There are four main roles of lighting in imagery:

1.Exposure effect

Lighting enables the film film to obtain accurate exposure, so that the film can get a normal negative density after processing, and enhance the light sensitivity effect of the film, which is also the most basic role of lighting. Under the premise that the existing natural light source in the scene is insufficient, it is necessary to artificially enhance the lighting in the scene, which can enhance the light sensitivity of the film and improve the quality of the picture.

2.Modeling effect

Lighting allows the picture in the two-dimensional space to appropriately present the texture, three-dimensionality, space and other artistic effects of the subject according to the requirements of photographic art creation. Lighting with strong contrast between light and dark can create a tough image of men; soft lighting can create a feminine temperament.

3.Composition effect

The light and dark effects produced by lighting can highlight the subject, balance the composition of the picture, outline the plane and sculptural space, and give the composition a formal beauty.

4.Dramatic effect

Lighting makes the subjects in the picture have a dramatic effect, can describe and express the environment, makes the subjects in the picture have a sense of aesthetics, and makes the characters in the picture have a dramatic effect.

Lighting processing can be divided into indoor lighting and outdoor lighting:

(1)Exterior lighting

In order to better express the theme of the film, outdoor lighting is often shot on a sunny day with sufficient sunlight and "transparent" light.

(2)Interior lighting

The indoor lighting is mainly based on high-wattage spotlight lighting, creating and rendering a warm, golden lighting effect. It can also make the character's body and face have a clear contrast between yin and yang, and the modeling effect is strong.

The five most common types of photographic lights

1. Flat lighting

The light hits the subject at the same angle as the camera lens. Flat lighting fills in shadows and creates a realistic look. Typically used for headshots and editorial shots.

2. Butterfly lights

Also known as a type of "supreme" photography lighting, butterfly lighting comes from the front and above the subject's face. This lighting pattern casts a butterfly-shaped shadow under the subject's nose.

Reflectors placed under the subject's face produce a more flattering flip lighting pattern.

3. Cycle lighting

When using cycle lighting, objects are illuminated at an angle from above. The lighting pattern is characterized by diagonal shadows falling under and to the sides of the subject's nose.

Cycle lighting can still fill in most of the shadows on the subject's face, but it starts to create shapes and add some drama to the portrait.

4. Rembrandt lighting

Similar to cycle lighting, Rembrandt lighting involves lighting a subject at an angle from above the face, but this time at a stronger angle. The triangle of light beneath one eye is one of the defining features of this lighting pattern.

The face is mostly in shadow, giving it a dramatic and edgy look.

5.Split lighting

Split lighting comes directly from the subject's face and is the most striking of the five types of photography lighting discussed here. Half his face fell into shadow.

Split lighting is often used for sports portraits because it brings a lot of definition.
