Creating your own Bokeh
You may have noticed an image called Bokeh in the Content or the Particle Emitter section of the Library. It creates a series of randomly blurred circles with bright highlights used to mimic a similar effect seen in photographs, usually on the background of the image. We're going to learn how we can create our own Bokeh from scratch.
Getting ready
Double-click the 07_10 project file from this chapter's exercise folder. The project consists of a group that has been turned off to act as the foreground of the project when we've done our Bokeh. Right now in the empty group, we're going to create a circle, add some filters, and throw it into a particle system. We will adjust the parameters and add some simulation behaviors to have it float offscreen left.
How to do it...
Select the Bokeh group and go to the toolbar to select the Circle tool underneath the Rectangle tool. Shift + drag your mouse in the Canvas to create a small circle on the screen. Press the Esc key to move...
