What are the different characteristics of realism and expressionist painting?

This is a different period of two different genres, the former is the French school born in the mid-nineteenth century, the representative figure is the French painter Courbet. The latter is the twentieth century painting school in Europe and the United States, which is divided into Abstract Expressionism, German Expressionism, German Neo-Expressionism, etc. Abstract table was born in the United States, the main representative of Pollock, German table was born in Germany, the representative of Lüpertz, Baselitz, and so on.

Realism and Expressionism are both art movements across the fields of literature and painting, and their paintings bear no resemblance to each other from subject matter to presentation, from technique to style.

Realist painting belongs to the field of traditional painting, with realistic shapes, and the main subjects are mostly real-life themes, mainly exposing the sufferings of the working people at the bottom of the hierarchy, with a certain color of political struggle.

Expressionist paintings mainly emphasize the expression of the artist's personal emotions, neither realistic nor concerned with real-life social subjects, without the concept of political and social criticism, they use color and brushstrokes to emphasize the artist's personal emotions, and in this way to fight against the modern city that has lost its human nature, rather than the artist's ideas to fight against it conceptually.

From the point of view of painting technique, realism painting belongs to traditional realistic oil painting, following the multi-layer indirect painting method of classical oil painting; expressionism belongs to modern oil painting, mostly using one-time direct painting method.
