In this Instructable I'm going to show you how to make your own brush present using Adobe Photoshop CS3. Like many techniques in Adobe products, this can be accompished in near all versions, but the process might differ slightly.
First, we need a picture. I searched google and easily found a cloud picture that will work perfectly for this instructable.
Step 1: Selecting Unwanted Colors
Make a new layer for your cloud picture that you want to create a brush present for. This is crucial because we will be clearing out certain colors and need two layers to do this.
