1. Gear You'll Need:
* Camera: A DSLR or mirrorless camera offers the most control. You *can* use a phone with an external flash, but results will be limited.
* Flash: An external flash (speedlight) is essential. The built-in flash on your camera usually produces harsh, unflattering light. Look for a flash that supports TTL (Through-The-Lens) metering for automatic exposure.
* Flash Modifier (Essential): This diffuses and softens the flash's light. Consider:
* Softbox: Creates a large, soft light source. Good for studio-quality results on location, but can be bulky.
* Umbrella (Shoot-Through or Reflective): More portable than a softbox. Shoot-through umbrellas soften light, while reflective umbrellas bounce the light back.
* Speedlight Diffuser (e.g., Gary Fong Lightsphere, Rogue FlashBender): Compact and convenient, but may not soften the light as much as larger modifiers. Good for subtle fill.
* Bounce Flash (built-in or external flash, pointed at wall/ceiling): If you're indoors with light colored walls/ceilings, bounce flash can create natural-looking light.
* Light Stand (Optional, but Recommended): For holding your flash and modifier off-camera.
* Wireless Flash Trigger (Optional, but Highly Recommended): Allows you to control the flash remotely, giving you more freedom in placement. Many flashes have built-in optical triggers, but radio triggers are more reliable, especially outdoors.
* Tripod (Optional, but Recommended): Helpful for keeping your camera steady, especially with longer exposures.
2. Camera Settings:
* Mode: Manual (M) is best for complete control. Aperture Priority (Av or A) can work, but you'll need to compensate with flash exposure compensation.
* Aperture: Choose an aperture based on your desired depth of field.
* Wider Aperture (e.g., f/1.8, f/2.8, f/4): Creates a shallow depth of field, blurring the background and isolating your subject. Use if you want a dreamy, focused-on-the-subject look.
* Narrower Aperture (e.g., f/5.6, f/8, f/11): Creates a greater depth of field, keeping more of the scene in focus. Useful if you want a sharp background or are shooting a group.
* Shutter Speed: This controls the ambient light (background).
* Start at 1/60th or 1/125th of a second. Adjust from there. Faster shutter speeds darken the background; slower shutter speeds brighten it. Don't go *too* slow, or you'll introduce camera shake.
* Important: Know your camera's flash sync speed. This is the fastest shutter speed you can use with flash. Typically, it's 1/200th or 1/250th of a second. Using a faster speed can result in a dark band in your image. High-speed sync (HSS) can be used, but reduces flash power.
* ISO: Keep the ISO as low as possible (e.g., ISO 100, ISO 200) to minimize noise. Increase only if necessary to brighten the background without sacrificing flash power.
* White Balance: Set it to Flash or Auto. Adjust in post-processing if needed.
* Focus Mode: Use single-point autofocus and focus on your subject's eyes.
3. Flash Settings:
* TTL (Through-The-Lens) Metering: Start with TTL mode. The flash will automatically adjust its power based on the light reflected back from your subject.
* Flash Exposure Compensation (FEC): This is *crucial* for fine-tuning the flash power. After taking a test shot in TTL mode, use FEC to adjust the flash's output:
* + FEC: Increases flash power (brightens your subject).
* - FEC: Decreases flash power (dims your subject).
* Manual Mode (Advanced): Once you're comfortable with TTL, try manual mode. This gives you complete control over flash power. Start with a low power setting (e.g., 1/16, 1/32) and increase it gradually until you get the desired exposure.
* Zoom Head: Adjust the zoom head of your flash to match your lens' focal length. A wider zoom setting will spread the light out, while a narrower setting will focus it.
4. Flash Placement Techniques:
* Off-Camera Flash (Recommended):
* Side Lighting: Position the flash to the side of your subject (around 45 degrees). This creates shadows and adds dimension.
* Feathering: Aim the flash *slightly away* from your subject. This softens the light and reduces harsh shadows.
* Rembrandt Lighting: Place the flash slightly behind and to the side of your subject, creating a small triangle of light on their cheek.
* On-Camera Flash (Less Ideal, but Sometimes Necessary):
* Bounce Flash: Aim the flash at a ceiling or wall to diffuse the light.
* Diffuser: Use a diffuser on your flash to soften the light.
5. Steps for Taking a Night Portrait:
1. Scout Your Location: Look for interesting backgrounds and light sources (streetlights, signs) to incorporate into your composition.
2. Set Your Camera: Choose your aperture, shutter speed, and ISO based on the ambient light and your desired depth of field.
3. Position Your Subject: Consider the background and available light.
4. Set Up Your Flash: Attach your modifier and position the flash.
5. Take a Test Shot: Use TTL mode and adjust FEC as needed.
6. Fine-Tune Your Settings: Make small adjustments to your camera and flash settings until you get the desired exposure and look. Experiment with different flash positions and modifiers.
7. Focus and Shoot: Focus on your subject's eyes and take the shot.
8. Review and Adjust: Check the image on your camera's LCD screen and make any necessary adjustments.
Tips and Tricks:
* Start Simple: Don't try to do too much at once. Begin with a single flash and a simple modifier.
* Practice: The more you practice, the better you'll become at understanding how flash works.
* Pay Attention to Shadows: Look at the shadows on your subject's face. Are they too harsh? Are they in the right place?
* Watch for Overexposure: Be careful not to overexpose your subject. Use the histogram on your camera to check your exposure.
* Consider Color Temperature: Mix flash with ambient light. Adding a CTO (color temperature orange) gel to your flash can match warmer ambient light sources (streetlights, etc.).
* Post-Processing: You can further enhance your images in post-processing software like Adobe Lightroom or Photoshop. Adjust exposure, contrast, white balance, and sharpness.
* Engage with Your Subject: A relaxed and comfortable subject will always look better in a portrait. Talk to them, make them laugh, and give them direction.
* Use a Reflector: A reflector can bounce light back onto your subject, filling in shadows and adding brightness. It can be used to augment the light from your flash or from an existing light source.
* Back Button Focus: Separating focus from the shutter button by using the back button to focus can be helpful, especially in low-light conditions.
* Shoot in RAW: Capturing images in RAW format provides more flexibility during post-processing.
Common Mistakes to Avoid:
* Harsh, Direct Flash: This creates unflattering shadows and a flat, artificial look. Always use a modifier or bounce the flash.
* Overpowering the Flash: The flash should complement the ambient light, not overpower it.
* Forgetting to Adjust FEC: Flash exposure compensation is essential for fine-tuning the flash power.
* Using Too High an ISO: This can introduce noise into your images.
* Ignoring the Background: The background is just as important as the subject. Choose a background that complements your subject and doesn't distract from the portrait.
By following these tips and practicing regularly, you can create stunning night portraits with flash. Good luck!
