You have a lot of questions, so you need to be patient and answer them slowly.

The concepts of shutter and aperture.

Why study shutter and aperture? Because they directly affect the imaging effect of photos.

Usually, normally exposed photos have a combination of shutter and aperture. For example, if you shoot a girl in the sun, the shutter 125 and the aperture are 5.6. This is the shutter and aperture of this photo. These two data are combined into a normal exposure photo. If you lower the aperture to 16, the photo is obviously underexposed. It looks gray and ugly. Generally speaking, normal exposure value, finding photos, is the best. Underexposed PP is not good-looking, and overexposed PP is not good-looking.

For example, when the aperture is 5.6, you open the shutter to 60, so that the light coming in is large and the photo will be overexposed. The loss level is not good either.

So no matter what photos you take, you should pay attention to the values of shutter and aperture. The faster the shutter, the larger the aperture. Among them, we should pay attention to the change of numbers. Usually we say shutter 125, and the shutter speed is 125 for one fifth of a second. When you say shutter 30, it is one thirtieth of a second. Much slower than 125.

Conversely, the smaller the aperture value, the larger the aperture. For example, the aperture of 2.8 is very small, but it may be the largest aperture in the camera. For example, 32 may be the smallest aperture in the whole camera.

This is more complicated. I don't know if you understand. Whether you use a SLR camera or a digital camera, I suggest you set the camera mode to A mode when shooting. I.e. aperture priority mode.

Is to fix your aperture and then the camera automatically adjusts the shutter. This will save a lot of things.

When you need the effect of large depth of field, you turn the aperture to the maximum, such as 2.8. Then the camera automatically adjusts the shutter to ensure the normal exposure of PP.

When you need a small depth of field effect, the opposite is true.

What is depth of field? What is the foreground and background?

Simply put, if you shoot a girl, the background behind the girl is very hazy, that is, the depth of field is small. The effect of small depth of field is suitable for portraits, which is very beautiful. That girl is called the front desk, and the backstage is the girl's deep backstage.

Three data that determine the depth of field: (This is very important)

The distance between the camera and the subject. The closer the distance, the smaller the depth of field. (The more blurred the background)

The size of the aperture. The larger the aperture, the smaller the depth of field. (The more blurred the background)

The distance between the subject and Beijing. The greater the distance, the smaller the depth of field. (The more blurred the background)

Generally speaking, shooting landscape PP is more suitable for using large depth of field, which means that the whole picture of foreground and background is very clear. To achieve this effect, lower the aperture and slow down the shutter. Do it. Of course, you can open the aperture to the minimum and the shutter to the slowest. However, this is usually not desirable. Because the shutter speed is too slow to hold the camera stably, the PP taken must be hazy. Unless you have a tripod to help.

For beginners, the shutter speed must reach at least 125 to hold the camera steady. A better 60 can stabilize.

Telephoto? It's just that the focal length of the lens in the camera is longer. Such as 135MM lens. 80MM, 105MM, all telephoto.

Zoom? It is the focal length of the camera lens, which can be adjusted. For example, my lens is zoom 18- 135 mm, and most camera users who want convenience will choose to equip their cameras with zoom lenses. A mirror travels all over the world. How convenient it is to go anywhere without changing the lens.

If the focal length of the lens exceeds 45MM, it belongs to telephoto. A lens shorter than 45 mm is a wide-angle lens. My lens 18- 135 mm zoom is good, including wide angle, medium focus and telephoto functions.

Focusing means that when you use the manual function, you have to rotate the thing in front of the lens yourself to focus clearly. Is to take a clear picture of the person's face, and then you can press the shutter.

Most people will use the autofocus function to focus in the form of half-pressing the shutter, and then press the shutter again.

Wide angle lens? For example, I once reduced the lens to the shortest, that is, 18 mm, to shoot a scene. The scene I see in the lens will be bigger than what I see with my eyes, because the wide angle distorts the scene in order to collect the widest range possible. Usually take a wide-angle shot of a building, and after taking PP out, you will find that the original straight line has become curved. It's deformed. The wide angle of the coastline will also change from a straight coastline to an arc coastline.

Composition? You must learn this. It is suggested to look at design and art textbooks and learn about "plane composition", which will be of great help to your photographic composition. But for a beginner, you'd better compose music according to your own wishes, don't be so anxious, and then sum up your experience after PP comes out.

Cloth light? Are you talking about the lighting in the studio? Now I suspect that you are a student of portrait photography. Apprentice. Hmm. How interesting

In portrait photography, there are generally four kinds of light, main light, auxiliary light, bottom light and background light.

Of course, the main light should be turned closer. Stay away from auxiliary lights as supplementary light sources.

The distance from the character is similar to the distance from the main light. It is used on the ground, and the light hits the chin of the character.

The background light sparkled against the background.

If you have a chance to watch photographers take pictures, you will know how to make the best use of these four lamps.

Modeling? It's the model's clothes, hairstyle and makeup. It also includes the actions and postures that the photographer involved for her. How to look good, how to put it. Generally speaking, people who have studied dance modeling training are best at posing.

Engaged in portrait photography for many years, can do but can't speak. I hope you can understand.
