Tip: Look at the catchlights in the eyes.
Why this works:
* Easy to Spot: The catchlights (the small reflections of the light source) are the easiest thing to identify in a portrait. They are bright and concentrated.
* Tells You Source and Direction: The catchlights reveal the light's position relative to your subject.
* High: Light is coming from above.
* Low: Light is coming from below.
* Left/Right: Light is coming from that side.
* Size: The *size* of the catchlight (assuming its a single catchlight) tells you a bit about how *soft* or *hard* the light is (larger = softer, smaller = harder).
* Reveals Issues: Missing catchlights suggest the light source isn't hitting the eyes (perhaps the subject is looking down or is in too much shadow).
How to Use It:
1. Before You Shoot, Observe: Before you even pick up your camera, look at your subject's eyes. Where are the catchlights?
2. Assess the Light:
* Direction: Is the light coming from a flattering angle? Light slightly to the side is generally good.
* Intensity: Is the light creating nice contrast on the face, or is it too harsh (strong, small catchlights and deep shadows) or too flat (very large, diffused catchlights and little shadow)?
3. Make Adjustments (If Possible):
* Subject Position: Have your subject turn their face slightly to catch the light better. Ask them to look up or down slightly to change the position of the catchlights.
* Your Position: Move yourself to change the angle.
* Light Source (If Possible): If you have control over the light (e.g., indoors), move a lamp or adjust a reflector.
4. Pay Attention to the Catchlights During Shooting: Continuously check the catchlights on the back of your camera screen as you shoot and adjust accordingly.
Example Scenarios:
* Outdoor Shade: If the catchlights are large and soft, and come from slightly above, you're probably in good, diffused light. This is generally flattering.
* Direct Sunlight: Small, intense catchlights directly in the eyes are usually harsh. Try to find some shade. If not possible, have the subject turn slightly away from the sun or use a reflector to soften the shadows.
* Indoor, Window Light: The catchlights will be shaped like the window. Position your subject so the window light illuminates their face at a pleasing angle.
* No Catchlights: This means there is likely not enough light reaching your subject's eyes. You can solve this by repositioning or adding a light source.
Key Takeaways:
* Start Simple: Focus on the catchlights as your primary guide.
* Experiment: Practice observing catchlights in different lighting situations.
* Refine Later: As you gain experience, you can start to analyze other aspects of the light, like shadow patterns and color temperature.
This tip is a starting point. Practice is key to developing your "eye" for light. Good luck!
