sunday school: 'tis the season to make bokeh


For photographers like me, if there's one thing we drool over during the holiday season, it's the seemingly infinite sources of itty bitty points of light EVERYWHERE, from one's own home, to the neighbor's bejeweled trees, to the local mall. And itty bitty points of light mean one thing to us, do they not? BOKEH BUBBLES.* That's right, folks. If the festive side of Christmas annoys you or stresses you out, look on the bright side--there are endless opportunities for blowing bokeh bubbles into your images.
If you've ever wondered how to capture the kind of magical bokeh characterized by dreamy floating balls of colored light, this is the perfect time to experiment and learn by trial-and-error. Just keep in mind these few basics, and you'll be an expert bokeh bubble blower in no time!
- Shaped bokeh is created by the blurring of highlights, such as small points of light or reflections of light. This is why sunlight poking through summer tree leaves makes for pretty bokeh.
- The shape of the bokeh is determined by the shape of your lens's aperture. If you like your bokeh nice and round, try shooting wide open with a fast prime lens like the popular 50mm f/1.8. If you want to get a hexagon shaped bokeh, try a narrower aperture such as f/4.5.
- The key is to position your lens with your subjects in the foreground with the points of light (such as Christmas tree lights) in the background so that when you focus on your main subjects, the lights behind them will blur into magical bubbles of bokeh.
- You can experiment with the size of your bokeh by changing the depth of field or focal length of your lens or by modifying the distance between your lens and the subjects and the distance between the subjects and the points of light behind them.
I've seen some great bokeh bubbles that make use of the abundant little lights of the holiday season. If you have images of such bokeh that you'd like to share, we'd love to see them. And if you have any tips on capturing the magic of bokeh, please do share those as well!
*By bokeh bubbles, I am referring to the shaped bokeh of blurred highlights, as opposed to creamy bokeh, which is just smooth blur.
