How to adjust the aperture size of mobile phone

Question 1: Can the aperture of the mobile phone camera be adjusted? The aperture of the mobile phone camera cannot be adjusted.

Today's smartphone cameras all use fixed apertures. No matter what scene you shoot, this aperture is fixed and cannot be adjusted manually or automatically.

Aperture is a device used to control the amount of light entering the photosensitive surface of the fuselage through the lens, usually in the lens. We use the f value to represent the aperture size. For the manufactured lens, the diameter of the lens cannot be changed at will, but the luminous flux of the lens can be controlled by adding a polygon or circular aperture grating with variable area inside the lens. This device is called an aperture.

Question 2: How to adjust the aperture of the mobile phone camera? Aperture is an approximately circular thing composed of a group of blades, which has the following functions:

1. control luminous flux: large aperture (F 1.4) and more light, which can ensure higher shutter speed in low light environment; Conversely, the smaller the aperture (F22), the smaller it is.

2. Control the depth of field: the larger the aperture, the shallower the depth of field (that is, the better the background blur); The smaller the aperture, the clearer the foreground and background (the scene usually uses a small aperture, such as F 1 1~F 16).

3. In flash photography, the aperture can also control the light ratio between flash and ambient light. The ambient light is controlled by the shutter and the amount of flash is controlled by the aperture.

Depth of field: the clear range before and after the focal plane.

Adjustment method:

1, SLR and DC with manual function: Turn to aperture priority mode (A or AV), and then turn the thumbwheel on the fuselage;

2. Manual lens: directly rotate the aperture ring on the nose;

3. Some fully automatic DC can't adjust the aperture, but the camera can decide automatically according to the scene at that time.

Question 9: How does Xiaomi mobile phone 3 adjust the aperture function? The aperture of the mobile phone is constant.

The phone itself should be thin. Regardless of the small camera, if the aperture is variable, it takes up a lot of space.

The large aperture of F2.0, if variable, is at most F7. 1 and F8.

The amount of light entering is reduced, but the shutter of the mobile phone is insufficient. Easy to shake

Question 10: The aperture size of a mobile phone camera depends on what you shoot with your mobile phone and what the shooting distance is. Do you want the depth of field to cover everything you want to shoot? For example, if you shoot a portrait with a large aperture (f2.0), your nose may be clear and your ears may be blurred (scene depth), but if you shoot a portrait with a small aperture (f2.4) at the same shooting distance, your nose and ears may be clear. Everyone likes different things, some like clear portraits and fuzzy background buildings. Some people like people and clear background buildings. Why can most SLR lenses adjust the aperture? Because the photographer should choose the aperture value according to the distance, focal length, longitudinal depth, brightness, shutter, sensitivity and so on. But the aperture of the mobile phone is unchanged and cannot be adjusted, so there is nothing good or bad. Every aperture can make excellent films!
