Inside the booth
Place a window catchlight without turning the eyes toward glare
Use the window position to create a visible eye reflection while preserving comfortable gaze.
A catchlight helps show the direction of a large light source in the eye. It should be a small, controlled reflection; if the subject squints or glasses flare, change the angle rather than asking them to stare into bright light.
Set a comfortable angle
Place the subject near a window and turn their face slightly toward it, not directly into the sun. Ask them to look just beside the camera. Check that the eyes remain relaxed and the window reflection appears naturally.
Adjust the camera
Move the camera a little higher or lower to shift the reflection within the eye. If glasses catch a large white patch, change the subject or camera angle and keep the window out of the lens reflection.
Review both eyes
Take a test and zoom in on the saved image. If one eye has no catchlight or the reflection covers the iris, make a small angle change. Stop if the person is uncomfortable; an expressive portrait matters more than matching catchlights.
