Beginners must learn photography and photometry in detail

Beginners must learn, photography and photometry are explained in detail.

First, learn to measure light.

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.

Second, 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. Zone metering can help you ensure that the subject is properly exposed while avoiding other areas from being too bright or too dark.

Third, the central 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 situation that the main body in the center of the picture is more important and the surrounding environment is relatively balanced. For example, when shooting portraits or still life, focus average photometry can be used to ensure the proper exposure of the subject.

Fourth, evaluate 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.

Verb (abbreviation of verb) counts light.

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 silhouette and 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.

Overview of photometry of intransitive verbs

1. Evaluation metering: It is the default metering mode of most cameras, and measures the whole picture. Often used in scenes with uniform light.

2. Partial metering: The metering area will be larger than spot metering, and only about 9% of the central area will be metered. Can be used to take close-ups of portraits.

3. Center key average metering, focusing on the central area, and then averaging to the whole. Often used in portraits, documentaries, etc.

4. Spot metering, that is, taking a spot in the picture for metering, only about 3.8% of the central area is metered. Can be used in strong backlight and other scenes. In this case, only the height of the person's face needs to be measured.
