Light is the effect of light. You should know the application and understanding of light, have a basic understanding of the performance of light, and use all kinds of light flexibly to draw more vividly. The use of color is also very important. Without color and proper tone, you can't draw a good picture, which is the basic knowledge you must have to appreciate a painting.
Modern oil painting schools can be divided into two categories, abstraction and impressionism, and of course, impressionism, fauvism, futurism and so on. Abstract school is an imaginary concept. In nature, there are no such images, only some color blocks, lines and so on. Because of the combination of these color blocks, people call it abstraction.
Impressionism, also known as realism, has this image in nature, but it needs to be expressed in the form of painting. The characters and objects in Impressionism are all real, and painters show them in various colors and strokes, which makes people realize its wonders.
When appreciating an oil painting, we should also understand the background of the times in which the author lives and create the ideological content of this painting. When a painter creates a painting, he takes his own thoughts and embodies the artist's artistic realm. We appreciate it and have a perceptual voice. When the painter created this painting, he also shaped different characters according to his own life experience, different understanding of the characters and different depths. A good work can cultivate people's feelings, improve people's spiritual realm, discover the beauty of the world, and let us have a deeper understanding of the world, the specific characters and the scenery.
