Recently I was asked by a client how to make a highlight star burst in Photoshop. It’s rather easy to do if you can create the image in the first place. I volunteered my services to create the image and sent it to her with these instructions:
1. Using any selection tool, select the image you want to use as a custom brush or copy over the individual image to a new file. Don’t make it larger than 2500 pixels square.
2. Choose Edit > Define Brush Preset.
3. Name the brush, and click OK.
Pretty simple, you can either use the sample I posted here or have fun and experiment with creating your own Brush Tip.
