Pick out the photos first and delete the photos with problems. If the deletion amount accounts for more than 15% of the total, it is necessary to back it up for verification and audit! 1, the photo cannot be retouched due to extensive wear; 2 weird expression; 3. Duplicate photos; 4. The overexposure of the photo leads to the fact that the main body of the photo (especially the human face) cannot restore the details of the highlight area in a large area; 5. The underexposure of the photo causes a large area of serious spots and noise in the dark part of the photo; 6, focusing does not allow PS to be restored; 7. Photos that cannot be corrected seriously; 8. Other photos that seriously affect the overall beauty of the photos but cannot be repaired. Second, color correction, lightness and color correction. What we need to do in this step is to make the white image still white, the gray image still gray and the black image still black. Therefore, the color correction step includes black, white and gray point processing, which is usually completed by color scale or curve, and the reference target is histogram. There are two steps to correct the color. First of all, we should correct the black and white field and adjust the underexposed or overexposed photos to normal. Let's first look at what the histogram of the photo standard should look like. Note: In overexposed or underexposed photos, the adjustment tolerance range of JPG file as camera shooting format is much smaller than that of RAW format. The second is to find out the gray points in the photo, restore the gray points and adjust the color to normal. When we can't find the gray spots, we use the normal skin color of the restored characters as a benchmark to correct the colors. What kind of skin is normal complexion? This is a vague concept. Of course, there are some vague definitions of vague concepts, such as CMYK and HSB color modes. CMYK defines skin color: the ratio of cyan C to magenta M and yellow Y is about 1/3- 1/5. Magenta m is the same as yellow y or yellow y is slightly higher than magenta m, and the k value is generally 0. HSB defines skin color: H (hue (reddish) 9-20 (yellowish). S (saturation) is between 15-50. B (brightness) is between 25 and 95. There is no need to change the color mode when adjusting, just set the color sampler to the required color mode, and the sampling point should be near the highlight, free from the interference of cosmetics such as blush. Color correction based on skin color should be adjusted according to environment, light and other factors. When the overall brightness and color of the photo are corrected, it lays a good foundation for the next photo processing. In this step, many people pay attention to the correction of brightness (black and white field), but when adjusting some photos with special tone effect, they ignore the step of restoring the color to normal tone, thinking that my final result is to adjust the photos to other tones anyway, and then it is unnecessary to correct the gray points and skin color. Actually this is very wrong. If we first correct the skin color of the person in the photo to be normal, and then deliberately adjust the photo to the color cast effect in the later color matching process, then the skin color of the person in the whole photo will appear very natural, and it will not make people feel uncoordinated and abrupt when looking at the photo. In this process, if two or more people appear in the photo at the same time, we should pay special attention to the adjustment of skin color. Men's skin color is slightly darker than women's, but the color difference should not be too big. Sometimes the hands, calves, feet and the lower part of the neck will have insufficient light, which will appear darker and heavier in saturation. Pay special attention to these parts when correcting colors, and choose to adjust them separately if necessary. After the color correction step, the next step should be the basic decoration. Third, rough repair, the basic modification of photo defects is also divided into two steps, one is the basic treatment of skin, and the other is to modify the obvious puncture and spots in the control film. It is necessary to put the basic steps of skin after color correction, because the process of photo studio requires both quality and speed, so many companies regard external dermabrasion filter as a necessary means to modify skin, and dermabrasion software such as Kodak, NeatImagePro and Portraiture usually intelligently recognizes skin color. In the color correction step, we adjust the skin color to be normal and distinguish it from other colors in the background, so as to maximize the effect of the dermabrasion filter. If the overall tone effect has been set and then the skin is abraded, it may be difficult for the filter to identify the skin color, or the skin color is too close to the color of the overall or large-area background, which will affect the filter effect. The main tools used in the peeling step are stamps, repair tools and peeling filters. In this process, people and backgrounds can be decorated very cleanly. Roughing steps must meet the following criteria: 1. face and skin 1. Skin: People's skin has been carefully repaired and textured (you can use a dermabrasion filter) to preserve the normal light and shadow transition in the photo. 2. Texture: handle eye bags, forehead lines, wrinkles around eyes and laugh lines, naturally without distortion, and make necessary modifications according to the age of the guests. 3. The double chin shrinks and fades. 4. Eyes: The eye bags and dark circles are lightened by modification, and the eyes are naturally consistent. 5. Hands: modify spots, wrinkles and hair. 6. Teeth: Yellow or black need to be lightened properly. 7. False eyelashes: repair or dilute the traces of shedding or tilting. 8. Hair style is messy: messy hair is trimmed. 9. Eye mask: It can modify nature and blend with skin naturally. 10. Hairpin: Be careful not to damage the texture of the hair during the modification process. Axillary: naturally, the lines should not be blunt and abrupt, but keep the lines with the human body structure. Note: facial defects should be modified, but large moles must be preserved. If there are big scars and unmanageable defects, you can ask the customer whether to modify them. 2. Clothing 1. Expose underwear 2. Unnatural wrinkles in clothes. Trim burrs and breakage. 4. Thread tip 5. Show the pin 3 of the clothes. Background 1. CCD dirty spot. 2. Folding of the background cloth 3. Damage, footprints and creases of background cloth. 4. There are many people and sundries in the picture; 5. The background affects the beautiful lines and trees that pass through the human body. 6. Scenery that is inconsistent with the theme and artistic conception of the photo. 7. Where the aesthetic feeling of the whole picture is affected in the background. 8. Other guests requested that the retouched photos be normal and tidy after color matching and rough repair, laying a good foundation for fine processing in the future. Fourth, the color matching should meet the requirements of the theme and content of the photo. The color matching of digital photos is different from other designs. What we get is a set picture, so the colorist must know which colors to use in the adjusted picture. Because the color tone of the picture will deeply affect the impression of the finished photo to the guests, whether it can attract customers at first sight depends on the color tone, so the colorist should have the necessary color understanding. First, the basic understanding of color The three primary colors of color light are the basic elements of color composition. By mixing the three primary colors in a proper proportion, you can get various colors. In the display, R, G and B are three primary colors, red (R), green (G) and blue (B) are the basis of color matching in PS, and the mixing of the three primary colors belongs to additive mixing. The characteristics of additive color mixing are: 1. Two different colors of light are mixed to generate another color, and the more times and intensity of color mixing, the brighter the color; 2. If two colors are mixed into white, it is called complementary color; 3. The three primary colors can be mixed into all colors in the color space we choose; 4. In PS, red (R), green (G) and blue (B) are equal to or not equal to 0 and 255. When the three colors of R, G and B reach the highest value of 255, the result of their addition is white, and when the three colors of R, G and B are 0, the result color is black. The hue, lightness and purity of a color are called color elements. Color element is the most basic attribute and foundation of color. Two bright color blocks together produce a strong sense of stimulation, and two soft color blocks together produce a harmonious aesthetic feeling. Different TINT brings different visual feelings to people. By understanding the concept of TINT and mastering the rules of color matching, the theme of photo effect can be expressed intuitively and effectively. Second, the basic photos with brightness adjustment often focus on the adjustment of hue in the process of color matching. After color adjustment, it is often found that the layering is still not good, the color is not true, and it seems to float on it. This happens. First, the color matching is wrong, but the reason is that the brightness contrast of the photos is not reflected. We already know that hue, lightness and purity are called the elements of color. They are the basis of color, and the process of color matching is to adjust the contrast and harmony of these three elements, and the contrast of lightness is the most profound of these three elements, just as we often say to the color matching staff, "If the color of this film is removed, what else can you use to attract people?" . Brightness change is the skeleton of a photo, while hue and saturation change is the flesh and blood of the photo. No matter how beautiful the skin is on the deformed skeleton, it will not look good. With a beautiful skeleton, even if the skin is a little different, it won't be too ugly to integrate a little makeup. Brightness contrast is the most important factor of color composition, and the relationship between color level and space mainly depends on the brightness contrast of color, which is the key to determine whether the whole photo is bright, clear, dull, soft, intense and hazy. In color contrast, there is a saying that the first-level lightness contrast is equivalent to the third-level purity contrast. Generally speaking, in lightness contrast, it is pleasant, lively, soft, weak, brilliant and light; Low-key, simple, rich, dull, heavy, melancholy, mysterious and lonely. Strong brightness contrast, strong sense of time and clear image. When the lightness pair is weak, the overall uncertainty appears soft and quiet, soft and fuzzy. We need to adjust the brightness according to what kind of final effect we need to achieve. If the brightness contrast of the photos taken is too strong, they will feel stiff, dazzling and simplistic. At this time, it is necessary to reduce the contrast and rationalize the overall contrast of the photo. If the brightness contrast is too weak, the content of the photo will be flat and fuzzy, and even if the hue is adjusted, the color will feel unstable and floating. At this time, it is necessary to increase the contrast and make the picture clear as a whole. In the early stage of color matching, we can use the color gradation curve tool to adjust the brightness of the whole or part, enhance or weaken the brightness contrast, and use the dimming deepening tool for depth processing in the whole rendering. Third, hue adjustment hue refers to the appearance name of color, which is the main basis for distinguishing colors and the main factor of color characteristics. Hue-based color matching is generally based on color phase rings, which are divided into ten color phase rings, twelve color phase rings and twenty-four color phase rings. Among them, the 12 color phase ring takes three primary colors as the basic tone; Each tone is independent in position, clearly distinguished, arranged in the same order as rainbow and spectrum, easy to master and intuitive to display. We can learn color matching from the 12 color circle. Icochromatic phase loop consists of primary color, secondary color and tertiary color. 1, the primary color is the most basic color, because the color light is red, green and blue as the primary colors, so we first draw the light of the three primary colors of red, green and blue on the equilateral triangle. 2. Secondary colors are three colors that are made by mixing any two adjacent primary colors. These colors are secondary colors: cyan, magenta and yellow. We see that the secondary color is the complementary color of the primary color. 3. Adjacent primary colors and secondary colors of the third color are mixed in pairs to obtain the third color. 4. 12 hue potential ring is defined by three primary colors, three secondary colors and six tertiary colors. The angles formed by the colors in the 12 dot color ring can be divided into monochromatic phase, adjacent color, similar color, medium difference color, contrast color and complementary color. When matching colors, 2. Adjacent colors: the hue difference is very small, the contrast is weak, and the uniformity is extremely high, but it is easy to be monotonous. It is necessary to make up for the lack of hue sense with the change of lightness and purity contrast. 3. Similar colors: the hue difference is obvious, the contrast is remarkable, the colors alternate with each other and contain the same pigment, which is vivid and energetic, unified, soft and clear, and at the same time has the advantages of implication and attraction. But if you don't pay attention to the changes of lightness and purity, it will easily become monotonous. In order to change the shortcoming of insufficient hue contrast, it is generally necessary to use a small area of contrast color or brighter color to embellish and increase color vitality. 4. Medium color difference: the hue difference is obvious, and the contrast is bright, lively, warm and full. Pay attention to the change of lightness and purity when matching colors; 5. Contrast color: the color difference is very obvious, the contrast effect is bright and strong, saturated, gorgeous, happy and active, but it is also easy to produce a sense of disharmony. Pay attention to the purity change when matching colors; 6. Complementary color: The contrast relationship between one primary color and the other two primary colors is very different, and the contrast effect is strong, which is easy to produce dazzling, noisy and dramatic effects. Pay attention to the change of purity and area when matching colors. When using the same color, adjacent colors or similar colors, if the tone is dull and lifeless, then the color effect will be improved by appropriately borrowing the power of complementary color contrast. Fourth, purity contrast purity refers to the brightness of each color. Purity plays an important role in emphasizing the theme and creating various effects in color matching. High-purity color is irritating and impressive, and it is easy to get tired of making. Only with low-purity colors can it look exquisite, subtle and durable. High-purity color is easy to attract attention, and the change of strength brought by visual distance should be considered. V. Color Harmony The so-called harmony means coordination, harmony and integration, which not only includes differences and contrasts in hue, lightness, purity and area of colors, but also achieves the beauty of harmony as a whole. Not all colors will give people a beautiful feeling, and colors without uniform tones can only be over-stimulated in the visual senses, resulting in a sense of disorder without subject.
