Awesome colorful bubble effect

Step 4

Go to Window>Brushes (F5). The first thing to do in the Brush Engine is to select our new Brush. The size won't matter because you will change that when you use it. The Spacing, however, is very important. Chage the value to 100%. After that, select the Shape Dynamics, then Scattering and Other dynamics. For the values use the image below.

Step 5

Before we start painting our bokehs let's create a new layer and fill it with a colorful gradient. I created a new layer and used the layer styles to do that but feel free to do the way you are used to. My gradient settings are as follows: Blend Mode is Overlay, Opacity is 100%, Style is Linear, and the Angle is 45º. The colors I used are: Yellow (#00085), Cyan (#1bdaeb), Purple (#9b3b81), Orange (#d27e34).

Step 6

Let's create a new Folder in our Layer Palette. Rename the folder to Bokehs and change the Blend Mode to Color Dodge. Then create a new layer, choose white for the color and select the Brush Tool (B). Now just paint some ellipses with our custom brush. For this first layer use a big size, like 500-600px.
