Swirly Bokeh

Searching, studying, and experimenting on how “Swirly Bokeh” (aka Cat’s Eye Effect)  form, it’s been two days and now I can conclude what I’ve found.

Definition:

Swirly Bokeh (Cat’s eye effect); because the Bokeh is making a circular shape.

How Does it Form?

I will list the “recipe” as points, so you can understand easily (of I what I’ve read, and experienced):

  • You need Bokeh in the background, so that you’ll be able to see the “Swirl” effect (e.g. Keyboard, Grass, Bokeh of light coming between the leaves)
  • If the background is plain, lined, or lacks Bokeh then you’ll never have it (e.g. background is PC Screen, Walls)
  • Stick to focus range between 0.6 to 1 (if you go 0.5 or more than 1 you’ll hardly see it; you don’t get so close, and you don’t keep a big distance)
