Backlight is a view or aspect of things when you look at them from the opposite side where they are illuminated “when a person stands up against the light, only lets them see their silhouette”. That is, when we take a photograph having the light behind the subject and facing the camera. Backlight with highlight light. It consists of taking advantage of the light from the background and, in addition, illuminate the subject ahead to enhance the detail that otherwise we would only get shadows. With the sun behind the subject, it can be illuminated with a flash or a lamp in front of the subject, to achieve a more uniform illumination.
