What does clarity have to do with it? What is the relationship between pixels and low resolution? Does the clarity of rights matter? Why?

The clarity of a photo is related to many factors, including pixels, lens resolution, shooting environment and so on.

There is no direct relationship between pixels and resolution; Pixels are a factor in sharpness. Because pixels are only related to the output size of the picture. In this size range, the pixel has little influence, but once it exceeds its actual pixel, the definition will plummet. For example, if a picture with 300W pixels is enlarged to a picture with 500W pixels and compared with a picture with 500W pixels, it can be intuitively found that a picture with low pixels is not as good as a picture with high pixels, so pixels are only a factor of clarity, and only under certain conditions.
