Understanding the Desired Look
* Soft Light: The goal is to avoid harsh shadows and create smooth transitions between light and dark areas.
* Wrap-Around Light: The light should gently curve around the subject's features, revealing the form without emphasizing imperfections.
* Catchlights: A clear catchlight in the eyes is crucial to bring the subject to life.
* Controlled Shadows: The shadows should be present to define the face but not be overly dark or distracting.
Equipment You'll Need
1. One Light Source: A strobe (speedlight or studio strobe) or a constant light (LED panel or even a strong lamp). For beginners, a speedlight is often a good starting point.
2. Large Softbox or Umbrella: This is *essential* for creating the soft light you want. The larger the light modifier, the softer the light. A 36" or larger softbox or a parabolic umbrella would be ideal. If you don't have these, you can bounce the light off a large white surface (wall or foam core).
3. Light Stand: To position your light.
4. Reflector (White or Silver): A reflector is your friend. It bounces some of the light from your main light back onto the subject's shadow side, filling in the shadows and adding another catchlight in the eyes.
5. Camera and Lens: A portrait lens (50mm, 85mm, or a zoom in that range) is recommended.
6. Optional: Background: A simple, neutral background (white, gray, or black) works best.
Setup and Shooting
1. Positioning the Subject: Place your subject in front of your background. The distance to the background will affect the appearance, but you usually want the subject far enough away to avoid shadows.
2. Light Placement: This is key.
* 45-Degree Angle: Start by placing your light at roughly a 45-degree angle to your subject's face (either side).
* Height: The height of the light is also crucial. Position it slightly *above* the subject's eye level. This will create flattering shadows under the chin and nose.
* Distance: The distance of the light from your subject controls the light intensity. Start relatively close to the subject and move it further away to lower the intensity.
* Softbox/Umbrella Aim: Aim the center of the softbox or umbrella at the subject's face.
3. Reflector Placement:
* Position the reflector opposite the light source, close to the subject. You might need to experiment with the angle to get the best fill light.
* Angle: Angle the reflector to bounce the light back into the shadows on the subject's face. Watch how the shadows soften and how the second catchlight appears in the eye.
* Distance: Adjust the distance of the reflector from the subject to control the amount of fill light. Closer = more fill.
4. Camera Settings:
* Aperture: Aim for a shallow depth of field (e.g., f/2.8, f/4) to blur the background and draw attention to the subject.
* ISO: Keep your ISO as low as possible (ideally ISO 100 or 200) to minimize noise.
* Shutter Speed: Adjust your shutter speed to get the correct exposure. For strobes, the maximum sync speed of your camera will be a limiting factor (usually 1/200th or 1/250th of a second).
* Power: Start with a low power on your light. Take a test shot, and increase the power until your meter (or your camera's histogram) shows a good exposure. For constant lights, you will control the intensity via aperture and ISO.
* Metering Mode: Use spot metering mode and meter on the subject's face, or use manual mode.
5. Taking the Shot and Adjusting:
* Take a test shot and carefully examine the image.
* Shadows: Are the shadows too dark? Adjust the reflector's position or angle to bounce more light into the shadows. Or move the light farther away.
* Highlights: Are there any blown-out highlights (areas that are completely white with no detail)? Reduce the light's power.
* Catchlights: Are the catchlights visible and pleasing? If not, adjust the height and angle of the light or the reflector.
* Subject's Posing: Make sure the subject is comfortable and relaxed. Slight changes in head position can dramatically change the light and shadows on the face.
Tips and Troubleshooting
* Start Simple: Don't try to overcomplicate the setup. Start with the basics and gradually add complexity as you become more comfortable.
* Practice: Practice with a friend or family member who is willing to be your model.
* Observe: Study portraits you admire and try to identify how the light is being used.
* Diffuse the Light More: If the light is still too harsh, add a diffusion panel or scrim in front of the softbox or umbrella. You can also bounce the light off a larger surface.
* White Balance: Set your white balance correctly to avoid color casts. You can also adjust the white balance in post-processing.
* Post-Processing: Use software like Adobe Lightroom or Photoshop to fine-tune your images. You can adjust exposure, contrast, and color, and remove blemishes.
Example Setup
Imagine:
* Subject: Standing in front of a gray seamless paper background.
* Light: A speedlight with a 36" softbox, placed at a 45-degree angle to the subject's left, and slightly above eye level.
* Reflector: A white reflector, held by an assistant on the subject's right, angled to bounce light back into the shadow side of the face.
Common Mistakes to Avoid
* Too much power: Overpowering your light is a common mistake, especially with speedlights.
* Too small a light source: A small light source will create hard shadows.
* Ignoring the reflector: The reflector is crucial for filling in shadows and creating a more balanced image.
* Poor posing: The subject's pose can dramatically affect the way the light falls on the face.
By following these steps, experimenting with different positions, and practicing, you'll be well on your way to creating beautiful one-light portraits! Good luck!
