What are the main points of photography?

Three elements that should be paid attention to in photography:

The three elements of photography: "focus, exposure and composition" are the basis of photography. The so-called exposure refers to the photosensitive intensity of negative film or CCD photosensitive element; If the light can't be adjusted to the most appropriate intensity, the negative and CCD can't record and confirm the image correctly. The intensity of light can be controlled by adjusting the "aperture" and "shutter speed".

1. Clear focus.

"The people in the photo look foggy! ! "Generally speaking, this kind of problem is the problem of focusing. There are several skills to focus well:

● Recognize the key points:

Generally speaking, the focus of a digital camera is in the center of the camera. You can see a small frame on the LCD of the camera. When taking a photo, please aim at the person in the small box first, press the shutter half and hear the beep. At the same time, a small green light will light up (depending on the camera type), indicating that the camera is in focus.

● Whether the subject is in focus:

1. People-oriented.

2. Press the shutter half way to finish focusing first. At this time, don't let go of the hand that presses the shutter, or the focus will deviate.

3. Move the person to one side. After the composition is completed, press the shutter completely to complete the photo. Because it has been focused before, the focus will not deviate.

Pay attention to hand shaking:

Stable camera shooting is the only way, so always pay attention to the shutter speed. Digital cameras now display shutter and aperture data. Generally speaking, the so-called safety shutter is not less than 1/30 seconds. If the shutter value is lower than 1/30, use a tripod to increase stability.

2. The exposure should be correct

● What is exposure (exposure compensation)?

Exposure value mentioned in traditional photography is the so-called EV value. You can make the adjustment of+/-,that is, the adjustment of exposing one frame more (brightening) or one frame less (darkening) to make the image more correct when exposed, so that the photo will not be too dark or too bright. (Now all digital cameras have EV keys. )

Formula: black is black, and bright is bright.

If the subject is dark, the EV value should be reduced (changed to dark).

If the subject is bright, increase the EV value (become bright).

At present, digital cameras automatically calculate the best exposure value. But in some cases, the camera will be deceived by the shooting environment, leading to misjudgment.

Pay attention to the environment:

Usually, if the background is too bright, it may be that the protagonist is standing in front of a white wall, or wearing white clothes, or on a white beach, or in the snow, which will cause the background brightness to be greater than the main body. This is when the formula comes in handy. On the contrary, if you wear dark clothes or the background is too dark, you should lower the EV value.

● Flash:

Flash can be used not only at night, but also at the right time during the day, which can increase the correct exposure.

3. The composition should be special

After getting familiar with the first two techniques, let's look at the last and most important technique: composition.

General composition has the following steps:

● Gold composition:

The composition of gold is divided in equal proportion, and the division ratio is 2: 3, 3: 5, 5: 8, etc. , that is, cut out lines with equal proportions in the photo, and then arrange the scenes in the photo to present a ratio of 2: 3.

● Jiugongge composition:

The intersection of the four lines of the nine squares is the most sensitive place for the human eye. These four points are also called "interesting central points" in foreign theories. As long as you master these four points to compose a composition, you can ensure that the photos you take are no longer photos of life.

The composition of Jiugongge can be used in many places, such as photographing the coastline. You can put the coast above 1/3 or below 1/3, which can create different feelings. Don't put the coastline in the middle of the picture.
