Part 1: Building Your DIY Reflector
You have several options here, ranging from super-cheap to a bit more involved. Let's explore the most common:
Option 1: The Cardboard Core & Foil (Simplest and Cheapest)
* Materials:
* Large piece of sturdy cardboard (a shipping box works great). The size depends on your needs. 2x3 feet is a good starting point.
* Aluminum foil (heavy-duty is best). Use the matte side if you have the option.
* Tape (duct tape or packing tape).
* Scissors or a utility knife.
* Construction:
1. Cut the Cardboard: If necessary, cut the cardboard to your desired size and shape (oval, rectangle). Rounded corners prevent creasing.
2. Apply the Foil: Cover one side of the cardboard entirely with foil. Pull it taut to minimize wrinkles (wrinkles create less predictable light).
3. Secure the Foil: Tape the foil tightly around the edges to the back of the cardboard. Make sure the foil is well-secured.
* Pros: Extremely cheap, easy to make, lightweight.
* Cons: Foil can be fragile and prone to wrinkles. Reflects a harsh, specular light (more on this later).
Option 2: The Foam Board & Fabric (More Control Over Light)
* Materials:
* White foam board (available at craft stores, art supply stores). Again, size depends on your needs. 2x3 feet is a good size.
* Optional: Black foam board (for blocking light – a "flag")
* Fabric (see below for options).
* Spray adhesive (optional, but recommended for a cleaner look).
* Scissors or a utility knife.
* Fabric Choices:
* White Fabric (Softest Light): Bleached muslin, white broadcloth, or even a white bedsheet will work. Make sure it's fairly opaque (you don't want light shining through).
* Silver Fabric (More Specular): Shiny silver material, like ripstop nylon with a silver backing (often used for kite making), or even reflective emergency blankets.
* Gold Fabric (Warmer Light): Gold lame fabric or gold mylar. (use sparingly as gold light can create skin tone issues)
* Construction:
1. Cut the Foam Board: Cut the foam board to your desired size and shape.
2. Attach the Fabric:
* Spray Adhesive Method: Lightly spray the foam board with adhesive. Carefully lay the fabric onto the foam board, smoothing it out to avoid wrinkles and bubbles. Trim the excess fabric around the edges.
* Wrapping Method: Cut the fabric large enough to wrap around the edges of the foam board. Secure the fabric to the back of the foam board with tape or glue.
3. Optional: Black Foam Board Flag: Cut a piece of black foam board and attach it to the back of the reflector (or create a separate flag) to block light from specific areas.
* Pros: More durable than foil, allows you to choose the reflectivity (and therefore the quality of light) by choosing different fabrics. Foam board is rigid and easier to handle.
* Cons: Slightly more expensive and requires more effort to make.
Option 3: Folding Car Windshield Sun Shade (Portable and Convenient)
* Materials:
* Folding car windshield sun shade (the silver, reflective type).
* Construction:
* None! Just unfold it. You might want to reinforce the edges with duct tape for durability.
* Pros: Extremely portable, lightweight, and readily available. Already built! Offers a reflective silver surface.
* Cons: Not as large as the other options. Can be a bit flimsy.
Part 2: Understanding Reflector Surfaces and Light Quality
The surface of your reflector drastically affects the type of light it produces:
* White: Creates the softest, most diffused light. Ideal for subtle fill light, especially for portraits.
* Silver: Reflects more light than white. Offers a brighter, more specular (direct) light. Good for adding a bit of punch or sparkle to the eyes (catchlights). Can be harsh if overused.
* Gold: Reflects a warm, golden light. Use sparingly and with caution, as it can affect skin tones. Good for adding warmth on a cloudy day, or for certain creative effects.
* Black (Flag): Does *not* reflect light. It absorbs it. Used to block light from unwanted areas, creating shadows or more defined contrast.
Part 3: How to Use a Reflector for Portrait Photography
Now, the important part! Here's how to use your reflector to improve your portraits.
1. Assess the Existing Light:
* Direction: Where is the main light source coming from? Is it sunlight, a window, or an artificial light?
* Quality: Is the light hard (direct, creates strong shadows) or soft (diffused, creates gentle shadows)?
* Strength: How bright is the light?
2. Determine Your Goal:
* Fill Light: Do you want to fill in shadows on your subject's face to create a more even exposure? This is the most common use of a reflector.
* Rim Light: Do you want to create a highlight along the edge of your subject to separate them from the background?
* Catchlights: Do you want to add a sparkle to your subject's eyes?
* Warmth: Do you want to add warmth to the scene?
3. Reflector Placement (The Key!):
* General Placement: The reflector should be positioned on the *opposite* side of the main light source. For example, if the sun is on the right side of your subject, place the reflector on their left.
* Angle and Distance: This is where experimentation comes in!
* Angle: Adjust the angle of the reflector to bounce the light onto the desired area of your subject's face (usually the shadow side).
* Distance: The closer the reflector, the more light it will reflect. The farther away, the less light.
4. Reflector Holder (Important!):
* Holding a reflector while taking photos is tricky. Here are solutions:
* Assistant: The easiest way is to have a friend or assistant hold the reflector.
* Reflector Arm/Holder: You can buy reflector arms that attach to light stands. These are very helpful for solo shoots.
* DIY Reflector Stand: You can create a makeshift stand using clamps and a light stand or tripod.
* Lean it against something A wall, a chair, a tree. It's not perfect but if you're alone and in a pinch it works.
5. Working with Sunlight:
* Golden Hour: The soft, warm light of golden hour (the hour after sunrise and the hour before sunset) is ideal for portraits. A white reflector will enhance this beautiful light.
* Overhead Sun (Harsh Light): Midday sun is the hardest to work with. Use a reflector to fill in the harsh shadows under the eyes, nose, and chin. Consider using a white or silver reflector, depending on the amount of fill you need.
* Open Shade: Position your subject in open shade (shade that is not cast from a small source, like dappled light through trees). Use a reflector to bounce light back onto their face.
6. Working with Window Light:
* Directional Light: Window light can be beautiful, but it can also create strong shadows. Use a reflector to fill in those shadows and create a more balanced exposure.
* Positioning: Place your subject near a window, and position the reflector on the opposite side of the window to bounce light back onto their face.
7. Tips and Considerations:
* Experimentation is Key: There's no single "right" way to use a reflector. Experiment with different angles, distances, and surfaces to see what works best for your subject and lighting conditions.
* Subtlety is Often Best: Avoid overusing the reflector. The goal is to enhance the existing light, not to create artificial-looking light.
* Watch for Glare: Be careful not to reflect too much light into your subject's eyes, which can cause them to squint. Angle the reflector slightly downward to avoid this.
* Wind: Wind can be a challenge when using reflectors, especially large ones. Use weights or a sturdy stand to prevent the reflector from blowing over.
* Subject Comfort: Pay attention to your subject's comfort. Make sure the reflected light is not too bright or uncomfortable for them.
* Practice! The more you practice using a reflector, the better you'll become at anticipating its effects and creating beautiful, well-lit portraits.
Example Scenario:
Let's say you're taking a portrait outdoors on a slightly overcast day. The light is fairly flat, and there are some shadows under your subject's eyes.
1. Goal: Fill in the shadows and add a bit of life to the portrait.
2. Solution: Use a white foam board reflector.
3. Placement: Position the reflector on the opposite side of the main light source (the overcast sky). Adjust the angle and distance of the reflector until you see the shadows under your subject's eyes soften.
In summary, reflectors are a versatile and inexpensive tool that can dramatically improve your portrait photography. By understanding the principles of light and shadow, and by experimenting with different reflector surfaces and placements, you can create beautiful, well-lit portraits that capture the essence of your subject.
