1. Create the Design
First you need to create your design. Start by cutting a circle the size of your lens out of black construction paper. You can start by tracing your lens cap.
Now, cut out your circle as well as cutting out a small design in the middle. It can be any shape you like, such as a heart, star, tree - anything! Your kids will love coming up with different ideas.
Next, carefully place the paper onto your lens, making sure it is secure from any light leaks. I left a tab on my circle so that it is easy to remove, but you can also tape it down.
Now you are ready to shoot! Lets get into the shooting settings.
2. Choose a Low Aperture
First you need to begin with a low aperture to get a bokeh affect, begin with around 1.8. I suggest shooting with a prime lens, such as a 50mm.
3. Shutter Speed and ISO
You will need a slow shutter speed and high ISO as you are limiting the amount of light getting into your lens, and your room will probably be fairly dark. You can also shoot on aperture priority mode.
4. Distance from Subject
If you would like shapes to appear behind a subject, make sure there is enough distance between them and the tree.
My settings for this image were F/1.8, 1/125, ISO 6400 with a 50mm on a Nikon D750. There will be a natural vignette effect to your images, so don't worry about that.
5. Manually Focus
If you do not want a subject in your photo and just the tree, the lights will have to be out of focus. Purposely manually focus your shot so that it is out of focus and your shot will end up like this.
