How do photographers avoid hand shock and machine shock when shooting?

Therefore, how to avoid it when shooting has always been a major problem in the photography industry. In order to solve the influence of hand shake on imaging, in addition to improving the photographer's own technology, major manufacturers are also constantly developing and innovating in technology, and strive to solve the influence of hand shake on imaging. So far, the anti-shake technology of digital cameras has evolved into three categories, namely optical anti-shake, electronic anti-shake technology and photoreceptor CCD technology. Optical anti-shake: When the gyroscope built in the lens detects a slight movement, it will transmit the signal to the microprocessor for calculation. After calculating the displacement to be compensated, the compensation lens group will compensate according to the shaking direction and displacement of the lens, thus overcoming the fuzzy influence caused by camera vibration. Canon IS system can generally complete the movement of the IS lens group in a very short time, which can usually effectively prevent the jitter when the shutter time is shorter than 1/60s. Electronic anti-shake is to analyze the image of about 2/3 area on CCD, and then compensate with edge image. At present, cameras in most photo studios in Nantong adopt this method. However, this method will inevitably reduce the utilization rate of CCD, and it is not very helpful for still images. CCD anti-shake is usually called "electronic anti-shake of fuselage". In fact, its effect is different from the real electronic image stabilization. Its representative manufacturer is Konica Minolta. The principle of CCD anti-shake is to put the CCD on a bracket that can move up, down, left and right, and then when the gyro sensor detects the jitter, it will process the parameters such as the direction and speed of the jitter and the movement amount of some columns, and then calculate the CCD movement amount that is enough to offset the jitter. Compared with optical anti-shake technology, CCD anti-shake technology can effectively avoid the spherical aberration caused by compensation method. At the same time, it can also solve the volume limitation that plagues the lens change of SLR. But its disadvantage is that the cost of the fuselage is too high, and the actual imaging area will increase after CCD offset.
