Bokeh effect is nothing but the blurred part of the out-of-focus image. This effect is normally seen in the photography mostly around the light sources. In photography, this effect helps to focus on the object while making the background visually appealing. Today we are going to learn how to create the same beautiful effect in Photoshop. Before starting the tutorial let’s take a look at what we are creating.

Creating the Brush

Step 1: Open Photoshop and create new file

For creating the Bokeh effect, first we have to create a Bokeh Brush. So start with this.
Open Photoshop and create new file (File>New) with following details.

Step 2: Setting up the Brush

Now select the Elliptical Marque Tool (M) and draw a circle (Press Shift and Draw) to fit in the canvas. Go to Edit>Stroke and add the centered stroke of black with 5px. It will look like this.

Create a new layer (Shift + Ctrl + N) and (if you have deselected) (Ctrl + Click) the small thumbnail in the layers panel of the previous layer. Fill this new layer with black and change its opacity to 30%. Press (Ctrl + E) to merge the layers.

Step 3: Saving your new brush

Okay, we have created the brush. Now go to Edit>Define Brush Preset and give a name to your brush like Bokeh Effect and save it. You can now see the newly created brush in your Brush Panel (Windows>Brushes or F5).
