Have you ever seen those photos with nifty bokeh shapes scattered in the background? Well, it’s actually easier to accomplish than you might think.
The shapes are a result of two things: bokeh and a mask (a mask for your lens, not your face). Bokeh is something that happens naturally with the right lens and lighting conditions, and the mask is something that you can purchase from one of our “local” photography bloggers.
Udi, from DIYPhotography.net, has put together the Bokeh Masters Kit so the rest of us can experiment with custom bokeh shapes. The kit includes a bunch of precut shapes and a holder that attaches to your lens so you can swap them out easily.
The concept is simple — place a thin mask with a small shape cut in the center right in front of your lens. The shape acts as a secondary aperture and forces the blurry background highlights to take the shape of the cutout. Without the mask, the shape of the bokeh takes on the shape of the lens aperture. But the mask cutout is just the right size to only have an effect on the bokeh while leaving the primary image in tact.
Right now, Udi is offering up three different kits: Demo, Advanced, and Master. The demo kit includes the disk holder and five pre-cut disk shapes. The advanced kit includes the demo kit plus an additional 15 disk shapes. And the master kit includes the advanced kit plus eight uncut disks and a disk wallet to keep all your disks in one place. The uncut disks allow you to create your own shapes and designs.
Now, you might be saying to yourself “I can make this stuff with construction paper, why would I buy it?” Well, because the disks and disk holder aren’t made of construction paper. They’re made from a thin and durable plastic and the pre-cut shapes are laser cut to give you nice smooth edges on your bokeh. Plus, the cutouts are just the right size to give your bokeh nice definition while minimizing any negative effects on the overall image. The blank disks in the master kit also have a circular guide on them to help you keep the size in that optimized range — I made myself a Christmas tree shape and took a shot of… the Christmas tree, duh.
[UPDATE 12/11/2009] Sorry, I just found out that the blanks no longer have the guides because some of the testers found that it got in the way of cutting. But you can trace your own outline from the circle in the disk holder.
I’ve known Udi for a few years now, and I was lucky enough to get a pre-production kit a few months ago. It was really neat to mess around with the kit and give some feedback to Udi (which he did take and work into the final product). So I’m pretty excited to see the end result of Udi’s hard work — he really has put a lot of effort into these kits. If you’re interested in the kit, visit the links below.
And if you guys have any cool bokeh shots (all shapes are welcome, even plain old circles or pentagons), feel free to drop them in the comments below!
