The following is a detailed explanation of the photography parameters: ** 1. Basic parameters ** 1. ** Aperture * - ** Method and principle **: Expressed by F value, such as F2.8, F4, F8, etc. It controlled the amount of light that entered and affected the depth of field at the same time. The lower the F value, the larger the aperture, the more light entering, and the lighter the depth of field (the background is easy to blur); the higher the F value, the smaller the aperture, the less light entering, and the greater the depth of field (the front and back scenes are clear). - ** Usage scenario **: - Small aperture (such as F16): suitable for scenery, buildings, and other scenes that require a large depth of field. It can make most of the elements in the picture clear and focused. - Large aperture (such as F2.8): suitable for portraits, flowers, and other scenes that need a blurry background. It can highlight the main body. 2. ** Shutter Speed ** - ** Method and principle **: In seconds, such as 1/1000s, 1/250s, 1/30s, etc. It controls the exposure time, which is the length of time the light shines on the image sensor. - ** Usage scenario **: - High-speed shutter (such as 1/500s or faster): used to shoot sports scenes, to ensure clear images of moving objects, such as sports events, fast-moving animals, etc. - Slow shutter speed (such as 1/15s to 1 second): suitable for shooting scenery, running water and other scenes that require a long exposure time. It can shoot special effects such as the fog effect of running water or star track. 3. ** Iso-sensitivity ** - ** Value range and principle **: The values are such as 100, 400, and 1600. It controls the camera's sensitivity to light. - ** Usage scenario **: - Low Isos (such as Iso100): It is suitable for environments with sufficient light to obtain high-quality, low-noise images. - High Isos (such as 800 and above): suitable for environments with insufficient light, but noise may occur and affect image quality. 4. ** Focal Length ** - ** Value range and principle **: For example, 35mm (wide-angle), 200mm (telephoto), etc. It determined the perspective and the x-ray effect. - ** Usage scenario **: - Wide-angle focal length (such as 35mm): suitable for shooting scenery, buildings, etc., able to show a wider scene. - Telephoto focal length (e.g. 200mm): suitable for shooting long-distance objects, portraits, etc. It can zoom in and compress the background. ** 2. Advanced parameters ** 1. White Balance - ** Scene Selection and Principle **: There are automatic, daylight, cloudy, fluorescent lights, and other modes. Its function was to adjust the color temperature of the photo to ensure that the white color was restored. - ** Usage **: Choose the appropriate white balance mode according to the actual light source conditions. Generally, the automatic white balance can meet most daily shooting needs. It can be manually adjusted in special scenes or when you want to create a special atmosphere. 2. ** Metering Mode ** - ** Mode selection and theory **: Including center-emphasized, spot, matrix, etc. It determines how the camera measures light to determine exposure parameters. - ** Usage scenario **: - Matrix Metering (Evaluation Metering): Metering the entire picture, which can satisfy the shooting of most scenes. - Center Focus Metering: Metering area is about 1/3 of the middle of the picture. It is suitable for situations where the subject is located in the center of the picture and requires accurate exposure. - Spot Metering: A single spot of about 3% - 5% of the image is used to accurately measure specific small areas, such as close-ups of actors on the stage. ** 3. The exposure control mode ** 1. ** Program auto exposure mode ** - ** Characteristics and application scenarios **: The camera automatically chooses the combination of aperture and shutter speed. It was suitable for beginners and scenes that did not require too much interference with the exposure settings, such as daily snapping, recording life and travel, etc. 2. ** Aperture priority mode ** - ** Characteristics and application scenarios **: The photographer sets the aperture value, and the camera automatically chooses the appropriate shutter speed. It was suitable for scenes that required control of the depth of field, such as portraits (to blur the background), flower shots, and so on. 3. ** Shutter priority mode ** - ** Characteristics and application scenarios **: The photographer sets the shutter speed, and the camera automatically chooses the appropriate aperture value. It is suitable for scenes that require control of motion blur, such as shooting moving scenes (determining whether moving objects are clear or blurred). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
