Method 1: The "DIY Bokeh Lens Filter"
This method is the most common and directly creates bokeh shapes.
What You'll Need:
* Black Cardboard or Thick Paper: (Free - recycle something you already have) The darker the better, so it doesn't reflect light.
* Scissors or Craft Knife: (Hopefully you already have this)
* Pencil or Pen: (Already have)
* Tape: (Masking, Duct, or Electrical tape will do - often already on hand)
* Camera (Phone or Digital Camera): You already have this.
* A Light Source in the Background: String lights (Christmas lights), city lights, fairy lights, or any small, bright points of light work best. *Note:* The further the light source from your subject, the better the bokeh effect.
Steps:
1. Measure Your Lens: Measure the outside diameter of your camera lens (or phone camera lens housing). This is crucial for sizing your filter.
2. Cut the Cardboard: Cut a circular piece of cardboard slightly larger than the lens diameter. You want enough overlap to tape it securely.
3. Cut the Center Hole: Cut a hole in the *center* of the cardboard circle. The hole should be significantly smaller than the lens diameter - about 1-2cm (0.4-0.8 inches) is a good starting point, depending on your lens size. Think of it as a mask, not a full opening. *The size of this hole will affect how much light enters the camera; smaller hole = less light.*
4. Create Your Bokeh Shape: In the *center* of the small hole you just cut, carefully cut out the shape you want to create your bokeh. Hearts, stars, diamonds, circles, and simple geometric shapes work best. *The size of the shape is important.* A shape that is too small will give a dim, indistinct bokeh. A shape that is too large will cause blurry areas in your photo that aren't aesthetically pleasing.
5. Attach the Filter: Securely tape the cardboard filter to the front of your lens. Make sure the hole is aligned with the center of the lens. Avoid getting tape on the lens itself.
6. Set Up Your Shot:
* Subject: Place your subject (person, pet, object) in front of the light source.
* Distance: Increase the distance between your subject and the background lights as much as possible. This will help create a shallower depth of field and more pronounced bokeh.
* Aperture: Use the widest aperture (lowest f-number) your camera allows. On a phone, this is usually automatic. On a DSLR or mirrorless camera, manually set your aperture.
* Focus: Focus carefully on your subject.
7. Take the Picture: Experiment with different distances between the subject and the background lights, and different angles. You may need to adjust the size of the bokeh shape cut out on your filter if the effect isn't what you'd like.
Tips for Method 1:
* Sharpness: The image might be slightly softer due to the filter. Editing in post-processing can help.
* Light: Make sure there's enough light. The filter reduces the amount of light entering the lens, so you might need to increase ISO or use a longer shutter speed (which can cause blur if the camera is shaky).
* Shape Size: Experiment with the size and shape of the cut-out. Smaller shapes will create smaller, more defined bokeh.
* Shape Placement: Accuracy matters. If you're cutting a star shape, try to ensure the points of the star are symmetric; an asymmetrically placed cutout will create an asymmetrical effect in your photo.
* Practice: This method takes practice to get right. Don't be discouraged if your first few attempts aren't perfect.
Method 2: The "Distance & Editing" Approach
This method relies on using distance, natural blur, and some light editing tricks. It's even cheaper because you don't need to make a filter.
What You'll Need:
* Camera (Phone or Digital Camera):
* A Light Source in the Background: Similar to Method 1.
* Photo Editing Software (Phone App or Computer): Free apps like Snapseed, VSCO, or Adobe Lightroom Mobile are great.
Steps:
1. Set Up Your Shot:
* Subject: Place your subject in front of the light source.
* Distance: Maximize the distance between your subject and the background lights.
* Aperture: Use the widest aperture (lowest f-number) your camera allows.
* Zoom: If using a phone, experiment with the zoom. Zooming in can help compress the background and enhance the blur.
* Focus: Focus carefully on your subject.
2. Take the Picture: Take several pictures from different angles and distances.
3. Edit Your Photo:
* Blur (Selective or Gaussian): Use the "blur" tool in your editing app to selectively blur the background lights. Gaussian blur is a common option. Some apps have "lens blur" modes that simulate the look of a shallow depth of field.
* Brightness/Contrast: Adjust the brightness and contrast of the background lights to make them pop.
* Highlight/Shadows: Adjust the highlights and shadows to emphasize the light and create a more dramatic look.
* Sharpening: Slightly sharpen your subject to make them stand out against the blurred background.
Tips for Method 2:
* Natural Blur First: Try to get as much natural blur as possible in-camera before relying on editing.
* Subtlety: Don't overdo the blur in editing. It should look natural, not artificial.
* Experiment: Play with the editing tools to find the best combination for your photo.
Why These Methods Work:
* Shallow Depth of Field: Bokeh is created by a shallow depth of field, meaning only a small portion of the image is in focus. Wider apertures and greater distance between the subject and background lights help achieve this.
* Out-of-Focus Highlights: The out-of-focus points of light in the background become the "bokeh."
* Light Diffraction: The DIY filter in Method 1 uses the cut-out shape to diffract (bend) the light as it passes through, creating the desired bokeh shape.
Important Considerations:
* Lens Quality: While these methods work, the quality of the bokeh will be different than what you'd get with a professional lens designed for it.
* Lighting Conditions: The best results are achieved in low-light conditions with distinct points of light in the background.
* Creativity: Experiment and have fun! The beauty of these methods is that they allow you to create unique and personalized bokeh effects.
* Phone Camera: If using a phone camera, look for phone apps that simulate the effect of a larger aperture (smaller f-number) which will cause more background blur.
Good luck creating your bokeh portraits! Remember that experimentation is key. Have fun and see what you can create!
