Photography is necessary for beginners.

1. Learn photometry

Evaluation metering, partial metering, spot metering and central key average metering. Photometry refers to the process that the camera measures the light intensity of the object being photographed. The camera needs to adjust its exposure parameters according to the light intensity of the object to ensure the brightness and color accuracy of the photo.

Photometric mode is a setting in the camera, which determines how the camera measures the light intensity of the photographed object and how the camera will determine the exposure parameters according to these measurement results. Different metering modes are suitable for different shooting scenes and shooting purposes. When choosing the metering mode, photographers need to choose the appropriate mode according to the actual situation to ensure that the photos they take achieve the expected results.

2. Center key average photometry

Center-focused average photometry is a traditional photometry mode, which takes the center of the picture as the main reference area and considers the light changes in the surrounding areas. This mode is suitable for the subject in the center of the picture, and the surrounding environment is relatively balanced, such as shooting portraits or still life. Focus average photometry can be used to ensure the proper exposure of the subject.

3. Partial measurement

Partial metering is also called zone metering, which is similar to spot metering, but it covers a large area (about 10- 15% of the picture). This mode is suitable for shooting scenes with large differences in light brightness, but it does not need to be as accurate as spot metering. When you shoot concerts, stage performances, etc. Area metering can help you ensure that the subject is properly exposed while avoiding other areas from being too bright or too dark.

Evaluation photometry

Evaluation photometry (Canon) or multi-area photometry (Nikon) is an intelligent photometry mode. The camera will automatically analyze multiple areas in the picture and comprehensively calculate a suitable exposure value. This mode is very suitable for all kinds of shooting scenes, especially in the environment with complex and changeable light. When you are not sure which measurement mode to use, evaluation measurement/multi-zone measurement is a good choice.

5. Spot metering

Spot metering is a very accurate metering mode, which only considers a small area in the picture (usually accounting for 3-5% of the whole picture) to calculate the exposure. When shooting high contrast scenes, such as contour backlight, spot metering mode performs very well. Spot metering can make you focus on the most important part of the picture, ignoring the influence of other areas, and make your work more artistic.

6. photometric summary

Evaluation metering: It is the default metering mode of most cameras and measures the whole picture. Partial metering: often used in scenes with uniform light. Compared with spot metering, the metering area is larger, and only about 9% of the central area is metered, which can be used to shoot close-ups of portraits. Center focus average photometry: focus on the central area, and then average to the whole, often used in portraits, documentaries and so on.

Spot metering: a spot metering in the picture, only about 3.8% of the central area, can be used for strong backlight and other hopes. Scenes that only measure the height of the face.
