Is the definition of fsr as high as possible?

Actually, in the field of photography, high definition is a double-edged sword. On the one hand, it makes the visual effect of the picture clear. On the other hand, due to the improvement of contrast, some unpleasant big details are enlarged and small details are covered.

For example, in portrait photography, the excessive sharpness makes the small scars and pimples of people's skin magnified and prominent (that is, more obvious than the actual naked eye), resulting in rough and dry face. Of course, documentary portraits can be ruled out.
