1. When selecting exposure reference value, don't always use the same exposure reference value. The specific choice needs to be judged according to the current scene, and the appropriate numerical effect is good.

2. If you want to lock the metering, you need to press and hold the AE-L or AF-L button on the camera. Of course, it is a light press, not a direct press, so that the metering can be locked.

3. If you need to transfer the shooting operation, you need to follow the steps of focusing, composition and shooting. Press the lock light during the process and adjust the position before releasing.

4. When using a SLR camera, depth of field and exposure are technical terms. If you want to strengthen your personal skills, you'd better improve them through theoretical study and practical methods.

Digital camera consists of lens, viewfinder, CCD, LCD shutter and so on. The zoom lens changes the focal length, that is, the size of the image. The viewfinder is used for framing. CCD is an electronic imaging element. The area of CCD determines the size of pixels, which is what we usually call pixels. The LCD screen is used to display images or composition, the shutter is used to take pictures, and the memory card is used to store images. The larger the memory card, the more images are stored.

1. Zooming and focusing: Zooming refers to changing the imaging size. Zoom can be divided into automatic and manual, push-pull and rotation. Generally, it is manual zoom. By changing the zoom, the required imaging size can be obtained, and the focal length is the distance of the focal point. Usually, what we are talking about is clear. Nowadays, digital cameras are all autofocus. Press the shutter button to start autofocus, and then press the shutter to take pictures.

2. Aperture and shutter: Aperture is used to adjust luminous flux. The smaller the aperture value, the more luminous flux. Conversely, the larger the aperture value, the smaller the luminous flux. The main function of the aperture is to adjust the exposure, and the adjusted luminous flux reaches the standard. If the image is dark under the condition of equal light, the aperture luminous flux is small. At this time, turn up the aperture and increase the luminous flux. If the image is too bright, it means that it is overexposed and needs to be reduced to meet the exposure standard. Only images with standard exposure can take the best photos. Be sure to master the exposure.

3. White balance setting. White balance refers to the color setting of photos. If the white balance settings do not match, the captured image will appear color cast, which is usually called incorrect color. Color temperature is divided into sunlight, incandescent lamp, fluorescent lamp and flash lamp, which are generally used indoors. White Balance Automatic white balance is set in user-defined settings. When shooting large scenes with more colors, automatic white balance is more accurate, and user-defined white balance is generally used.

4. Flash synchronization setting: professional digital cameras have flash synchronization function. When taking pictures under movie and television lights, you must choose the flash synchronization block, otherwise you will not get satisfactory exposure. The synchronization setting should be set according to the camera's instructions.

5. Memory card settings: The imaging size of digital cameras is determined by pixel settings, and digital cameras are generally represented by large, medium, small or high, medium and low. The larger the pixels of the same memory card, the less the number of photos, the more the number of photos, and the fewer the pixels. Accordingly, the larger the magnification of a photo with large pixels, the smaller it is.
