1, aperture: the function is to control the amount of light entering the lens, and the value of the aperture follows the letter F. The larger the aperture, the more light entering, the brighter the picture, the shallower the depth of field and the more blurred the background!

2. Shutter speed: Generally speaking, it is actually the time required for the shutter to open and close. The higher the shutter speed, the shorter the exposure time, the less light entering and the darker the picture. For example, when using a focal length of 70 mm, using a shutter speed higher than 1/70 seconds can prevent jitter and cause image blur! In addition, we must remember that the shutter speed is contrary to our normal value. For example, the shutter speed of 1150 seconds is much faster than that of1second.

3. Sensitivity: The sensitivity of ISO digital camera is an index similar to film. In fact, ISO of digital camera is realized by adjusting the sensitivity of high-sensitivity photos of photosensitive devices or merging photosensitive points, that is, by improving the sensitivity of photosensitive devices or merging several adjacent photosensitive points. The higher the ISO, the more light can be captured. Increasing ISO under the same shutter can increase the aperture accordingly. However, the higher the ISO, the more noise there is in the photos taken. It is good to control the ISO of daytime scenery shooting at 100-200.

4. What is the biggest disadvantage of the reverse camera compared with the micro-single? That's really heavy! More photosensitive elements and metals and various long lenses make SLR cameras very bulky. In order to prevent camera shake, the correct way to end the camera is very important! The correct way is to hold the camera in your right hand, the lens in your left hand and the index finger of your right hand on the shutter. Remember to take pictures with your left eye and your right eye. Hold your arms by your sides, keep breathing evenly, and gently press the shutter.

5, camera mode: P file, program automatic exposure, all fool mode, don't know how to adjust the camera parameters, just try this! Television, shutter priority, program automatic exposure. In this mode, you can set the shutter speed and iso yourself. Because the program will automatically detect the aperture value, it is generally used for long exposure, such as night scene shooting and starry sky shooting. AV, aperture priority automatic exposure, you can set the aperture size yourself, and the camera automatically sets the shutter speed. M file, completely set the parameters yourself, novices can do exercises, but it is not easy to make a good film in this mode!
