshop brush) files, while others are free to download and use under the Creative Commons license. Be sure to check the product specs on the download page, and then let your imagination drift free.
You shouldn’t. Unless you care about high-quality, convincing effects. Cloud brushes, fire brushes, and smoke brushes are just some of the custom-made pattern brushes developed to counter the inefficient and often time-consuming habits of digital painters and photo editors who try to do it by hand and get inconsistent (and maybe even unconvincing) effects.
These fog brushes in a pinch could work well for smoke as well as the flimsiest of clouds. The beauty of presets is that they often give you a range of options that you can replicate easily over many projects.
As ABR files, you use them as you would any Photoshop brush, recommended in a “dab” style instead of dragging the brush around the canvas.
Make sure to study pictures of actual foggy landscapes so you know where to put them and how much. Usually fog will be clustered and hanging suspended a few feet from the ground like a blanket. Mountaintop views will show them a bit like clouds. When in doubt, go easy on the use, or go heavy if you know what you’re doing.
These brushes are available in high resolution (2500 px and up) and come in different point shapes for different weather conditions. Anyone with Photoshop CS6 to CC should be able to use these without trouble. (Corel 16 users might be able to import ABR files as well.)
