Part 1: Building Your DIY Reflector
Materials You'll Need:
* Core Material:
* Foam Board: This is the most common and recommended option. Get a piece of foam board (usually 20x30 inches is a good starting point) from a craft store, dollar store, or art supply store. Consider white, but you can also get black for blocking light or different colors for subtle effects.
* Cardboard: A large piece of cardboard (like from a flattened box) will work in a pinch. It won't be as smooth or rigid as foam board.
* Reflective Car Sunshade: These are readily available and already have a reflective surface. You might need to cut and attach it to a backing for easier handling.
* Reflective Covering (Choose one or more):
* White:
* White Paper: Plain white printer paper or poster board.
* White Fabric: Muslin, cotton, or a thin white sheet.
* White Paint: Matte or satin finish. Avoid gloss paint, which can create harsh highlights.
* Silver:
* Aluminum Foil: The crinkled side creates a softer, more diffused light. The smooth side is more reflective but can be harsher.
* Silver Reflective Tape: Found in hardware stores.
* Emergency Blanket (Mylar): Very lightweight and highly reflective. Can be a bit crinkly.
* Gold:
* Gold Wrapping Paper: Look for a matte or satin finish.
* Gold Fabric: Similar to above, consider a smooth satin for gold.
* Black:
* Black Foam Board: This can be used to subtract light rather than reflect it.
* Black Fabric: Duvetyne or similar light-absorbing fabric.
* Adhesive:
* Spray Adhesive: Works well for adhering paper or fabric to foam board.
* Tape: Packing tape, duct tape, or masking tape (for temporary attachments).
* Glue Stick: Works for smaller areas with paper.
* Cutting Tools:
* Utility Knife or Box Cutter: For cutting foam board or cardboard. Be careful! Use a ruler or straight edge as a guide, and cut on a safe surface.
* Scissors: For cutting paper or fabric.
* Optional:
* Handle: A dowel rod, stick, or even a sturdy piece of cardboard can be attached to the back for easier holding.
* Stand: If you want the reflector to be hands-free, consider a small light stand with a clamp or a DIY support system.
* Sandpaper: For smoothing rough edges if you're using cardboard.
Steps:
1. Prepare Your Core Material:
* If using foam board or cardboard, cut it to the desired size and shape. A rectangle is the most common and versatile. If you are using cardboard consider sanding down the edges, so you don't get cut from the exposed cardboard.
* If using a car sunshade, cut it to size and attach it to a backing (foam board or cardboard) if needed.
2. Apply the Reflective Covering:
* White: Spray adhesive evenly onto the foam board. Carefully attach the white paper or fabric, smoothing out any wrinkles or bubbles. If using paint, apply several thin, even coats, allowing each coat to dry completely.
* Silver/Gold: Apply aluminum foil or wrapping paper using spray adhesive or tape. Try to minimize wrinkles (unless you *want* the diffused look of crinkled foil).
* Black: Use spray adhesive or tape to attach black fabric to foam board.
3. Reinforce Edges (Optional):
* Wrap the edges with tape for a cleaner look and to prevent the reflective covering from peeling.
4. Add a Handle or Stand (Optional):
* Attach a dowel rod or stick to the back with strong tape or glue.
* For a stand, you can create a cardboard support that folds out, or use a clamp attached to a light stand.
Examples:
* Simple White Reflector: White foam board is your core. Cover it with white poster board attached with spray adhesive. Done!
* Silver Reflector: Foam board covered in aluminum foil (crinkled or smooth) attached with spray adhesive.
* 2-in-1 Reflector: Cover one side of the foam board with white paper and the other side with aluminum foil. This gives you two reflector options in one.
Part 2: Using Your DIY Reflector for Portraits
Understanding Light and Reflection:
* Key Light: This is your main light source (sun, window, or artificial light).
* Shadows: Shadows are created when the key light is blocked. Shadows can make your subject look more defined or less defined.
* Reflector's Purpose: The reflector bounces light back into the shadows, filling them in and reducing contrast. This creates a more flattering and even illumination.
Steps for Using the Reflector:
1. Position Your Subject and Key Light:
* Place your subject in a location where they are well-lit by your key light source. Experiment with different angles to see how the light falls on their face.
2. Position the Reflector:
* This is the most important part. You want to position the reflector on the *opposite* side of the subject from the key light.
* Angle the reflector so that it bounces light back onto the subject's face, specifically filling in the shadows.
* Important: You need to see the reflected light hitting your subject's face. Have your subject tell you when they see the reflection of light in their eyes.
* Start with the reflector at a 45-degree angle relative to the subject and key light, and adjust it from there.
3. Distance and Angle Adjustments:
* Distance: The closer the reflector is to your subject, the brighter the reflected light will be. Experiment with distance to achieve the desired level of fill.
* Angle: Adjusting the angle of the reflector changes where the light falls on your subject. Fine-tune the angle to eliminate harsh shadows or create subtle highlights.
4. Types of Reflective Surfaces and Their Effects:
* White: Provides a soft, neutral fill light. It's great for general shadow reduction and a natural look.
* Silver: Creates a brighter, more specular (mirror-like) fill light. Use it when you need more light or want to add a bit of punch and highlights.
* Gold: Adds a warm, golden tone to the fill light. Use sparingly, as it can easily become overpowering. Good for portraits with warm skin tones or for creating a sunset effect.
* Black: Doesn't reflect light; instead, it *subtracts* it. Use it to create deeper shadows or to control light spill. You might position it to the side of your subject to narrow the light source or to block light from hitting a background element.
5. Test Shots and Refinements: Take some photos to see how you like the light. Refine the angle and position until you get the ideal lighting.
6. Use a Stand/Assistant (If Needed): Reflectors need to be held in place, and this can be tough to do by yourself. A light stand with a reflector clamp or a willing assistant will make the process much easier.
Tips and Tricks:
* Observe the Light: Pay close attention to how the light changes as you adjust the reflector. The slightest change in angle can make a big difference.
* Avoid Harsh Glare: Be mindful of where the reflected light is going. You don't want to shine it directly into the subject's eyes.
* Diffusion: If the reflected light is too harsh (especially with silver), try diffusing it by holding a thin white fabric (like a handkerchief) in front of the reflector.
* Natural Light is Best: Reflectors work best when used with natural light (sunlight or window light).
* Practice Makes Perfect: Experiment with different reflector positions, angles, and distances to see what works best for different lighting conditions and subjects.
* The eye is more important than the tools. Your ability to "see" the light and how the reflector is affecting it is the most crucial element.
Safety Considerations:
* Sharp Objects: Be careful when using utility knives or box cutters. Cut on a safe surface and use a ruler as a guide.
* Reflected Sunlight: Avoid shining direct sunlight into anyone's eyes (including your own!).
* Spray Adhesive: Use spray adhesive in a well-ventilated area.
* Don't reflect light into traffic or other people's eyes!
In Summary:
Building a DIY reflector is a simple and effective way to improve your portrait photography. By understanding how light works and experimenting with different reflector positions and materials, you can create beautiful, flattering portraits with a minimal investment. Good luck!
