* Is flattering: Emphasizes the subject's best features and minimizes flaws.
* Is interesting: Adds depth, dimension, and mood to the image.
* Is controllable: Allows you to manipulate the light to achieve your desired look.
Understanding the Qualities of Light
* Intensity: Refers to how bright the light is.
* Harsh light (e.g., direct midday sun) creates strong shadows, high contrast, and can be unflattering.
* Soft light (e.g., overcast day, open shade) is diffused, gentle, and creates smooth transitions between light and shadow.
* Direction: Refers to where the light is coming from in relation to the subject.
* Front lighting: Light source is in front of the subject. Can be flattering but can also be flat and boring.
* Side lighting: Light source is to the side of the subject. Creates dimension, shadows, and can emphasize texture.
* Back lighting: Light source is behind the subject. Creates a silhouette or rim light, adding a dramatic effect.
* Top lighting: Light source is above the subject. Can create unflattering shadows under the eyes and nose.
* Bottom lighting: Light source is below the subject. Often creates a spooky or unnatural look.
* Color: Refers to the color temperature of the light, measured in Kelvin (K).
* Warm light (e.g., golden hour) has a lower Kelvin temperature and appears more orange or yellow.
* Cool light (e.g., shade, overcast sky) has a higher Kelvin temperature and appears more blue.
* Quality: Refers to whether the light is hard or soft. Hard light is more directional and creates sharp shadows. Soft light is diffused and creates gentle shadows.
How to Use Light for Beautiful Portraits:
1. Identify and Use Natural Light:
* Open Shade: Look for areas where the sun is blocked by a building or tree, but the area is still bright. This provides soft, diffused light that's very flattering.
* Golden Hour: The hour after sunrise and the hour before sunset provide warm, soft, and beautiful light.
* Overcast Days: Overcast skies act as a giant softbox, providing even, diffused light with minimal shadows.
2. Control Natural Light:
* Reflectors: Use reflectors (white, silver, gold) to bounce light back onto the subject, filling in shadows and adding a catchlight to the eyes. White reflectors create a neutral light. Silver provides a brighter, more specular light. Gold adds warmth.
* Diffusers: Use diffusers to soften harsh sunlight. These can be translucent scrims or even sheer curtains.
* Positioning: Move your subject to a location where the light is more flattering. For example, rotate the subject to get side-lighting instead of front-lighting.
3. Work with Artificial Light (Studio or Speedlights):
* Softboxes: Attach softboxes to your lights to create soft, diffused light, similar to open shade.
* Umbrellas: Umbrellas (shoot-through or reflective) also soften light.
* Bare Bulb: Can provide more contrast and specular highlights.
* Light Modifiers: Use grids, snoots, and barn doors to control the direction and shape of the light.
* Power Control: Learn to adjust the power of your lights to balance the light with ambient light or to create different effects.
4. Specific Lighting Techniques for Portraits:
* Butterfly Lighting: Light source is directly above and slightly in front of the subject. Creates a small butterfly-shaped shadow under the nose.
* Loop Lighting: Similar to butterfly lighting, but the light is slightly to the side, creating a small loop-shaped shadow on the cheek.
* Rembrandt Lighting: Light creates a triangle of light on the cheek opposite the light source.
* Split Lighting: Light is aimed from the side, illuminating only half of the face.
* Rim Lighting: Subject is lit from behind, creating a bright outline around the edges.
5. Tips for Finding and Creating Good Light:
* Pay Attention to Shadows: Where are the shadows falling? Are they harsh or soft? Do they enhance the subject's features or detract from them?
* Look for Catchlights: Catchlights (small highlights in the eyes) add life and sparkle to a portrait.
* Consider the Background: The background should complement the subject, not distract from them. The light on the background can also affect the overall mood of the image.
* Experiment: Don't be afraid to try different lighting techniques and angles to see what works best for your subject.
* Practice: The more you practice, the better you'll become at seeing and manipulating light.
* Observe: Study portraits by other photographers and analyze how they used light.
In summary, "good light" is about understanding how light interacts with your subject and using it to create a flattering, interesting, and visually appealing image. It involves both identifying existing light and manipulating it to achieve your desired results.
