In Depth: What in the Heck is Bokeh?

What in the heck is bokeh?

What is bokeh and how is it pronounced?

Bokeh /bōˈkā/ is derived from the Japanese word “boke”, which means “blur” or “haze” [Wikipedia: Bokeh]

The dictionary definition of bokeh is the aesthetical visual quality of the blur or out-of-focus areas of a photographic image with a narrow depth of field or taken with a particular lens. The blur effect looks especially nice on lights and reflections. You’ve seen this effect hundreds of times before. I know you have.

Why do you want this depth of field effect? 

It looks beautiful and focuses your viewer’s attention on your subject.

In post-production, you can use a Lens Blur effect to simulate a bokeh effect. You can make it in your own eyes squinting your eyes, causing blurs through your eyelashes to all of the lights and reflections. This works best on a dark rainy night with lots of lights and reflections.

So, how do you pronounce it? It seems a bit like the GIF debate.

Some people are really annoyed by Apple’s pronunciation of the word bokeh and how they’ve turned it into a verb!

I really don’t care, personally. Pronounce it how you like it. I won’t correct you.

Let’s See a Few Examples of Bokeh

Below are some examples of bokeh on footage with lights and reflections.

 

How to Create Bokeh in Post

Boris Continuum BCC Fast Lens Blur

BCC Fast Lens Blur gives really lovely bokeh shapes effects. It’s easy to use and extremely fast, with 100% GPU accelerated replacement for their older version of the filter.

BCC Fast Lens Blur uses OpenCL to emulate a lens blur defocus/rack focus effect where out of focus highlights of an image clip take on the shape of the lens diaphragm. When a lens is used at its maximum aperture (fully open / set to the smallest f stop number) the out of focus highlights are typically in the shape of a circle, however, when the lens is stopped down (set to something other than the smallest f stop number) the blades inside the lens shape the out of focus highlights into multi-sided shapes. This filter includes a pop-up that can be used to match the different looks that can be achieved in the physical world based on the lens aperture setting. This pleasing optical result is referred to in photographic terms as Bokeh.
