For years I have loved bokeh and wanted to try making my own filters like I see others doing. So I have been playing around and this is what I've got so far... I've only tried the star, snowflake and circle so far, will have to come up with some other shapes! And I am using a filter which kind of gives them a grainy feel, still trying to figure out the best way to do it!
For those of you who don't know what bokeh is, wikipedia describes it as - 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." For more info visit: http://en.wikipedia.org/wiki/Bokeh
