1. Choosing the Right Small Softbox:
* Size: Aim for a size that's large enough to wrap around your subject's face but small enough to be easily manageable, especially when shooting on location. A size between 12"x16" and 24"x24" is a good starting point. Larger softboxes will give you softer light, but are less portable.
* Shape: Rectangular softboxes are great for full-body shots or when you want a defined highlight. Square softboxes are versatile. Octagonal softboxes often produce more pleasing round catchlights in the eyes.
* Mounting System: Ensure the softbox is compatible with your flash. Most use a speed ring that attaches to the flash head. Bowens mount compatibility is a plus, allowing you to use a wider range of light modifiers.
* Internal Baffles: Look for a softbox with at least one internal baffle (a white diffuser inside) to further soften the light. Two baffles offer even softer light.
* Outer Diffuser: The outer diffuser is essential for spreading the light evenly.
2. Setting Up Your Flash and Softbox:
* Attach the Speed Ring: Connect the speed ring to your flash. Make sure it's securely fastened.
* Assemble the Softbox: Follow the manufacturer's instructions to assemble the softbox. This usually involves inserting rods into the speed ring.
* Mount the Flash: Slide the assembled softbox onto the speed ring and tighten the screws.
* Test the Flash: Turn on your flash and do a test flash to make sure everything is working.
3. Positioning the Softbox for Portraits:
* Key Light: The softbox will act as your main (key) light. Place it to one side of your subject, slightly in front. This creates a classic and flattering light pattern.
* Angle: Experiment with the angle of the softbox relative to your subject.
* 45-degree angle: A good starting point. It provides a balanced mix of light and shadow.
* Further back: Creates more dramatic shadows.
* More directly in front: Produces a flatter, less sculpted look.
* Height:
* Slightly above eye level: Creates a natural and appealing light. Too high can create unflattering shadows under the eyes and nose.
* At eye level: Can look flat.
* Below eye level: Gives a horror-movie effect (usually undesirable for portraits).
* Distance:
* Close to the subject: Creates softer light and more dramatic falloff (the transition from light to shadow).
* Further away: Creates harder light and less falloff.
* Feathering: Angle the softbox slightly away from your subject so that the *edge* of the light beam falls on them. This is called "feathering" and helps to soften the light even further.
4. Flash Power Settings:
* Start Low: Begin with a low flash power setting (e.g., 1/16th or 1/32nd power) and gradually increase it until you achieve the desired exposure. Chimping (checking the LCD screen) is helpful.
* Use a Light Meter (Optional): For more precise control, use a handheld light meter to measure the light output from the softbox at your subject's face.
* TTL vs. Manual:
* TTL (Through-The-Lens) Metering: Your camera automatically adjusts the flash power based on the scene's lighting. This is easier for beginners but can be less consistent.
* Manual Mode: You manually set the flash power. This gives you more control and consistency but requires more practice. Many photographers prefer manual mode for portrait work.
5. Camera Settings:
* Aperture: Choose an aperture that gives you the desired depth of field. A wider aperture (e.g., f/2.8 or f/4) will create a shallow depth of field, blurring the background and focusing attention on the subject. A narrower aperture (e.g., f/8 or f/11) will give you more depth of field, keeping more of the scene in focus.
* Shutter Speed: Your shutter speed will usually be dictated by your flash sync speed (typically around 1/200th or 1/250th of a second). Going above the sync speed will result in a black band appearing in your image.
* ISO: Keep your ISO as low as possible (e.g., ISO 100 or 200) to minimize noise.
* White Balance: Set your white balance appropriately for the scene's lighting. Flash is typically around 5500K (daylight).
6. Modifiers and Additional Lighting:
* Reflector: Use a reflector (white, silver, or gold) to bounce light back into the shadow areas of your subject's face. This helps to fill in shadows and create a more balanced look.
* Fill Flash: You can use a second flash (usually at a lower power) as a fill light to further reduce shadows. Position it on the opposite side of your subject from the key light.
* Background Light: A separate flash or light source can be used to illuminate the background, creating separation between the subject and the background.
* Gels: Add colored gels to your flash to create creative lighting effects.
7. Tips for Better Portraits:
* Practice: Experiment with different softbox positions, flash power settings, and camera settings to see what works best for you.
* Posing: Learn basic posing techniques to flatter your subjects.
* Eye Contact: Encourage your subjects to make eye contact with the camera.
* Focus on the Eyes: Sharp focus on the eyes is critical for compelling portraits.
* Shoot in RAW: Shooting in RAW format gives you more flexibility in post-processing.
* Post-Processing: Use software like Adobe Lightroom or Capture One to fine-tune your images.
Key Advantages of Using a Small Softbox:
* Softer Light: Reduces harsh shadows and creates a more flattering look.
* More Control: Allows you to shape and direct the light more precisely than using a bare flash.
* Portability: Smaller softboxes are relatively lightweight and easy to transport.
* Affordable: Compared to larger studio lighting equipment, small softboxes are a cost-effective option.
Common Mistakes to Avoid:
* Overpowering the Ambient Light: Make sure the flash is the dominant light source. Otherwise, you may end up with a mixed lighting situation that looks unnatural.
* Positioning the Softbox Too Far Away: The further away the softbox is, the harder the light will be.
* Using Too Much Flash Power: Overexposing the image can result in blown-out highlights and a harsh look.
* Ignoring the Background: Pay attention to the background and make sure it complements your subject.
By understanding these concepts and practicing regularly, you can use a small softbox with your flash to create stunning portraits that your subjects will love. Remember to experiment and find what works best for your style and the look you're trying to achieve. Good luck!
