1. Understanding the Benefits of a Small Softbox:
* Softer Light: The primary benefit is diffusion. The light from your flash passes through the softbox material, scattering the light and reducing hard shadows.
* More Even Illumination: The larger surface area of the softbox, compared to a bare flash, helps create a more even spread of light across the subject.
* Directional Control: You can still control the direction of the light source, sculpting your subject's features.
* Portability: Small softboxes are relatively lightweight and easy to transport, making them suitable for on-location shoots.
2. Choosing the Right Small Softbox:
* Size Matters (Somewhat): While considered "small," consider the subject's size. A softbox that's too small will still produce harsh light, while one that's too large might be cumbersome. Generally, a 16x16" to 24x24" softbox is a good starting point for portraits.
* Mounting System: Ensure the softbox is compatible with your flash. Common mounting options include:
* Speed Ring: A metal ring that attaches to the softbox and allows you to mount it onto a speedlight or strobe.
* Universal Mounts: Some softboxes have adjustable straps or Velcro to fit various flash sizes. These are often less secure than speed rings.
* Internal Baffles: Look for softboxes with internal baffles (usually one or two layers of diffusion fabric inside). These help to further diffuse the light and prevent hot spots.
* Outer Diffuser: The outer diffuser is the primary diffusion material that spreads the light. Ensure it's a good quality, neutral white fabric.
3. Setting Up Your Equipment:
* Mounting the Softbox: Carefully attach the softbox to your flash using the appropriate mounting system. Make sure it's secure.
* Light Stand: Mount your flash and softbox onto a sturdy light stand. This gives you control over the height and angle of the light.
* Positioning Your Subject: Think about the background and the pose. A clean background will help focus the attention on your subject.
4. Flash Settings and Exposure:
* Flash Mode (TTL vs. Manual):
* TTL (Through-The-Lens): Your camera automatically adjusts the flash power. This is convenient for rapidly changing conditions but might not be the most consistent or controlled. You'll often need to use flash exposure compensation (FEC) to fine-tune the brightness.
* Manual: You set the flash power yourself. This requires more trial and error initially but gives you consistent results and greater control. Start with a low power setting (e.g., 1/32 or 1/64) and gradually increase it until you achieve the desired exposure.
* Camera Settings:
* Aperture: Controls the depth of field (how much of the image is in focus). A wider aperture (e.g., f/2.8, f/4) creates a shallow depth of field, blurring the background and isolating the subject. A narrower aperture (e.g., f/8, f/11) increases the depth of field, making more of the scene sharp.
* Shutter Speed: Controls how long the camera sensor is exposed to light. Use a shutter speed within your flash sync speed (typically 1/200th or 1/250th of a second). Faster speeds might result in banding.
* ISO: Keep the ISO as low as possible to minimize noise (e.g., ISO 100, ISO 200). Only increase it if you need more light and can't achieve it with aperture or flash power.
* Flash Exposure Compensation (FEC): If using TTL mode, adjust the FEC to fine-tune the brightness of the flash. Positive values make the flash brighter, negative values make it darker.
5. Positioning the Light:
This is the most crucial part. Experiment with different positions to find what works best for your subject. Here are some common starting points:
* 45-Degree Angle: Position the softbox at a 45-degree angle to the subject, slightly above eye level. This is a classic portrait lighting setup that creates flattering shadows and highlights.
* Frontal Lighting: Place the softbox directly in front of the subject. This produces a soft, even light with minimal shadows. It can be a good starting point, but might look a little flat.
* Side Lighting: Position the softbox to the side of the subject. This creates dramatic shadows and highlights, emphasizing texture and shape. Be careful, as this can be unflattering if not done well.
* Butterfly Lighting: Position the softbox directly in front of the subject and slightly above eye level. This creates a small, butterfly-shaped shadow under the nose.
* Clamshell Lighting: Uses two light sources. One is the main softbox placed above, and the other is a reflector (or a second softbox) placed below the subject to fill in shadows. This creates a very soft and flattering light.
6. Key Considerations and Tips:
* Distance: The closer the softbox is to your subject, the softer the light will be. However, getting too close can create a noticeable falloff in light, making the parts of the subject closest to the light brighter than the parts further away.
* Background: Be mindful of the background. Ensure it's not distracting or too bright. A darker background can help your subject stand out. You can use a background stand and paper/fabric backdrops for more control.
* Catchlights: Catchlights are the reflections of the light source in the subject's eyes. They add life and sparkle to portraits. Pay attention to the shape and position of the catchlights.
* Reflectors: Use a reflector to bounce light back into the shadows. This can brighten up the subject's face and reduce contrast. A white or silver reflector is a good choice.
* Shoot in RAW: Shooting in RAW format gives you more flexibility in post-processing. You can adjust the exposure, white balance, and other settings without losing image quality.
* Post-Processing: Use post-processing software (e.g., Adobe Lightroom, Capture One) to fine-tune your images. You can adjust the exposure, contrast, white balance, and sharpness. Also, you can subtly remove blemishes.
7. Common Mistakes to Avoid:
* Too Much Flash Power: Overpowering the flash can create harsh highlights and blown-out areas. Start with a low power setting and gradually increase it.
* Ignoring Ambient Light: Pay attention to the ambient light in the scene. Try to balance the flash with the ambient light to create a natural-looking image.
* Incorrect White Balance: Make sure your white balance is set correctly. If you're shooting in RAW, you can adjust the white balance in post-processing.
* Harsh Shadows: If you're getting harsh shadows, try moving the softbox closer to the subject or using a reflector to fill in the shadows.
* Distracting Backgrounds: Choose a simple, uncluttered background that doesn't distract from the subject.
In Summary:
Using a small softbox with your flash is a fantastic way to improve your portrait photography. By understanding the principles of light, experimenting with different positions, and paying attention to the details, you can create beautiful and flattering portraits with ease. Don't be afraid to experiment and find what works best for your style and subject. Good luck!
