Why does the mobile phone always shake when taking pictures?

Let's talk about horizontal screen first. I use Huawei mobile phones, and all brands of mobile phones have gyroscopes, so in theory, mobile phones can sense their own state, which should be vertical, but only for standing objects. But when the object suddenly lies flat and the camera shoots from top to bottom, it is impossible to judge whether it is horizontal or vertical. It is suggested to put the mobile phone vertically or horizontally in the direction perpendicular to the ground first, and then put the mobile phone horizontally, so that the horizontal screen and vertical screen can not be wrong.

Photography and shooting are the same thing. If you miss after aiming, you may be affected by pulling the trigger with your fingers, shaking your hands, heartbeat and breathing. Therefore, shooters have to undergo long-term training to overcome difficulties. When shooting, the hand will shake when pressing the shutter, and the hand itself will shake, and breathing will make the lens unstable. There is also the influence of exposure time. The more light, the shorter the exposure time, the less the photo is affected by jitter, the weaker the light, the longer the exposure time, and the greater the photo is affected by jitter.

The force of finger pressing the shutter makes the camera shake, which can be solved by fixing the shooting time for 3 seconds. Hand tremor can be solved by clamping the arm between the ribs. Respiratory effects can solve it by holding his breath.
