Part 1: Building Your DIY Reflector
There are several ways to build a reflector, from very basic to a bit more robust. Here's a progression:
1. The Simplest: Foam Core Board
* Materials:
* White foam core board (available at craft stores, art supply stores, or even some dollar stores). Size depends on how much coverage you want - a 20x30 inch board is a good starting point.
* Construction: That's it! You're done.
* Pros: Extremely cheap, lightweight, portable, readily available.
* Cons: Not very durable, only provides a white bounce (though you can add other surfaces, see below).
2. The Cardboard Reflector:
* Materials:
* A large piece of cardboard (e.g., from a large box). Aim for at least 2x3 feet.
* Aluminum foil (heavy-duty is best) OR White paper/fabric OR Gold/Silver wrapping paper.
* Spray adhesive or strong tape.
* Scissors or a utility knife.
* Construction:
1. Cut the cardboard to your desired shape (rectangle, oval, etc.).
2. Smoothly cover one side of the cardboard with your chosen reflective material. If using foil, try to minimize wrinkles as much as possible for a smoother, more even reflection. Spray adhesive works well, but tape around the edges will also do the trick.
3. (Optional) Cover the back of the cardboard with a dark material (black fabric, black paper) to prevent light from bouncing through.
* Pros: Inexpensive, allows for different reflective surfaces.
* Cons: Can be bulky, aluminum foil can create harsh, specular highlights if not carefully applied.
3. The Fabric-Covered Frame Reflector (More Advanced)
* Materials:
* PVC pipe (3/4 inch is a good size). You'll need enough to create a frame of your desired size (e.g., a 3x4 foot frame).
* PVC pipe fittings (4 x 90-degree elbows).
* Reflective fabric (white, silver, gold, black). Ripstop nylon is a good durable option. Measure the fabric to be slightly larger than your frame size.
* Sewing machine or strong needle and thread (or fabric glue if you're averse to sewing).
* Optional: Bungee cords or clips to secure the fabric.
* Construction:
1. Cut the PVC pipe to the lengths needed for your frame.
2. Assemble the frame using the PVC fittings. You can glue the joints together for a more permanent frame, or leave them unglued for easier disassembly and storage.
3. Sew a "sleeve" or hem around the perimeter of your fabric. This sleeve should be large enough to slip over the PVC frame.
4. Slip the fabric over the frame. If the fit is snug, the fabric will stay in place. If it's a bit loose, use bungee cords or clips to secure it tautly.
5. (Optional) Create multiple fabric covers with different reflective properties (white, silver, gold, black) that you can easily swap out on the frame.
* Pros: Durable, versatile, easy to swap out reflective surfaces.
* Cons: Requires more time and materials to build.
Important Considerations for Reflective Surfaces:
* White: Provides a soft, neutral, and diffused light. Good for general fill light and softening shadows.
* Silver: Provides a brighter, more specular (directional) light than white. Good for adding a bit of punch and increasing contrast. Can be harsher than white.
* Gold: Provides a warm, golden light. Good for adding warmth to skin tones, especially in cool or overcast conditions.
* Black: A black reflector is actually an "anti-reflector" or "flag." It *absorbs* light, creating deeper shadows and preventing light from spilling onto unwanted areas.
* Matte vs. Glossy: Matte surfaces diffuse the light more, creating a softer, more even reflection. Glossy surfaces create more specular, directional light.
Part 2: Using Your Reflector for Portraits
Now that you have a reflector, here's how to use it to improve your portrait photography:
1. Understanding the Basics:
* Reflectors bounce light. They don't create light; they redirect existing light.
* Positioning is key. The angle of the reflector determines where the light bounces.
* Distance matters. The closer the reflector is to the subject, the more light it will bounce. However, get too close, and it might be visible in the shot.
2. Basic Reflector Placement:
* Outdoor Portraits (Sun as Main Light):
* Below the Face (Classic Fill Light): The most common use. Position the reflector below the subject's face, angled upwards to bounce sunlight into their shadows. This fills in the shadows under their eyes, nose, and chin, creating a more flattering look. A common starting point is at a 45-degree angle to the subject and the light source. Adjust the angle to control the amount of fill.
* Side Fill Light: If the sun is coming from the side, position the reflector on the *opposite* side of the subject to fill in the shadows. This can create a more dramatic and sculpted look.
* Overhead Fill Light (Difficult, Requires an Assistant): If the sun is directly overhead, you can try to position the reflector *above* the subject, angled down to create a more even light. This is tricky to manage without an assistant to hold the reflector.
* Indoor Portraits (Window Light as Main Light):
* Opposite the Window: Position the reflector on the side opposite the window to bounce light back onto the subject, filling in shadows and creating a more balanced exposure.
* Under the Chin: Same principle as the outdoor example.
3. Tips for Using Reflectors Effectively:
* Start Subtle: Don't overdo it! Begin with a subtle amount of fill light and gradually increase it until you achieve the desired effect. Too much fill light can make the portrait look flat and unnatural.
* Watch for Catchlights: The reflection from the reflector will create a catchlight in the subject's eyes. Make sure the catchlight is in a pleasing position and doesn't look distracting. Ideally, you want a single, well-defined catchlight in each eye.
* Consider the Background: Be aware of what the reflector is reflecting. Make sure you're not accidentally bouncing light onto unwanted areas of the background.
* Use an Assistant (If Possible): Having an assistant to hold the reflector makes it much easier to position and adjust it accurately. They can also move the reflector slightly to create subtle changes in the lighting.
* Experiment with Angles and Distances: The best way to learn how to use a reflector is to experiment with different angles and distances. Take lots of photos and see how the lighting changes.
* Pay Attention to Skin Tones: Use a white reflector for neutral skin tones, gold for warmth, and silver for a brighter, more contrasty look.
* Diffused Light is Your Friend: In bright sunlight, consider using a diffuser (scrim) *in addition* to your reflector. The diffuser will soften the direct sunlight, making the light more manageable and flattering. You can often find 5-in-1 reflectors that include a diffuser as one of the options.
* Wind is the Enemy: Outdoors, even a slight breeze can make holding a reflector difficult. Consider using a reflector holder (available online or at photography stores) or improvising with weights to keep the reflector steady.
4. Common Mistakes to Avoid:
* Overpowering the Main Light: The reflector should be used to *supplement* the main light, not to replace it. The main light should still be the dominant light source.
* Creating Unnatural Shadows: Pay attention to the shadows created by the reflector. Make sure they look natural and don't clash with the shadows created by the main light.
* Using the Wrong Reflector for the Situation: Choosing the right reflective surface (white, silver, gold) is crucial. Using a gold reflector in already warm light can make the skin tones look orange.
* Having the Reflector Visible in the Shot: Make sure the reflector is out of the frame.
* Ignoring the Subject's Expression: While lighting is important, don't forget to pay attention to the subject's expression and pose. A well-lit but awkward portrait is still an awkward portrait.
In Summary:
Building and using a reflector is a simple and effective way to improve your portrait photography. By understanding the principles of light and shadow, and by experimenting with different reflective surfaces and positioning techniques, you can create more flattering and professional-looking portraits. Good luck, and have fun!
