in photography "bokeh" is the aesthetic quality of the blur. this technique is used to make the subject stand out.
i recently found a d.i.y. bokeh made out of construction paper on pinterest. as a photographer i found this project along with the newly found technique very intriguing. i have always seen this used in modern photography but i have never understood how to create the effect. i have learned that the right lens does a lot because the more aperture blades the better but i am still going to try this on my nikon standard lenses.
as you can tell i'm a beginner. i often like to fool around with my camera until i get the desired effect, however i will be doing further research on this technique. maybe i will post some of my own trials here soon!!! :)
