What is the sketch texture?

Sketch texture is the inherent physical characteristics of various objects, such as hardness, weight, thickness, roughness, etc., which are expressed by certain means of expression. Texture refers to the material properties of an object. Different substances give people different visual feelings, which is texture. Such as the roughness of pottery pots, the smoothness of glass, the softness of silk and the hardness of metal.

Taking the photographer as an example, he uses modeling methods such as light, color, line, light and shade to make the photographed image not only resemble or approach the characters or scenery in the original work, but also convey the different characteristics of skin, clothing, furniture and utensils as material attributes in detail. For example, skin texture can show people's age, occupation, experience, especially their temperament. Photosensitive characteristics of film (especially tolerance, granularity and color sensitivity, etc. ), the change of color temperature and brightness of lighting source, the accuracy of photographic exposure and the color tone restoration during development and printing are all factors that affect the accurate expression of texture. In color photography, the errors of light distribution and color correction often affect the performance of people, scenery and objects.

Visual or tactile sense of the characteristics of different states of matter (such as solid, liquid and gas). In plastic arts, grasping the realism of different objects with different skills is called texture. The natural characteristics of different substances are called natural textures, such as air, water, rocks, bamboo, etc. The expression after artificial treatment is called artificial texture, such as brick, ceramic, glass, cloth, plastic and so on. Different textures give people a variety of feelings such as softness, truthfulness, smoothness, tenacity, transparency and turbidity.
