Bokeh ("blur" in Japanese) is an effect that came from a happy accident! A lens out of focus captured the light of a candle which resulted in a blurred image with octagonal-shaped diamonds dots. The light painting in Lumiè also inspires. The city lights and all night movement of these places will be part of your images. 27 effects in various formats
