In the usual appreciation process, students often confuse contrast and contrast, regard contrast as contrast, or on the contrary, some simply grab their eyebrows and beards, and when they encounter these two techniques, they are vaguely called contrast. In reality, because people often use contrast and contrast together, some people mistakenly think that contrast and contrast are the same thing. In fact, contrast and contrast are two different expressions and cannot be confused.
Contrast is a way to put contradictory things together and compare them with each other. Contrast can intercept two different things or two different aspects of the same thing. Through the comparison between the two, the beauty and ugliness of the image are more distinct, the characteristics of both sides are more obvious, the advantages and disadvantages are more profound, and the contradictions are more acute.
