DIY: How to Build and Use a Reflector for Better Portraits
Reflectors are essential tools for photographers, especially portrait photographers. They bounce existing light (like sunlight or artificial light) to fill in shadows, even out skin tones, and add a catchlight to the eyes, resulting in more professional and flattering portraits. Buying a reflector can be an expense, but you can easily build one yourself with readily available materials. This guide will cover building a basic reflector and how to use it effectively.
Part 1: Building Your DIY Reflector
Here's a simple and cost-effective method for creating a versatile reflector.
Materials You'll Need:
* Foam Core Board: This is a lightweight, rigid board commonly available at art supply stores or craft stores. Choose a white or silver board for maximum reflectivity. You can also get black foam core for a negative fill. A 20x30 inch (50x75 cm) board is a good starting size.
* Aluminum Foil (Optional): This can be glued to the foam core for a brighter, more specular (direct) reflection.
* Fabric (Optional): White, silver, gold, or black fabric can be stretched and glued to the foam core for different reflection effects. Think old sheets, t-shirts, or upholstery fabric.
* Spray Adhesive (Optional): For attaching foil or fabric to the foam core.
* Scissors or Utility Knife: For cutting the foam core (if needed).
* Masking Tape or Duct Tape (Optional): For reinforcing edges or attaching a handle.
* Cardboard or Wood (Optional): For creating a handle or support.
* Clamps (Optional): To hold the reflector in place.
Construction Steps:
1. Simple White Reflector: If you purchased a white foam core board, congratulations! You already have a reflector. You can leave it as is or add a handle (see step 4).
2. Foil Reflector (Brighter, More Specular):
* Carefully crumple the aluminum foil and then smooth it out again. This adds texture and prevents harsh reflections.
* Spray the foam core board with spray adhesive.
* Carefully attach the crumpled and smoothed aluminum foil to the foam core. Ensure there are no large air bubbles.
* Trim any excess foil.
3. Fabric Reflector (Softer, Colored Light):
* Cut the fabric slightly larger than the foam core board.
* Spray the foam core with spray adhesive.
* Stretch the fabric tautly over the board and smooth it out.
* Wrap the excess fabric around the edges and secure it with spray adhesive or hot glue.
4. Adding a Handle or Support (Optional but Recommended):
* Handle: Cut a strip of cardboard or wood and attach it to the back of the reflector using strong tape or glue. This will make it easier to hold and position.
* Support: A simple stand can be fashioned using thick cardboard folded into a triangle and glued to the back of the reflector. Alternatively, you can use a commercial reflector stand.
Types of Reflection Surfaces and Their Effects:
* White: The most common and versatile. Produces a soft, diffused light, gently filling in shadows.
* Silver: Brighter than white, creating a more specular (direct) reflection. Good for adding a strong catchlight and boosting overall brightness. Can be too harsh if used directly in strong sunlight.
* Gold: Warms up the skin tone, adding a golden glow. Best used in the shade to avoid overly warm results.
* Black (Negative Fill): Absorbs light and increases contrast by darkening shadows. Useful for creating a more dramatic look.
Part 2: Using Your DIY Reflector Effectively
Now that you have your reflector, here's how to use it to improve your portraits:
1. Understanding Light Direction:
* Identify Your Light Source: Determine where the main light source is coming from (sun, window, lamp, etc.).
* Observe Shadows: Notice the areas on your subject's face that are in shadow. This is where the reflector will work its magic.
2. Positioning the Reflector:
* Angle is Key: The angle of the reflector is crucial. Experiment to find the angle that bounces the light back onto your subject's face, filling in the shadows.
* Position Relative to the Light Source: Usually, you'll position the reflector on the opposite side of your subject from the main light source. For example, if the sun is on the right, position the reflector on the left.
* Distance Matters: Start with the reflector close to your subject and gradually move it further away until you achieve the desired effect. Closer distances provide more intense fill light.
3. Reflector Placement Scenarios:
* Outdoors in Sunlight: Position the reflector to bounce sunlight into the shadows on your subject's face. Be mindful of the intensity. Direct silver reflection in strong sunlight can be overwhelming. Angle the reflector to diffuse the light if necessary.
* Indoors by a Window: Position the reflector on the opposite side of the window to bounce the window light back onto your subject. This softens shadows and evens out the lighting.
* Using Artificial Light: In a studio setting, position the reflector to bounce light from your strobe or continuous light source. This is a common technique for creating soft, flattering light.
* Overhead Light: Direct sunlight or overhead artificial light can create unflattering shadows under the eyes and nose. Position the reflector below your subject to fill in these shadows.
4. Working with an Assistant (Ideal):
* Having an assistant hold the reflector allows for precise positioning and adjustments. They can move the reflector to find the perfect angle and distance.
5. Solo Shooting (Still Possible):
* Using a Stand: If you don't have an assistant, a reflector stand is a great investment.
* Propping It Up: Get creative! Lean the reflector against a chair, wall, or other object.
* Holding It Yourself: In some situations, you can hold the reflector yourself while shooting, but this is less precise.
6. Observe the Effects and Adjust:
* Check Your LCD Screen: Review your shots on your camera's LCD screen to see the impact of the reflector. Pay attention to how the shadows are filled and how the skin tones look.
* Adjust the Angle and Distance: Based on what you see, adjust the angle and distance of the reflector until you achieve the desired effect.
* Look for the Catchlight: A catchlight is a small highlight in the subject's eyes. This adds life and sparkle to the portrait. The reflector should help create a catchlight.
Tips and Tricks:
* Don't Overdo It: Too much reflected light can flatten the image and make it look unnatural. Aim for a subtle, natural-looking fill.
* Consider the Background: Be aware of what the reflector is reflecting besides your subject. A brightly colored wall could introduce unwanted color casts.
* Experiment with Different Surfaces: Try different reflector surfaces (white, silver, gold) to see how they affect the light and the overall look of your portraits.
* Use a Reflector in Combination with Other Lighting Techniques: Reflectors can be combined with other lighting techniques, such as using a fill flash, to create more complex and sophisticated lighting setups.
* Practice Makes Perfect: The more you use your reflector, the better you'll become at understanding how it affects the light and how to position it effectively.
Safety Considerations:
* Sunlight: Be careful not to reflect direct sunlight into your subject's eyes. This can be harmful.
* Stability: Ensure the reflector is stable and won't fall over, especially in windy conditions.
* Sharp Edges: If you're using a utility knife to cut the foam core, be careful to avoid injury.
By following these steps, you can build a DIY reflector and use it effectively to improve your portrait photography. Experiment with different materials and techniques to find what works best for you and your style. Happy shooting!
