There are a lot of words used in English that are originally Japanese: Tsunami, karaoke, tycoon and bokeh. Bokeh is an effect that came from a happy accident. An out of focus lens captured the light of a candle which resulted in a blurred image with octagonal-shaped diamonds dots.
If bokeh sounds a bit hokey to you then Lumiè has dozens more high quality filters allowing you to mimic complicated photography techniques like dragging light, transparency or just adding random bedazzles to your pic! Normally $2.59, today Lumiè is FREE!
