What You'll Be Creating

‘Tis the season and with all of those holiday lights around, who can resist a little bit of festive bokeh? In this tutorial I’ll show you how to create something a little bit different to get a new twist from those tree lights!

What You’ll Need

What you'll need for this tutorial
  • Tape
  • A pencil
  • A sharp craft knife
  • Scissors
  • Thin black card
  • A low-light lens (a lens with a large maximum aperture)
  • A surface to cut on (I recommend a chopping board)

1. Make a Lens Hood

The first thing you need to do is cut part of your card into a strip wide enough to fit around your lens:

Cut the card into a strip

You'll have something like this:

Strip of card for around your lens

2. Make Your Template

Next, draw around your lens with the outer glass (where the lens cap is) face down:

You don’t need to be neat about this part. Once you have your circle, draw another circle about an inch out like this:

You should have two rough circles

Cut out the larger circle then cut out little triangles from the outside, to your inner circle without cutting into the inner circle like so:

cut triangles into outer circlecut triangles into outer circlecut triangles into outer circle
Cut triangle shapes into the outer circle

Do five or six of these until you can bend the outer parts like this:

Fold the outer circle in

 We’re going to use this to bend around the strip we made before.

3. Cut Out Your Custom Shape

Draw your custom shape in the middle of your circle. Keep it quite small, a large one won’t work very well. For ease of demonstration I’ve chosen a small Christmas tree. You do need to be quite neat about this part as it’ll show up on your bokeh if you have any rough edges. Once you’ve drawn your shape, cut around it carefully with the craft knife. Remember to use your cutting surface, I don’t want the blame for any holes in carpets!

4. Make Your Attachment

Take the strip of card you cut out earlier and wrap it around your lens:

Wrap your strip of card around your lens

Tape it to itself to form a snug fitting (but easily removable) tube. Next, take your custom bokeh card and tape it to your tube, covering any gaps with tape.

You should now have something that fits to your lens but comes off easily to look like this:

Your finished attachment should look something like this (or neater!)

The size of your ‘tube’ does matter, so you may want to trim it down after you’ve tried it out.


The technical stuff

It’s not easy to get great results in Auto as you’ll confuse your light meter massively so you may need to flip to Manual mode, or at the very least Aperture mode. Choose your lowest aperture, a fast(ish) shutter speed and remember to manual focus.


This is a fun method of creating some really abstract bokeh shots. Here’s what my Christmas tree looked like with the custom filter attached:

This works with any points of light so try it with candles or get some battery powered fairy lights for custom bokeh on the move!
