Commonly used aperture parameters for cameras
The commonly used aperture parameters for cameras were F1, F1.4, F2, F2.8, F4, F5.6, F8, F11, F16, F22, and so on. When shooting portraits, close-ups, still life, and stars, you can choose a large aperture (such as F1.8) to increase the blurring effect; when shooting scenery and buildings, you can use a small aperture (such as F8 - F11 for shooting ID photos to reduce blurring and make the whole clear).

Canon Aperture precedence parameters
In Canon cameras, the aperture priority mode was labeled as Audition Mode. Aperture priority was a semi-automatic shooting mode. The user could choose the aperture (aperture value), such as f1.4, f2.8, f11, etc. The smaller the aperture value, the larger the lens opening, the more light entering the lens (brighter), and the deeper the depth of field. The larger the aperture value, the smaller the lens opening, the less light entering the lens (darker), and the deeper the depth of field. When the shutter button was pressed halfway, the camera's automatic light measurement system would calculate the exposure value based on the selected aperture value, and then the camera would automatically determine the shutter speed. At the same time, the photographer could set the value of the camera. When using the aperture priority mode, there were the following precautions: 1. Aperture adjustment should take into account the highest shutter of the camera. In a bright environment, the maximum aperture should be used with caution to prevent the theoretical shutter from exceeding the upper limit and causing overexposed. 2. Scenery shooting usually used an aperture of about F8 - F11. If it was too large, the depth of field would be insufficient, and if it was too small, the quality of the image would be reduced. This mode is generally used when you need to control the depth of field. It is suitable for shooting with a large depth of field (landscape or group photo) or a small depth of field (portrait or macro). For example, in portrait photography, a larger aperture (such as F2.8) could be used to make the background of the character out of focus to emphasize the main body of the character and blur the background. In landscape photography, when the user wanted the image quality near and far to be clear, and the shutter speed was not important, a smaller aperture could be set. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The parameters that can be achieved by the lens 'maximum aperture
The complete series of aperture numbers were as follows: F1, F1.4, F2, F2.8, F4, F5.6, F8, F11, F16, F22, F32, F44, F64. In the lens, the fixed-focus lens uses a single value to represent the maximum aperture, such as Canon EF50mmF1.0L USM; in the zoom lens, the brightness does not change with the focal length (constant aperture) is represented by the same value. The lens whose brightness changes with the focal length is represented by the maximum aperture range value at the wide-angle end and the telephoto end. The F + value in the lens name represented the maximum aperture. The smaller the value behind f in a fixed-focus lens, the larger the maximum aperture and the higher the quality of the lens. In a zoom lens, a constant aperture with a single value was preferred, and the smaller the value behind f, the larger the constant aperture. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Internal and external parameters of industrial cameras
The intrinsic parameters of the camera were parameters related to the camera's own characteristics, such as the focal length of the camera, the size of the camera, etc. The intrinsic parameters of the camera were parameters in the world coordinate system, such as the position of the camera, the direction of rotation, etc. The camera was a map between the world coordinates and the pixel-based coordinates. When the world coordinates and the pixel-based coordinates of the control points were known, the map could be calculated. After the calculation, the world coordinates of the control points could be inferred from the pixel-based coordinates, and then subsequent operations such as measurement could be carried out. This kind of calibration-based method was also known as hidden parameters calibration-based method because it did not calculate the internal parameters of the camera (such as the focal length of the camera, the distortion coefficient of the camera, etc.). In the process of image measurement and machine vision applications, in order to determine the relationship between the three-dimensional geometric position of a point on the surface of a spatial object and its corresponding point in the image, a geometric model of the camera image must be established. These geometric model parameters are the camera parameters. Under most conditions, these parameters need to be obtained through experiments and calculations. This solution process is called camera calibration1. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Which cameras can be used with music?
After shooting a video, the beauty camera could click on more music to choose the music you liked to add to the background music. Some mobile phone cameras could choose the background music when making videos. For example, when making videos by posting pictures in WeChat Moments, you could add music. Some cameras could choose the background music after blocking the original sound. You could choose the video in the gallery and choose the background music after blocking the original sound. The editing software could also be used to add music to the video taken by the camera. First, open the phone camera to record the video and save it. Then, open the editing software to import the album video for editing. Then, click on the bottom right corner to add music. In addition, the camera can be connected to a music program source (such as a CD or recorder line output) through the AC/V output cable for dubbing. Different models of cameras (such as the LV-GS3/GS5) may have different operating procedures or input source selection. For details, please refer to the machine's instructions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The parameters are generally used for DSLR shooting
The following are some common parameters when taking a picture of the parliament with a single-lens reflex camera: 1. ** Shooting mode **: Aperture priority mode (Av mode) is more suitable. This way, the camera can automatically adjust the shutter speed according to the aperture setting to ensure the correct exposure. 2. ** Iso-value **: Usually choose a lower Iso-value, such as Iso200 or Iso400, to help ensure the details and color reproduction of the photo. 3. ** Aperture **: Between 2.8 and 5.6. 4. ** Shutter: 1/125. 5. ** White Balance **: Can be set to automatic. 6. ** Flash **: Choose E/TL mode. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
