I. Understanding the Concept:
The key to a successful black background portrait is understanding that you're not actually *creating* a black background as much as you are *eliminating* light from falling on it. It's about controlling the light source and its falloff.
II. Equipment:
* Camera: Any DSLR or mirrorless camera will work.
* Lens: A portrait lens is ideal (50mm, 85mm, 100mm, etc.), but you can use other focal lengths too. A wider aperture (f/1.8, f/2.8) will help blur the background and isolate your subject.
* Light Source: This is crucial. Options include:
* Studio Strobe/Flash: Provides the most control and power.
* Speedlight (External Flash): Portable and versatile, but may require higher ISO or wider aperture.
* Continuous Light (LED or Tungsten): Good for seeing the effect in real-time, but often less powerful than flash.
* Light Modifier (Optional but Recommended):
* Softbox: Creates soft, diffused light.
* Umbrella: Another option for soft light, typically more portable than a softbox.
* Reflector: Can bounce light back onto the subject to fill in shadows.
* Snoot or Grid: To create a focused light beam that will have a harsh fall-off.
* Background: Anything that can be positioned behind your subject:
* Black Fabric: Velvet, felt, or other dark, light-absorbing material. Wrinkle-free is best.
* Black Paper Roll: Seamless and provides a clean, even surface.
* Dark Wall: Painted matte black. Make sure it's truly dark and non-reflective.
* Light Meter (Optional): Helpful for precise flash exposure, but not essential if you understand your camera settings.
* Tripod (Optional): Recommended for consistent framing and sharper images, especially in low light or when using longer shutter speeds.
III. Setting Up Your Shoot:
1. Choose Your Location: Select a room where you can control the ambient light (turn off overhead lights, close blinds).
2. Position Your Background: Place your background behind where your subject will stand or sit. The farther away from the subject the better.
3. Position Your Subject: Have your subject stand or sit far enough in front of the background that light falling on them won't spill onto the background. Typically, 6-10 feet of separation is a good starting point. The further the subject from the background, the less likely it is that the subject's light will also light up the background.
4. Set Up Your Light Source:
* Single Light: Place your light to the side or slightly in front of your subject. Experiment with the angle to create interesting shadows.
* Multiple Lights: A key light provides the main illumination. A fill light (lower power) can be used on the opposite side to soften shadows.
* Modify the Light: Attach your softbox or umbrella to your light source.
5. Camera Settings:
* ISO: Start with the lowest possible ISO (e.g., ISO 100) to minimize noise. Increase only if necessary.
* Aperture: Choose an aperture that gives you the desired depth of field (e.g., f/2.8 for a blurred background, f/5.6 for more sharpness).
* Shutter Speed: Set your shutter speed based on your light source and desired exposure. If using flash, the maximum sync speed of your camera will limit your shutter speed. If using continuous light, adjust the shutter speed to achieve the desired exposure. Generally, start around 1/125th or 1/200th of a second.
* Metering Mode: Use spot metering and meter off your subject's face.
IV. Taking the Shot (and How to Get the Black Background):
1. Turn Off All Ambient Light: This is crucial. You want only the light from your light source to illuminate your subject.
2. Take a Test Shot: Take a photo and review the results on your camera's LCD screen.
3. Adjust Exposure:
* Subject Too Dark: Increase the power of your light source, widen your aperture, or increase the ISO.
* Subject Too Bright: Decrease the power of your light source, narrow your aperture, or decrease the ISO.
* Background Not Black Enough: This is the key. The background is likely not black enough because *some* light is still hitting it. Here's how to fix it:
* Increase Subject Distance from Background: Move your subject further away from the background.
* Decrease Light Spill: Use a snoot or grid on your light source to focus the light more narrowly on the subject and prevent it from spreading to the background. Alternatively, use barn doors to cut off light from spilling onto the background.
* Lower Light Power: Sometimes, even a little bounce is enough to brighten the background, so by lowering the power of the flash or constant light, the background can appear more dark.
* Increase Falloff: The more dramatic the falloff, the less light reaching the background. Use a smaller light modifier to achieve a faster falloff.
4. Focus: Focus carefully on your subject's eyes.
5. Take More Shots! Experiment with different poses, expressions, and lighting angles.
V. Post-Processing (Editing):
While the goal is to get the black background in-camera, post-processing can help refine the image:
* Minor Adjustments:
* Exposure: Fine-tune the overall brightness.
* Contrast: Add a bit of contrast to make the subject pop.
* Blacks: Pull down the blacks slider to deepen the black background further. Be careful not to clip detail in the shadows of your subject.
* Clarity/Texture: Enhance sharpness and detail.
* Local Adjustments:
* Dodging and Burning: Subtly lighten or darken specific areas of the subject.
* Brush Tool: Can be used to darken any remaining bright spots in the background.
Tips for Success:
* Practice: Experiment with different lighting setups to see what works best.
* Monitor Your Histogram: Make sure you're not clipping highlights or shadows.
* Pay Attention to Detail: Clean up any distracting elements in the background.
* Communicate with Your Subject: Guide them with posing and expressions.
* Use a Hair Light (Optional): A separate light aimed at the subject's hair can add separation and definition. Be very careful with this light, as even a slight spill can ruin the black background.
* Check for Light Spill: Look for stray light hitting the background on your camera's live view or in test shots.
By following these steps and practicing, you can create professional-looking portraits with striking black backgrounds. Good luck!
