What is contrast in photography? Are there many kinds of comparisons?

Although contrast does not represent resolution, it is not irrelevant, but it cannot be said that high contrast leads to high resolution. Contrast actually refers to the ability of the lens to express darkness. An image must have two contrasts, bright and dark. High contrast means that the separation of light and shade is obvious, and there may not be too many layers in the middle. Low contrast means that the light and shade are not obvious enough or bright enough, but there are many layers, which may make people feel dull. For color or black and white images, the definition of contrast is the same.

Most people misunderstand that high contrast is good, yes, high contrast is indeed more vivid and brisk, but without rich layers, the high resolution just now loses its meaning and will hinder the overall detailed performance. But contrast is a very subjective thing, there may not be a standard, but a more comprehensive lens will be more popular. Moreover, the current films also have good contrast and layers, and there are different choices, such as films specially designed for portraits and films specially designed to restore accurate colors. Photographers don't need to pursue them blindly.

The difference between light and darkness is called contrast. The difference between light and darkness is called Gao Fancha, and vice versa.
