I. Understanding the Goal: True Black
The key to a good black background portrait is achieving a truly black background, not just a dark gray. This means no visible texture, details, or shadows on the background. The subject should be the only thing illuminated.
II. Methods for Achieving a Black Background:
Here are a few different approaches, from easiest to most technically demanding:
A. Using a Black Backdrop (Easiest)
* The Backdrop:
* Material: Black velvet, black felt, black muslin, or even a large sheet of black paper. Velvet is often considered the best for absorbing light and minimizing reflections, but it can be more expensive.
* Size: Ensure the backdrop is large enough to cover the entire area behind your subject, especially if they will be moving. Consider the height and width.
* Placement: Position the backdrop far enough behind your subject so that the light hitting them doesn't spill onto the background. The further away, the better. Aim for at least 4-6 feet.
* Lighting:
* Directional Light: Use a directional light source (e.g., a strobe with a softbox, a beauty dish, or even a single speedlight) to light only the subject. The more directional, the easier it is to control spill.
* Feathering the Light: "Feather" the light, which means aiming the light source slightly *away* from the subject. This gives a softer, more pleasing look and helps control light falloff onto the background.
* Light Modifiers: Use softboxes or umbrellas to diffuse the light and avoid harsh shadows on the subject's face.
* No Light on the Background! This is crucial. Make sure *no* light is directly hitting the backdrop. Use flags (pieces of black fabric or cardboard) to block any spill.
* Camera Settings:
* Aperture: Use a wide aperture (low f-number, like f/2.8 or f/4) to create shallow depth of field and further isolate the subject from the background.
* ISO: Keep the ISO as low as possible to minimize noise.
* Shutter Speed: Adjust the shutter speed to properly expose the subject. With strobes, the shutter speed won't usually matter as much as it does with ambient light (it mainly dictates the ambient light).
* Metering: Use spot metering on your subject's face to ensure proper exposure.
B. Using Low Key Lighting (More Control, Requires Practice)
* Ambient Light (Controlled): This involves using very little ambient light and carefully controlling the light source hitting the subject.
* The Room: Ideally, work in a dark room. Turn off all the lights or cover windows to minimize ambient light.
* Lighting:
* One or Two Lights: You'll typically use one or two lights. One as a main light (key light) and optionally a second as a fill light (very low power).
* Light Placement: Position the light to highlight the subject's features. Experiment with different angles and distances.
* Flags & Snoots: Use flags and snoots (conical attachments for lights) to precisely control the light beam and prevent it from spilling onto the background.
* Camera Settings:
* Metering: Use spot metering on the subject's face.
* Underexposure: Intentionally underexpose the shot to darken the background. You can recover detail in the subject during post-processing.
* Aperture: A slightly smaller aperture (e.g., f/5.6 - f/8) might be necessary to ensure the subject is sharp, especially if they are moving.
C. Using Speedlights Off-Camera (Portable and Versatile)
* Equipment: Off-camera speedlight(s), wireless triggers, light stand(s), light modifier(s) (softbox, umbrella).
* Technique: Similar to using strobes, but with more portability.
* Power Control: Speedlights usually have less power than studio strobes, so you may need to be closer to your subject or use multiple speedlights.
* TTL vs. Manual: You can use TTL (Through-The-Lens) metering for initial setup, but manual mode is generally preferred for consistent results. Adjust the power of the speedlight manually to achieve the desired exposure on the subject and a dark background.
D. Using Natural Light (Most Challenging, Requires Specific Conditions)
* Location: Look for a location with deep shade, like a covered porch, a doorway facing away from direct sunlight, or a shaded alleyway.
* Background: Ensure the background is dark and far enough away from the subject.
* Technique:
* Positioning: Position the subject so that they are lit by soft, indirect light.
* Metering: Meter off the subject's face and underexpose slightly.
* Post-Processing: You'll likely need to darken the background further in post-processing.
III. Camera Settings Considerations (General)
* Shooting Mode: Manual mode is highly recommended for maximum control. Aperture Priority (Av or A) can work if you are careful with your metering.
* Metering Mode: Spot metering is best for accurate exposure of the subject's face.
* White Balance: Set the white balance according to your light source (e.g., flash, daylight, tungsten). You can also shoot in RAW and adjust the white balance in post-processing.
* Focus Mode: Use single-point autofocus to ensure sharp focus on the subject's eyes.
IV. Post-Processing (Essential!)
Post-processing is almost always necessary to refine your black background portraits.
* Software: Adobe Lightroom, Adobe Photoshop, Capture One, or similar photo editing software.
* Key Adjustments:
* Exposure/Brightness: Adjust to properly expose the subject.
* Contrast: Increase contrast to make the subject stand out against the background.
* Blacks/Shadows: Lower the blacks and shadows to darken the background further. Be careful not to crush detail in the subject's dark areas.
* Highlights/Whites: Adjust the highlights and whites to bring out detail in the subject's lighter areas.
* Dodging and Burning: Use dodging (lightening) and burning (darkening) tools to refine the light and shadows on the subject's face.
* Spot Removal: Remove any dust spots or distractions on the background.
* Gradient Filter/Radial Filter: Use these to darken the background in specific areas.
V. Tips and Tricks
* Distance is Key: The further your subject is from the background, the easier it is to achieve a black background.
* Experiment with Lighting: Try different lighting angles, modifiers, and power levels to find the look you like.
* Watch for Reflections: Be mindful of reflections on the subject's skin, clothing, or eyes.
* Test Shots: Take test shots frequently to check your exposure and lighting. Adjust your settings as needed.
* RAW Format: Shooting in RAW format gives you more flexibility in post-processing.
* Practice Makes Perfect: Don't be discouraged if your first attempts aren't perfect. Keep practicing, and you'll improve with time.
* Hair Light: A subtle hair light can add separation and dimension, especially if your subject has dark hair. Position it behind and slightly to the side of the subject.
* Black Clothing: If your subject is wearing black clothing, be extra careful with your lighting to avoid losing detail in the clothing.
VI. Common Mistakes to Avoid
* Not enough distance between the subject and background.
* Light spilling onto the background.
* Under- or over-exposing the subject.
* Using too much ambient light.
* Forgetting to post-process.
* Crushing the blacks too much in post-processing, losing detail in shadows.
* Using too harsh light, creating unflattering shadows.
By following these steps and practicing, you can create stunning portraits with a black background that highlight your subject and create a dramatic and professional look. Good luck!
