Analysis:

There are too many questions to answer twice. Answer 1-9 first.

1, direct light

The light directly emitted by the light source is not disturbed by the medium and has obvious directionality, which can produce obvious light receiving surface, backlight surface and shadow on the illuminated object.

It can well describe the three-dimensional contour shape and texture of objects. Direct light, also called hard light, is a typical direct light. Direct light has the characteristics of intensity, color temperature and direction.

2. Scattered light

The direct light of the light source is called scattered light after diffuse reflection and diffuse transmission, and the scattered light cannot produce obvious light receiving surface and shadow on the object without obvious directivity. Typical scattered light includes skylight, ground reflected light and indoor light. Scattered light is also called soft light. Do more auxiliary light and basic light. Adding translucent materials such as soft paper and nylon in front of the strong light lamp can change the strong light into soft light.

3, high color temperature lamp

Light with a color temperature of 5600K is like dysprosium lamp sunlight.

4, low color temperature lamp

Lamps with a color temperature of 3200K are low color temperature lamps, such as iodine tungsten lamp and incandescent lamps, which are mostly used in studios and studios.

5. Color temperature: a parameter indicating the spectral composition of white light source.

6. Panchromatic light: white light

7. Monochromatic light: colored light, such as red, orange, yellow and green light.

8. Mixed light: high color temperature light and low color temperature light are mixed.

9. Strong light becomes soft light: translucent material is added in front of the strong light.

13, dynamic connection: the switching method of two shots with obvious dynamics. There is a strict difference between verb combination and action combination. Action combination is the switching mode of the same subject shot, and verb combination is the switching mode of different subject shots. For example, the last shot shows an old man walking, and the next shot will follow a moving scene. Dynamic connection is a switching method, which can make the rhythm smooth and natural.

Static and static: A switching method in which there is no obvious motion between two shots. For example, the last shot is the subway train entering the station, and the next shot is the front gate stop sign. In addition to dynamic connection and static hug, there are also splicing switching modes such as dynamic connection and static connection to produce strong effects.

10, automatic aperture and manual aperture automatic aperture and manual aperture

Almost all cameras have automatic aperture and manual aperture conversion devices. In addition to automatic aperture, professional cameras also have instantaneous automatic devices, that is, in the case of manual aperture, pressing this button becomes automatic aperture. Automatic aperture device is an accurate and convenient exposure device, which brings great convenience to camera shooting. When the brightness of the subject changes little, you can get a picture with accurate exposure by shooting with automatic aperture. However, automatic aperture is not omnipotent, and many occasions are prone to shortcomings such as inaccurate exposure or flickering brightness of the picture, which is not allowed in professional photography. In order to overcome the shortcomings of automatic aperture, manual aperture must be used. For example, when shooting a panoramic lens, a person in white enters the picture from the front of the lens, the brightness of the picture changes, the aperture automatically decreases, and the picture darkens. For another example, when shooting a picture of a person with a bright background, the automatic aperture will inevitably be small, and the face will darken and become a black face. On the contrary, when the background is dark and the aperture is large, the face of the character will be brighter and lose its texture. In the process of pushing, pulling, shaking and moving, the brightness of the scene often changes, so manual aperture is also needed, and automatic aperture will also cause bad picture effect. Third, when shooting snow scenes, you should also use manual aperture. With automatic aperture, it is easy to underexpose, making the snow gray and lose its texture.

1 1. How to shoot the post-editing?

Photography is a plastic art and a time art, but it is not a running account of recording life. All kinds of scenes must be assembled to explain a meaning or a thing interestingly. This means that you can't press the shutter when you see something meaningful, but you should consider the overall structure of the film from the content, thought and meaning of the work, and the connection between shots should have a "draft" of the shots in your mind. Specifically:

1, the concept of Jingbie. Scene refers to the viewing range when shooting, and it is a concrete method to deal with the lens picture. Vision: mainly showing the environment and atmosphere; Panorama: show people's whole body movements; Mid shot: showing most of the human body; Close shot: above the character's chest; Close-up: above the shoulders of the characters. Different scenes have different performance points.

2. consider the shooting method. Refers to the working state of the camera, which can be divided into fixed or moving state. Fixed shooting is called fixed lens, and moving shooting is called moving lens. The visual effects of different shooting methods in different scenes are also different, and they are all selected and decided according to the shooting content.

3. Make clear the purpose of the video, that is, the purpose and task of shooting these shots. Only in this way can you choose what to shoot and what not to shoot, and then you can shoot with emphasis.

For example, if you shoot the award ceremony, it shows that the awarding talents are the central intention. We should shoot more. The theme is different from the theme. The award ceremony is only the theme of the report. The real purpose is to commend and introduce the winners. This is the theme. A work without a theme is not a good work.

4. The shots taken should be related and shot in groups. A photo can be an independent chapter, and a photo can show a theme and take many shots. The content between them is not related to each other, so it is difficult to edit later. If you shoot at will, you may capture some interesting shots, but on the whole, the shots can't be connected before and after the transition between paragraphs, and there are many problems such as loose structure, reversed primary and secondary, blurred theme and so on when editing is completed.
