The elements that constitute the picture of a commercial photography can be divided into main body, companion body, front, middle and back scene, and environment. Each picture element in the work needs to be represented from four aspects: shape, quality, light and color. The commercial photography later period revises the picture is USES the graph image software technical method to carry on the adjustment to the shape, the quality, the light, the color four aspects, thus produces the visual change, presents tends the true and the perfect work.

In the later retaking of commercial portrait photography, party a often requires "thin" as the ultimate goal, but the body proportion of human body and the relationship between local human body structure should always run through the process of retaking. In character as the main subjects of creation and teaching activities, has always been to "human anatomy" art as one of the main technique theory subjects, like painting, sculpture art, portrait photography late chart is to show the characters' image, face, dynamic, character, etc., so "art in human anatomy" is a must

Grasp the basics. Among them, berryman human body structure teaching book is a must. In "berryman human body structure", all the skeletal and muscular systems of the human body are comprehensively discussed and presented in the form of front view, rear view and side view. Master the knowledge of the internal structure of the human body to follow the scientific basis to complete the revision.

Goods still life photography later tend to take the picture according to party a's product positioning for the corresponding visual perception, then fix the figure architect can find inspiration in the same commodity website, and then summarized, such as "but steady changes in composition, colour and lustre is bright, the surface level off is smooth, the light is soft delicate" such as described with reference images can be provided to the direction of the repair plan division processing, and then put these visual features implemented by software.

Photography is the art of light, photography light has two basic purposes, one is to meet the needs of exposure and provide adequate lighting; The second is to control the reproduction effect of the subject. In the later retouching, light can affect the shape, tone, color, spatial feeling, aesthetic feeling and sense of reality of the subject. Light can also enhance or weaken or even eliminate some aspects of the subject's performance. Therefore, the correction and creation of light in the later revision of commercial photography is particularly important.

Light and shadow problem is a sketch relationship, a sketch relationship is the perfect picture is the premise of color perfect. The operation of changing light and shadow in the later stage is to compensate and assist the operation in the earlier stage. It is the brightness that USES curve large area to adjust integral and contrast normally, receive light according to different area again different circumstance makes local adjustment. For the adjustment of light brightness and color, the pursuit of feeling while referring to a certain natural law and logical relationship.

Photographic lighting emphasizes hard and soft, soft and hard. For example, if the overall lighting is dominated by hard light, a relatively soft light is needed to control the light ratio and tone level. On the contrary, if the light is mainly soft diffuse reflection, you need a hard light to emphasize the main body, otherwise the whole picture will be dull. Later revision of the picture should also pay attention to the hard with soft, soft with hard, soft light film to properly strengthen the main texture, need to pay special attention to the texture here is not simply sharpening. Hard light film texture is very strong but the level is not good, so late to try to put forward more dark levels.

The improvement of light sense is also obvious to the improvement of picture sense. Light is an important factor in the performance of texture. By adjusting the contrast of light and other operations, the texture will naturally become exquisite. In addition to light contrast, it is also important to change the shape of the light when adjusting the light. The combination of light and shadow can create a rich variety of visual effects. Due to the limited conditions, the early shooting can only draw some light in the later stage, so as to better achieve the expected feeling. In addition to drawing light by hand, you can also touch a variety of brushes.

Texture refers to the aesthetic feeling caused by the real expression texture of plastic art images. Stone, bark, metal has very strong simple sense, and soft cotton, pure river water, thin gauze also has their respective simple sense, because this simple sense is stronger, better not.

Texture is often simply believed to be obtained by sharpening or contrast. It has been proved that the texture produced by high-end medium frame cameras such as hasu and firth, as well as high-end flash cameras such as boffin and brown, cannot be replaced by any later sharpening and contrast. The key to the texture is to see the details, levels and tolerances of the picture acquired by the camera. On the other hand, it is to see the use of light. The equipment is good, but the intensity of light is not enough, and the intensity is not enough, and the stability is not enough. In the later stage of image editing, the most important thing is to adjust the subtle levels and local light and shadow to make the photo more detailed. Rich details are the key to the clarity and texture of the photo.

Color correction is usually enough in commercial post-production color mixing, but some styles need to depict more ambient and light source colors. We learn from the oil paintings of Raphael, van gogh and other masters to experience the treatment of color emotion. Classical oil paintings pursue realism and color, which can be understood as static expression. Van gogh's works are dynamic color expression, and every part of the picture reflects the color change of the environment. For example: see snowflake inevitable meeting thinks of cold, in hue annulus cyan and blue can behave cold, in order to the advanced feeling of color avoids pure color as far as possible so the cool gray that can choose cyan blue. Red blocks can be more magenta, because red plus blue will be magenta. If again the feeling of classic oil painting, the train of thought that mix color is about to slant a bit warmer as far as possible, considering the same kind of the principle that seeks different, want to be opposite proper color is not yellow local and appropriate retain primitive proper color.

General studio shot monochromatic background in the later revision does not need the adjustment of color feeling, adjust shape, light, quality is almost the same, the environment portrait need to adjust more color feeling. The first step is to determine the style and feel of the photo, and then find the right tone by analyzing the purpose of the photo and the characteristics of the elements in the photo.

Commercial photography late repairing figure depends on four elements form, texture, light and color, using graphics software technology, through the shape, texture, light, color the four elements of the visual change, more perfect present a photographer concept, understanding of the form, the control of light and shadow, the color performance, finally presents tend to be more real and perfect works.
