Bokeh is the blurred effect you see in a photo when things are out-of-focus. In certain cases where the out-of-focus area contains a lot of light and different colors, the blurriness can create an interesting aesthetic that is pretty to look at. Bokeh has made its way from photos to the digital space as made evident by an abundance of bokeh-inspired wallpapers available for desktops and mobile phones. Here are some examples of bokeh in photography: Example 1, Example 2, Example 3, Example 4, Example 5.
The goal of this tutorial is to create an abstract bokeh-inspired wallpaper like the one displayed above.
