Rim lighting, also known as edge lighting, is a method of lighting a subject by using off-camera flash. The technique is used to separate a subject from the background by using a rim or strip of light around the edges of the subject.

How is it done?

A rim light is placed behind a subject that exposes the outline or rim of the subject with light. This lighting highlights the contours of a subject and creates a dramatic and mysterious effect. Rim lights can be used in a variety of ways.

Below are the photos I took of Poppy, these are the ones that worked with the light. It took many tries to get the lighting correct but we got it in the end to outline her side profile, hair, chin and slightly her body.
