What does the term "backlight" refer to in lighting design?

The term "backlight" in lighting design refers to light that is directed behind a subject. This technique is commonly used to create a sense of depth, separation, and focus on the subject being illuminated while enhancing the overall visual composition. Backlighting often creates an outline or halo effect around the subject, which can add interest and dimension to the scene. It is particularly useful in photography and cinematography to highlight textures and shapes, giving the viewer a clearer perception of the subject's form against the background. This contrasts with the other options, which refer to lighting positions that do not create the distinctive effects associated with backlighting.
