The retouching refers to the retouching of people, still life and scenery pictures. It is widely used in photography, design, publishing, e-commerce and other fields. Retouching can usually be divided into the following categories. Character body retouching through the character body retouching, you can better show the effect of clothing on the character wearing, highlighting the beauty of the clothing. Skin retouching With the development of technology, the pixels of cameras are getting higher and higher. When taking pictures of people, if the pictures are used to show close-ups, the flaws on the skin of the people will be enlarged. The texture of the skin can be enhanced through post retouching process.

Landscape retouching retouching also includes retouching of landscapes. Retouching allows some aesthetic scenes or gorgeous colors to be re-presented in the picture. Theoretical knowledge of retouching only understand the operation of the software is not competent retouching work, retouching must have a basic theoretical knowledge as the basis and guidance. Here will explain the basics of retouching - the relationship between light and shadow and physical aesthetics. The relationship between light and shadow refers to the relationship between light and darkness after the light hits the object. An object can only be three-dimensional in a flat surface if there is a change in light and darkness. The relationship between light and shadow is the most basic element of a picture. It includes three major surfaces and five major tones. When an object is exposed to light, it will show different light and dark changes. The area that is exposed to light is brighter and is called the bright side; the area on the side is called the gray side; and the area that is backlit is called the dark side. These are the three major surfaces. The five major tones is a subdivision of the three major surfaces, the following detailed explanation of the specific meaning of the five major tones. The first is the bright side, that is, the lighted side, the lighted side of the focus of light called "highlights". In retouching usually use highlights to reflect the texture of the object. The second is the gray side, refers to the side of the object by the light irradiation area and the transition zone of the light and dark lines. This area is rich in light and darkness, and has more layers. The third is the light-dark boundary, because it is affected by the ambient light, but not by the main light source, so the contrast is strong, here is usually the warmest area on an object. The 4th is the reflection, which refers to the reflection of dark areas as they are illuminated by reflected light from the environment or object. It is not the darkest area on the entire object, and it is brighter relative to the light/dark border. The fifth is projection. A shadow is created when an object is exposed to light. Typically the edges of the projection are sharper the closer they are to the object and blurrier the farther they are from the object. Physical aesthetics is necessary to understand what "beauty" is when you are working on a figure, so you need to learn about physical aesthetics. The standard human body proportion is 7~7.5 times the height of the head, and the width of a person's arms is equal to the height. Measure the proportion of the human body is generally the length of the head as a unit, such as the length of the neck is 1/3 of the head length, the upper limbs for the 3 head length, the lower limbs for the 4 head length. When drawing or retouching, the head-to-body ratio of a person is usually slightly exaggerated, which can make the person look more slender and beautiful. The proportions of a figure are different in different poses. There is a mnemonic in painting - "standing seven sitting five disk three and a half", which refers to the proportional relationship between the head and body when a person is in different poses. All these ratios can be used as references for actual retouching work. In addition to the proportion of the human body, the human face is also very important in the retouching of characters, one of the key points of facial adjustment is the face shape. The face shape is mainly determined by the bones of the face and skull, and common face shapes are categorized as follows. Generally, a melon face or goose egg face with an oval head and a pointed chin is beautiful. For men, in addition to melon face and goose egg face, national face is also a good-looking face shape, which will make men look tougher and more masculine. In addition to the outer contour of the face, there is another very important standard of the five senses to measure the beauty of the face - three courts and five eyes. Three court refers to the length of the face, that is, the distance from the hairline of the head to the jaw, is divided into three parts, from the hairline to the eyebrow, the eyebrow to the tip of the nose, the tip of the nose to the jaw is divided into one part, each part is called a court, a **** three court. Five eyes is the width of the face is divided into five eye length, the distance between the two eyes for the length of one eye, the two sides of the outer corner of the eye to the ear each has a length of one eye. There are also standards for the aesthetics of the five eyes, such as standard eyes with the outer corners of the eyes slightly higher than the inner corners of the eyes, and the inner corners of the eyes should be open; when the eyes are looking at a flat surface, the eyelids are evenly curved, and the eyelids are not pressed against the eyelashes; the upper and lower eyelids are naturally articulated with the black eyes; the upper and lower eyelashes are thick and curly, and the eyes are clear-cut in black and white. Standard eyebrow means that the eyebrow cannot be lower than the head of the eyebrow, only slightly higher or flatter than the head of the eyebrow; the head of the eyebrow, the waist of the eyebrow and the tail of the eyebrow each account for 1/3, the peak of the eyebrow accounts for 1/3 from the head of the eyebrow to the end of the eyebrow; from the head of the eyebrow to the end of the eyebrow from thick to thin, the color of the head of the eyebrow is sparse and light, the waist of the eyebrow is dense and thick, and the tail of the eyebrow is thin and light. The most important thing about the lips is the ratio relationship between the upper lip and the lower lip, usually 1:1.5. In the standard lip, the upper lip must have a more obvious lip peak and lip valley, the entire outer contour of the upper lip is an arch, and the lower lip must have a more obvious highlight lip bead, so as to better reflect the three-dimensional sense of the lips. The ends of the nose of the standard nose should not be too wide, it should be just the same as the width of the inner corner of the eye, that is, the width of an eye; the bridge of the nose should be higher and more straight, and the center of the eyebrow to the tip of the nose should be presented as an inverted triangle; the side shadow of the nose should not be too dark or it will be dark. In addition to the above knowledge, if you can understand more about the human body's bone and muscle distribution, the shape of the muscles, you can be more comfortable to modify the character.
