This are two different type of bubble brushes: soap bubble and water bubble. I created them in Photoshop CS3 Extended.
If you use, please don't commercially redistribute or claim as your own. You can
use them in prints. And you are allowed
to post work using them in or outside DA. You don't have to ask me for permission.
Credit me if possible and link me back to your work. I'd like to see what you did with them.
