psWhat should I do if the large image becomes blurry after being reduced?

psThe analysis of the reason why the large image is particularly blurry after being reduced is:

1. The number of pixels is too low. Even the most basic icon symbols cannot meet the definition requirements, let alone the need to insert images into it.

2. The resolution must be increased. When reducing the image, it should not be reduced to the full size at one time, but should be reduced several times.

3. After narrowing down to the required resolution, you must adjust the curve or color level to strengthen the outline and increase the contrast to achieve a visually clear effect.

After reduction, only a fixed number of pixels can be displayed per unit area, so it is not actually denser. explain. So if you shrink it by 50%, half of the pixels are actually thrown away. But the computer has no way of knowing which ones you want to throw away. This time is related to the stretching or shrinking algorithm in PS.

When shrinking, select the option "Twice the cube is sharper". This algorithm is used to shrink the image. As shown below:
