What is backlight and smooth light in photography?

Also called positive light and peaceful light. Light shines from the front of the subject, which is characterized by high brightness, flat image and good color reproduction, but the light is relatively flat, so it is difficult to show three-dimensional sense.

2. Backlighting

Also known as "backlight". The light comes from the back or oblique back of the subject, which is characterized by drawing a beautiful outline for the subject, distinguishing the characters from the background, and showing a strong sense of space.

Positive and negative light: the light source is placed directly behind the subject, and sometimes the light source, the subject and the lens are almost in a straight line.

Side backlight: the light source is placed behind the subject and forms a certain angle with the shooting axis. In shooting, the light source generally does not appear in the picture.

High backlight: sometimes called "top backlight", the light source is above the back or side of the subject, and generally forms a wide light bar at the edge of the subject.

Extended data

Backlight shooting is just the opposite of smooth shooting. The shadow area of the shot picture is large, so the tone is dark, and the subject can show obvious light and dark relationship in the picture. When matched with other light, the light behind the subject will have a strong light ratio with other light.

If we want to clearly show the key points of shooting and ensure the correct expression of the texture and shadow level of the main part, then we must control the exposure and remove the texture and shadow level of the secondary part.
