1. Understanding the Benefits
* Softer Light: The primary benefit is softening the light. The softbox diffuses the flash output, making it less harsh and creating a gentler, more flattering light on your subject's face. This reduces harsh shadows and highlights.
* More Even Illumination: It distributes the light more evenly across the subject, minimizing dark spots and creating a more balanced exposure.
* Directional Control: While soft, the light is still directional. You can control the direction and angle of the light to sculpt your subject's features.
* Portable and Affordable: Small softboxes are often relatively inexpensive and easy to transport, making them a good option for on-location shoots.
2. Equipment You'll Need
* Flash (Speedlight/Strobe): This is your light source. Make sure your flash is compatible with your camera and can be triggered remotely.
* Small Softbox: Choose a size appropriate for your needs. Common sizes range from 8x8 inches to 16x16 inches. Consider the shape (square, rectangular, octagonal).
* Speedlight Bracket/Adapter: This attaches the softbox to your flash. There are various options, including simple adapters that slide onto your flash or more robust brackets with tilting mechanisms.
* Light Stand (Optional, but Highly Recommended): Allows you to position your softbox precisely and keep it stable.
* Wireless Flash Trigger (Optional, but Very Useful): Allows you to fire your flash remotely, giving you greater control over its placement and eliminating the need for a direct connection to your camera. Examples include PocketWizards, Godox X-system, or Yongnuo triggers.
* Camera: Set your camera to manual mode (or aperture priority if you're comfortable) for consistent results.
* Batteries: Make sure both your flash and trigger have fresh batteries!
3. Setting Up Your Gear
1. Assemble the Softbox: Follow the manufacturer's instructions to assemble the softbox. This usually involves unfolding it and attaching the diffuser fabric.
2. Attach Flash to Adapter: Securely attach your flash to the speedlight bracket or adapter. Ensure it is firmly in place.
3. Attach Softbox to Flash: Attach the softbox to the flash/adapter assembly.
4. Mount on Light Stand (if using): Mount the entire setup onto your light stand and tighten the screws to keep it secure.
5. Trigger Setup: If using a wireless trigger, attach the transmitter to your camera's hot shoe and the receiver to your flash unit. Set the correct channel on both the transmitter and receiver.
6. Position the Light: This is crucial. Start with the softbox positioned about 45 degrees to the side and slightly above your subject.
4. Camera Settings and Flash Power
* Camera Mode: Manual (M) is recommended for full control.
* Aperture: Controls the depth of field and overall exposure. Start around f/5.6 or f/8 for portraits with a good amount of background blur, then adjust based on your desired look. Wider apertures (e.g., f/2.8, f/4) will blur the background more but require more precise focusing.
* Shutter Speed: Primarily controls ambient light. Set it to 1/200th or 1/250th of a second (or your camera's flash sync speed) to avoid banding or shutter curtains in your photos. Don't go faster than your camera's flash sync speed.
* ISO: Keep ISO as low as possible (e.g., ISO 100 or 200) to minimize noise.
* White Balance: Set your white balance according to your environment (e.g., Daylight, Cloudy, Flash). Consider using a grey card to ensure accurate white balance in post-processing.
* Flash Power: Start with a low flash power setting (e.g., 1/32 or 1/16) and gradually increase it until you achieve the desired exposure. Take test shots and check your camera's histogram to avoid overexposure. You can also use TTL (Through The Lens) mode on your flash, but using manual mode will give you more control over the light.
5. Positioning the Light
This is where experimentation comes in! Here are some common lighting setups:
* 45-Degree Angle (Classic Portrait Lighting): Place the softbox about 45 degrees to the side and slightly above your subject. This creates pleasing shadows that sculpt the face. Move the light closer or farther to adjust the size and intensity of the shadows.
* Butterfly Lighting: Place the softbox directly in front of your subject and slightly above eye level. This creates a small, butterfly-shaped shadow under the nose and even lighting across the face. Good for minimizing wrinkles.
* Loop Lighting: Similar to 45-degree lighting, but the shadow of the nose should be on the same side of the face as the light.
* Rembrandt Lighting: Position the light so that a triangle of light appears on the cheek opposite the light source. This is a more dramatic lighting style.
* Feathering the Light: Don't point the softbox directly at your subject. Instead, angle it slightly away, so the edge of the light beam falls on your subject. This can create a softer, more diffused light.
6. Key Considerations and Tips
* Distance: The closer the softbox is to your subject, the softer the light will be. Moving it farther away will make the light harder and increase the shadow contrast.
* Background: Pay attention to the background. A dark background will accentuate the light on your subject, while a light background can bounce light back and fill in shadows.
* Diffusion: If you find the light still too harsh, consider adding an extra layer of diffusion (e.g., a scrim or a larger diffuser panel).
* Bouncing Light: If you don't have a second light, you can use a reflector (white, silver, or gold) to bounce some of the flash's light back onto the shadow side of your subject's face.
* Eye Catchlights: Ensure there's a catchlight (a reflection of the light source) in your subject's eyes. It adds life and sparkle to the image. Position the light accordingly.
* Practice, Practice, Practice: Experiment with different lighting positions, camera settings, and flash power levels to see what works best for you and your subjects.
* Watch for Overexposure: Check your camera's histogram. The histogram is a graph that shows the distribution of tones in your image, from darkest to brightest. Make sure the histogram doesn't "clip" on the right side, indicating blown-out highlights.
* Consider the Size of the Softbox: The size of the softbox relative to your subject determines the softness of the light. A larger softbox will produce softer light than a smaller one. However, even a small softbox is better than direct flash.
* Post-Processing: You can further refine your images in post-processing software like Adobe Lightroom or Capture One. Adjust exposure, contrast, white balance, and sharpness as needed.
Example Setup and Settings:
* Subject: Portrait of one person, waist-up.
* Flash: Speedlight set to manual mode.
* Softbox: 16x16 inch softbox.
* Light Stand: Used to position the light.
* Camera: Canon EOS 5D Mark IV
* Lens: 85mm f/1.8
* Settings:
* Camera Mode: Manual (M)
* Aperture: f/5.6
* Shutter Speed: 1/200 sec
* ISO: 100
* White Balance: Flash
* Flash Power: Starting at 1/16 power, adjust as needed.
* Positioning: Softbox positioned about 45 degrees to the side and slightly above the subject. Adjust distance to fine-tune the light.
By following these steps and experimenting with different techniques, you can use a small softbox with your flash to dramatically improve your portrait photography and create beautiful, flattering images.
