Just a quick tutorial for any of you,like me , who’ve avoided creating their own brushes in Photoshop. I’ve chosen a ‘fog’ brush using a cloud image as a base. It could of course be used for anything else like smog,smoke,mist ..really any number of uses. The process would be the same if you wanted to create a brush using any base. 

I use a Windows PC so instructions are generic for that but I believe Command can be interposed with Control if you’re on a Mac. Enjoy, comment and subscribe to my You Tube as I’m sure there’ll be more delights coming your way.
