In studio portrait photography, what kind of figure are triangular light' high and low light' and butterfly light' Rembrandt' suitable for respectively? What are the advantages and disadvantages?

What a big question you asked! Butterfly lighting, commonly known as butterfly lamp, is a special way to use light in portrait photography.

Butterfly lamp, in a sense, is an inclined ceiling lamp, a way of using light in front light or in front light.

The method of arranging lights is more suitable for westerners and people with clear bones.

The usual way of butterfly light distribution is that the main light source is above the optical axis of the lens, that is, right in front of the subject's face. It projects a butterfly-shaped shadow under the nose, which brings a certain sense of hierarchy to the face.

Butterfly light is mostly used to represent women. After this light hits the model's face, the most obvious sign is that it will produce a butterfly-like shadow under the nose.

Strong light and weak light (free light)

Lighting consists of main lamp and auxiliary lamp. The main light is projected downward at an angle of about 30-45 degrees, and the optical center should shine on the eyebrows or foreheads of the characters. The sub-lamp shines on the face of the person directly below the main lamp, and the illumination index of the sub-lamp is about 1-2 lower than that of the main lamp. This method of light distribution is called high and low light because it is placed one on top of the other.

Characteristics of high and low light: it is a very flexible light, which can freely control the tone level of human face (it can form the tone effect of plane light, front light and butterfly light), so it is called free light, which is the most commonly used light distribution for wedding photography and beauty photography.

Requirements for high and low light distribution:

(1), the main light can be hard light or soft light only. The auxiliary light should be kept on a vertical plane directly below the main light, and together with the main light, the tone level of the face can be controlled at will.

(2) On the other side of the high and low light, a reflector should be used to fill the light, and at the same time, contour light, background light and skylight should be used together.

(3) How to use high and low light in wedding photography;

A, in wedding photography, if two people are facing the camera or their faces are opposite, high and low lights can form the effect of two lamps' plane light, so as to illuminate the figure with positive light level. Using reflectors on both sides of the figure will enhance the plane light effect.

B, when two people's faces are facing one side, guide their faces in the direction of high and low light, let the high and low light freely control the color of their faces, and then use the reflector to fill the light on the other side of the character.

C. When two people face to one side, the lady's face can face to the high and low light side, while the man's face can be shaped with a sidelight single lamp, or a reflector can fill the light for the man. If you want to make both sides bright, you can also directly illuminate the characters with high and low light to form a plane light effect.

Triangle lamp (Sanqi lamp)

The purpose of light distribution is to make the main light form an inverted triangular light block under the eyelid on one side of the nose. Triangular light makes the light-receiving surface of a character's face larger than the backlight surface, so it is called Sanqi light.

Sanqi light is divided into big Sanqi light and small Sanqi light. When the lower end of the inverted triangular light block is aligned with the nose or extends through the nose to the corners of the mouth of the person, it is called the big Sanqi light, which is also called Rembrandt light. It is a kind of light commonly used by the Dutch painter Rembrandt to shape characters in his paintings, and it is also the most stereoscopic light. When the light is distributed, the main light projects a 45-degree angle to the eyebrows of the characters. When the lower end of the inverted triangular lamp block is higher than the nose, it is called a small Sanqi lamp. Small Sanqi light forms more shadows than big Sanqi light, and the projection angle of the main light on the eyebrows of the characters is less than 45 degrees.

Triangular light distribution requirements:

(1), the main light can be hard light or soft light. Strong light can make the tone clear. Soft light can make the tone soft and rich.

(2) The main light has no fixed light level, which is based on the purpose of making an inverted triangular light block. When the inverted triangular light block is facing the camera, people's faces will be very thin and have a strong three-dimensional sense.

(3) Triangular light should be equipped with auxiliary light or reflector, and the light ratio of main and auxiliary light should be controlled at around 1: 8. (4), triangle light can use background light, contour light, but not skylight.

Triangular light is also called Rembrandt light.

The left and right light clips are generally used for dark tone shooting. The light clip is mainly played on the side of the figure, which assists the reflector to realize the needed light, and there will be an outline light behind the figure. Suitable for shooting some films that pursue artistic conception, but require high contrast and control of main light and auxiliary light, which is not easy to grasp! 、

I'm also a photographer. I used to work in the studio, but now I am at home, haha ~ ~ ~ Good teachers are hard to find! qq54472 1874
