Photography three kinds of light

That is, that position of the main lamp form an angle of 45 degrees with the front of the main body,

Auxiliary light 75 degrees,

Add a light to the head.

The function of the main lamp is to depict the image and spirit of the characters.

The auxiliary lamp lightens the shadow of the shape of the main lamp,

Rich in layers,

Lights separate people from the background,

To enhance the three-dimensional sense.

Because of the long-term use of light to shoot portraits all over China,

So people call this form of light use the use of traditional light.

Triangular lights (also known as V-shaped lights)

Triangular light is the most commonly used form of tidal light in photo studios in recent years.

This kind of lamp is developed from the eight-character lamp.

In the past, wedding dresses and photo shoots were all taken with eight-character lights.

That is, two lamps illuminate the object at the same distance at an angle of 45 degrees,

The brightness is also completely equal,

light ratio

Usually 1: 1,

The 45-degree angle of that double lamp forms an illumination area with a 90-degree angle,

Formed a figure-of-eight light,

Referred to as double lamp balance.

Angle greater than 90 degree or less,

The angle has changed,

The light receiving surface also changes,

This is not a light number.

A lamp

Before,

A lamp is in the back,

Not to mention the eight-character light.

Eight-character light can also be divided into big eight-character and small eight-character

This light is mainly planar illumination,

Characterized by bright, bright, bright, noble and warm,

It was once recognized as the most beautiful light source by portrait photographers.

But this form of light is widely used,

People always find it unbearable,

Lack of personality.

Later, some photographers introduced advertising photography to wedding portrait photography.

On the premise of the original eight-character lamp,

A lamp was added to the ground,

It's also flat lighting,

I found the characters' eyes particularly bright.

Shiny, eye-catching,

The shadow between two people has disappeared,

The shadow of the neck disappeared,

It looks cleaner and brighter,

This movie is more beautiful,

Eyes are more prominent,

This is triangle lighting.

But some people think that this kind of

Light beat

The characters are fatter,

This is a failure to master the skills and methods of this light source.

1.

Triangular light entry

Role modeling

In fact, it belongs to the category of great flat light.

It is made up of Three Lamps District.

Soft light lamp

Composition,

Two soft lights are placed on the left and right sides of the camera.

The soft light is placed in front of the object,

The target is in the triangle light area,

Triangle light for short.

2.

Location of light:

Put the light down.

camera bellows

The center (that is, the center position of the light source) is opposite to the hair position of the subject.

The low part of that flexible box faces the face of the person,

The upper part faces the background behind the characters,

Because the center of the light emitted by the soft box is the brightest,

four

Bian Jiang

Darker,

Generally, the center differs from the edge by 0.8 to 1,

Therefore,

The brightest light source illuminates the hair,

Because of the absorption of hair,

Increase exposure and appear transparent,

Strong sense of hierarchy.

The face is reflective,

With a relatively weak light source,

Balance the light of face and hair,

The upper part of the soft box glows on the background,

Enhance the level and brightness of the background.

In general,

Triangle lights don't need to emit lights,

In order to make the picture more natural and realistic.

When the position of the lamp is fixed,

The other lamp presses the same height at the same time,

Illuminate the theme from the other side.

floor lamp

The application of,

Not very bright,

Not too dark,

Too bright will make the outline of the face and neck disappear.

If it is too dark, the meaning of triangular light will be lost.

I can't feel that transparency and brightness.

Therefore,

The intensity of the three lamp areas is the same,

The distance between the lamp and the main body is the same.

3.

Before using triangular light,

The intensity of each lamp must be measured with a sidelight meter to reach the same level.

When measuring an object irradiated by a lamp

Aperture value

Do it.

During the filming,

Shorten the distance,

The corresponding aperture is reduced,

The distance increases,

Open the aperture.

This method,

There are few opportunities for lighting errors when shooting.
