High iso noise reduction

Have an impact. Too strong noise reduction gears will lose their original edges and details, and the high image quality of RAW may become as bad as JPG and meaningless. It is also necessary to turn on noise reduction in the original fuselage, but choose a weak gear, so as to properly remove noise and noise and perfectly retain details. After that, lightroom post-processing is used to remove noise, which is larger than the noise reduction gear in the fuselage, which can preserve details and improve image quality. Generally speaking, however, ISO can also be used with low instead of high, preferably not exceeding 640. In addition, the noise reduction function of ISO will restrict the continuous shooting speed, continuous shooting persistence and storage speed, so it is better to open the file weakly or not, and then process it in the computer.
