"Bokeh" is adapted from a Japanese word meaning "blur". In photography this term is used to describe the quality of the image areas that are not in focus.

Speaking of bokeh you can make out some features:

• The transition from light / dark is gradual or net?
• What form does a small point of light that is located in the Bokeh? (Mirror lenses, for instance, create a Bokeh donut-shaped).

We can play with these two variants to create special Bokeh. To do this you will need:

• A large focal lens aperture (in this case we used a Canon 50mm F1.8 but maybe a Nikon 50mm 1.8 or even better the excellent Nikon 50mm 1.4);
• A sheet of black construction paper;

Here's how:

1. Cut the cardboard to create a dummy plug for your goal. The diameter should be large enough to comfortably insert the cardboard target.
   
2. At the center of the cardboard cut out the desired shape of the bokeh, which in our example is a heart.
   I'm not sure how the crop should be great, but you can do a test using the viewfinder to check the effect.
   With a lens 50mm@F1.8 and a heart of 15mm in diameter, the depth of field is equal to F3.2, then probably you can zoom in (you can use a hand drill or cut).
3. Adjust the focal aperture of your camera to a minimum (fully open).

Here are two shots that show this technique - the first made with our cardboard pierced with the lens and the other "naked".

The parameters used in the photo above are:

• Lens: Canon 50mm F1.8
• Cardboard outer diameter: 70mm
• Diameter hole (center): 15mm

We propose below an interesting gallery created with this technique. Just try it for yourself and tell us your shots in the comments.

If you like the effect achieved, know that there exists a commercial version: The Bokeh Masters kit .
