Professional photography questions

The professional functions of the phone camera mainly involved the following aspects: ** 1. Metering Mode ** 1. ** Matrix Metering (Evaluation Metering)** - Working principle: Metering a wide area of the screen. The camera would take into account the brightness of multiple areas in the picture and then calculate a suitable exposure value based on the overall light distribution to ensure that the brightness of the entire picture was balanced. - [Usage: It is suitable for shooting scenes with relatively uniform light, such as landscape photos. It can make the exposure of the whole picture more moderate and avoid the situation of partial brightness or darkness.] 2. ** Center Illumination ** - How it works: Metering the entire picture, but the largest proportion is allocated to the central area. In other words, when the camera calculated the exposure value, it would focus more on the light in the center of the picture, and also take into account the light in other parts of the picture, but the light in the center area had a greater impact on the final exposure value. - [Usage: It is suitable for shooting scenes where the subject is in the center of the picture and the difference between the subject and the background light is large. For example, shooting a bust of a character in the center of the picture can ensure accurate exposure of the subject.] 3. ** Spot Metering ** - How it works: Meters about 2.5% of the area around the photo. This light measurement mode only focused on a very small area of the picture, and the camera would determine the exposure value of the entire picture based on the brightness of this small area. - [Usage: When the contrast between the subject and the background light is very strong, and you want to accurately control the subject's exposure.] For example, when shooting an actor on stage, the background was very dark, but the actor had a spotlight on him. Using spot photography to measure the brightness of the actor's face could ensure that the exposure of the actor's face was correct. ** 2. Light sensitivity (USB)** 1. ** Description **: Light sensitivity represents the sensitivity of the camera to light. 2. ** Principle and Impact ** - The higher the sensitivity value, the higher the sensitivity of the camera to light. In a dimly lit environment, such as at night or in a dimly lit room, increasing the USB value would allow the camera to capture more light and take a brighter photo. - However, the higher the sensitivity, the more noise the picture would have, and the clarity and color of the photo would be affected. Therefore, in the case of sufficient light, the USB was generally set to a lower value to ensure the quality of the image. In a dim environment, the USB needed to be increased according to the actual situation, but it was also necessary to pay attention to avoid being too high to avoid damage to the image quality. ** 3. Shutter Speed (S)** 1. ** Description **: It can be simply understood as the time taken by the camera to take a picture. 2. ** Principle and Impact ** - The faster the shutter speed, for example, when shooting fast-moving objects (such as running athletes, speeding cars, etc.), the instantaneous state of the object could be clearly captured. Because the light entered the camera for a short time, the movement of the object in a short period of time would not cause the image to be blurred. - The slower the shutter speed, the more it could record the trajectory of the object. For example, when shooting traffic or running water in the night scene, using a slower shutter speed, the light could enter the camera for a longer period of time, forming a light track or flowing water effect after a long exposure. However, when the shutter speed was slow, if the camera or the subject moved, it was easy to cause the picture to be blurred. Therefore, when a long exposure was needed, a tripod might be needed to hold the phone still. ** 4. Exposure-compensation (RV)** 1. ** definition and function **: It is used to change the recommended exposure value of the camera to make the photo brighter or darker. 2. ** Principle and operation limitations **: It controls the exposure by changing the shutter speed and sensitivity. The exposure compensation function could only be used when the shutter speed and sensitivity were both automatic. Once the shutter speed or sensitivity was set to a fixed value, the exposure compensation function could not be used. ** 5. Focus Method ** 1. ** Single autofocus (AF-S)** - Working principle: The camera will automatically focus once, and after focusing, it will no longer change the focus distance. - [Usage: It is suitable for shooting still objects, such as shooting a building in the scenery or a person in a pose. After focusing, it can ensure a clear image of the subject.] 2. ** Continuous autofocus (AF-C)** - How it works: The camera will automatically focus again when there is a big change in the framing picture. This focusing method could continuously track the movement of the subject, ensuring that the subject was in clear focus in the picture. - [Usage: It is suitable for shooting moving objects, such as shooting athletes or flying birds.] 3. ** Manual Focus (MV)** - Working principle: The photographer controls the focal distance from the nearest point to infinity. The photographer could manually adjust the focusing distance to achieve special effects according to his own creative needs. - [Usage: It can be used in creative shooting situations, such as when you want to take photos with a blurred background or a clear background and a blurred background, and the subject is not in an area that is easy to identify with autofocus.] ** 6. White Balance (DB)** 1. Principle: Light has colors, and different light sources will make objects appear different colors. The role of white balance was to adjust the color difference to ensure that under different colored light sources, white objects were still white. 2. ** Operation method and influence ** - White Balance provided many modes that corresponded to the colors of common lights. It also provided a manual mode. In the manual mode, the color would be blue when the white balance value was low, and red when the value was high. Under normal circumstances, selecting AWB would allow the camera to automatically adjust the color according to the light source to ensure that the image color was not affected by the light source color. However, in some special creative scenes, such as when you want to create a warm or cool atmosphere, you can manually adjust the white balance value. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
