How to shoot advertising photography well

Photography is a creative work, which often reflects the photographer's personality and style, and is also related to a work.

Success or failure is at stake.

Let me talk about six factors that describe light: luminosity, light quality, light level, light type, light ratio and light color.

* * I. Brightness * *

Brightness is the most basic factor of light, and it is the general name of the luminous intensity of light source and the brightness of light on the surface of an object. Photometric sum

Exposure is directly related, but it also indirectly affects the depth of field and the clarity and blur of moving objects.

* * two. Light quality * *

Light quality refers to the soft and hard properties of light. It simply means that the shadows produced by light are clear and thick, with sharp outline and strong contrast; The so-called softness,

It means that the shadow produced by light is soft and inconspicuous, with gradual outline and weak contrast. Strong light has obvious directivity, which can make the main body

Produce a sharp contrast between light and dark, which is helpful to the expression of texture. Strong light often gives people a sense of fortitude and vitality; Soft light won't.

It has obvious directionality and is suitable for reflecting the shape and color of objects, but it is not good at expressing the texture details of objects, and soft light is common.

Give people a soft and delicate feeling.

The hardness of light quality is related to the size of the light source and the distance from the subject. Small and far point light source will produce obvious hard light effect.

, such as spotlights, small flashlights, direct sunlight; Large and close surface light sources are easy to produce soft light effects, such as large.

A-type masked light source, thin clouds cover the sky, etc.

Sometimes, the softness and hardness of light can be changed. Put a piece of diffusing material, such as sulfuric acid paper, between the hard light source and the object.

Soft light can be given. The bigger the diffuse object, the closer it is to the subject, and the softer the light effect.

* * Three. Brightness * *

Brightness refers to the position of the light source relative to the object. The light level in photography determines the bright and dark position of the subject and also affects it.

Texture and shape of the subject. The level of light can be ever-changing, but when the subject and the plane are relatively fixed, the level of light can be divided into smoothness.

Light, side light, backlight, top light, bottom light, scattered light.

1. Guang Shun

Directional light, also called frontal light, illuminates an object from the front. The biggest feature of daylight lighting is that the main body receives light evenly and the color is restored.

It is true and saturated, but it lacks a sense of space and three-dimensionality, which is not conducive to expressing the subject's sense of body and making the subject bright.

The dark part does not change much, and it is easy to produce gray tones.

2. Indirect explanation

Side light refers to the light irradiated from the oblique side of the subject, which is usually oriented as front light, front light and backlight.

A. Front side light refers to the front side light of 45 degrees. Is a very common light level, which will produce a convex part of the subject.

Shadow, with the contrast between light and shade, has a strong three-dimensional sense.

B. Positive light is a light level of 90 degrees. The light on the front side produces a stronger contrast between light and shade than the light on the front side, which shows the object well.

Surface texture and three-dimensional sense.

C. Backlight, also known as side backlight, comes from the back of the subject, and its biggest feature is to make the subject in a dark background.

A bright contour line is generated in front, which separates the subject from the background and has a good three-dimensional sense and a sense of space.

in a bad/poor light

Backlight refers to the light irradiated from the back of the subject. First of all, it makes the subject produce a bright outline and has a good performance.

Secondly, the backlight will give the subject and its environment a good sense of space. Third, the backlight will make it translucent.

Bodies, such as petals, have good textures, but these objects look inconspicuous in the light. It also has some shortcomings, Lord.

It is difficult to show the front details of the subject, and it is generally improved by supplementing the front light.

Step 4: dome light

The top light is the light from directly above the main body, such as the noon sun. It is rarely used in normal photography, except in special circumstances.

Special effects or alternative photography.

5. Bottom light

The bottom light comes from below the subject and is rarely used in photography. It is generally used in commodity photography and portrait photography. goods

In photography, weak light is usually used in the translucent background of small commodities to render a certain atmosphere or artistic conception. And use the bottom more in portraits.

The horror and weird effects of light are used to vilify characters.

6. Scattered light

Scattered light has no certain directionality, for example, light on cloudy days is scattered light. In terms of light quality, it is soft light, which is softer.

It is difficult for the subject to produce sharp contrast. You can take some high-value photos with scattered light, but if it is not well controlled, it is easy to make the picture appear shadows.

Adjust the gray level.
