Bokeh - Out Of Focus (DIY)

So, what is Bokeh? Bokeh in photography as defined by Wikipedia is the blur, or the aesthetic quality of the blur, in out-of-focus areas of an image, or "the way the lens renders out-of-focus points of light".

I created something similar to what is found in the Internet to create artistic bokeh or bokeh with different shapes aside from the common circular, pentagonal, octagonal shape of bokeh. By the way, I also read from the Internet that the bokeh is also affected by the number of aperture blades the camera lens has but I can't recall where I have read it exactly from.

Anyway, back to creating different bokeh shapes was something interesting and I tried it myself on my kit lens. Basically, it's like overriding the default bokeh shape of the lens. With the Christmas season, I took the chance to create and experiment on this one as there's a bountiful resource of light points from Christmas lights.

Here's my best photos:

Straight Curls

Circular Curls

Circular Triangles

 Here's my do-it-yourself interchangeable bokeh accessory that yielded the above photos:
