TIP #24: Catch the light.
“Catch lights” are white highlights in the eye, created by a reflection of a light source (like the sun, window light, a lamp, etc). This highlight adds depth and dimension to the eye, and gives the eyes life in a portrait or snapshot. Adding a catch light can help draw attention to the subject’s eyes.
Pay attention to the light and to your subject’s eyes and try to catch that light. This is done by simply paying attention to angles, reflections, and positioning yourself so that you are able to see and capture that light. It will make your image go from ordinary to extraordinary.
