DIY Cartboard Pattern - Create Your Own Bokeh Effect in Photography and Video

DIY - Bokeh effect
ISO 100, 50mm, f/1,8, 2.0sec 

The bokeh is the blur, or the aesthetic quality of the blur in out of focus areas of an image.

This time I will show you how to transform the out of focus lights into a shape.

What you will need:
  • pen or a pair of compasses
  • sheet of black cardboard
  • scissors
  • cutter or sharp knife
  • lens with a large aperture (f /1.2, f/1.4, f/1.8) or a zoom lens

 DIY - what you need for bokeh effect
I will use a Canon 50 mm, f/ 1.8.

Now you need to cut the cardboard to the lens diameter.
Yow can use the lens for marking or just a pair of compasses.

Out of focus lights will take the the shape of your cardboard pattern (decoupage).

As you defocus the lights in the image the shapes grow bigger.

You can make many forms from harts, stars, smiley faces... Use your imagination and create art from anything.

I want to show you just how you can focus on a closer object or person and in out of focus yow will have the bokeh shape effect.

Whit the zoom lens is the same thing:  yow take the shot whit large aperture and focus somewhere close to the lens and the lights will be out of focus. They will appear  in the shape of your pattern.

Yow can use this effect to make a movie too:


That`s it. Hope you'll have fun.

Drop me questions if you have any.
