In photography, bokeh is the blur,[1][2] or the aesthetic quality of the blur,[3][4][5] in out-of-focus areas of an image, or "the way the lens renders out-of-focus points of light."[6] Differences in lens aberrations and aperture shape cause some lens designs to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting— "good" or "bad" bokeh, respectively.So, got it already? If you still don't, please proceed to the pictures below, and with the courtesy of Dwayne Foong*with my tiny bit of help*, he is going to further explaine how to get the BOKEH pictures..text from wikipedia
Instead of a boring round shaped lights, u might wanna try out something like love, star, clover and whatever it comes to mind.NOTE:The size of your cut-out will affect size of your custom bokeh- so play around with different shapes and sizes for all kinds of neat looks! :)

1. To begin, take a strip of paper and form a ring around your lens- (or u can measure your lens)
2. Trace a circle of your lens size, and later trace another bigger circle outside the initial circle. The bigger is to be cut like (picture below) to spport the cylinder.
3.Cut the circle, and roll paper to cylinder shape to fit lens circle.
4. Cut a square in the middle of the circle ( could just use scissors too. It doesn’t have to look pretty! :)
5. Now. cut your desire shape as shown above, you can cut a few in a square shape paper and stick it using a double side tape, so it's easier for you to change the shape while u're shooting.(I'm using my eye brow trimming scissor LOL because it's small so its easier to cut tiny shape =p)
6. Use your creativity, draw any shape you want, you can even try alphabets.. (Use a decorative punch if you have one, it will make your life so much easier.)
Final product will look something like this.. BTW, Dwayne called this" the custom made condom" for the lens. LOL
Sorry for my lousy description.. it's my first time doing tutorial like this, anyway.. i hope u get what i wanted to say XD.. starting for below are Dwayne's description =D
Hello guys,In order for this to work, it is recommended that you use a SLR (digital or otherwise), and a big aperture lens (i.e. 50mm f1.8).
You can also experiment with the bokeh size with the focusing ring. The custom bokeh will appear largest at the minimum focusing distance and gets smaller as you focus to infinity.
PS: It took a lot of effort for me to make the "condom", k? So please appreciate this, and comment pls is you guys wish to see more tutorial in future! =D


















The effects are beautiful!
