The Core Idea: Look for Highlights and Shadows
The light in a portrait isn't just about brightness. It's about the relationship between the bright (highlights) and the dark (shadows). This contrast is what shapes the face and gives it dimension.
Quick Tip: The Eyeball Test (Literally)
1. Look at Their Eyes: The eyes are the windows to the soul, and also the windows to the light.
* Catchlights: Are there bright reflections (catchlights) in their eyes? The position and shape of these catchlights tell you where the light is coming from.
* Shadows on the face: are shadows from the nose or brow making part of the face darker.
2. Turn Your Subject Slowly: Have the person gently rotate their face left and right. Watch how the light changes. Notice how the highlights and shadows shift. This will help you understand how the light interacts with their features.
What to Look For (Good Light Qualities):
* Soft Light: Look for soft, diffused light. This is light that isn't harsh and doesn't create deep, dark shadows. Overcast days, open shade (shade that's not directly under something like a tree), or light coming through a sheer curtain are good examples. Soft light is very flattering.
* Directional Light: Light that is coming from a defined direction will help to sculpt the face. Position your subject with the light coming from one side so that you can define one side of the face.
* Avoid Direct, Harsh Sunlight: This creates squinting, unflattering shadows, and blown-out highlights. You can use it, but it's much harder to manage as a beginner.
* Even Light: Even light can be a good choice in some situations, though may make the face look a bit flat. You can add interest with posing, but generally you should avoid.
Practical Examples:
* Indoors:
* Near a Window: Have your subject stand near a window with the light coming in from the side. Pay attention to the catchlights in their eyes.
* Facing the Window: Facing the window will give you fairly even light, but maybe a bit flat. Rotate slightly to the side of the window to add interest with directional lighting.
* Outdoors:
* Open Shade: Find a shady spot that's still open to the sky, like under a large awning, or on the north-facing side of a building.
* Overcast Day: Overcast days are your friend! The clouds act as a giant softbox, diffusing the light.
The "No-No's":
* Backlighting (Directly): Having the sun directly behind your subject *can* create a cool silhouette, but it's challenging for beginners. You'll likely end up with a very dark face. (Though, you can use reflectors to bounce light back onto the face in this situation.)
* Harsh Shadows Across the Face: Look for shadows that are distracting or unflattering, like those caused by strong sunlight filtering through tree leaves.
The Exercise:
Practice! Find a friend or family member. For the next week, take 5 minutes a day to just observe the light on their face in different locations. Ask yourself:
* Where is the light coming from?
* What kind of shadows is it creating?
* Is it flattering or unflattering?
Key takeaway: Seeing the light for portraits is about understanding how highlights and shadows shape the face. By observing these, you can choose the most flattering light for your subject. The eyeball test is a great, simple way to start.
