PS teaches you neutral grey grinding skin

There are a lot of similar with Noiseware, the advantage is very convenient, pull a pull parameter can be, but the disadvantage is that this kind of grinding plug principle is to disrupt the arrangement of pixels in the skin, can not retain the pores reflect the skin texture and detail. While the high frequency grinding skin in the "surface blurred" while also destroying the pixel arrangement, but "high contrast retention" operation can achieve enhanced texture effect, and neutral gray grinding skin is completely do not destroy the pixel arrangement, rely on deepening the adjustment of light and shade relationship to wear skin.

The application and difference of the high-low frequency grinding and the neutral grey grinding skin: high-frequency grinding skin is more evenly used for face exposure, in the face of more uniform exposure, the main use of high-frequency grinding skin to solve the problem of rough skin or goose bumps, this method of operation is simpler but not suitable for high demand for commercial pictures. The neutral grey grinding method is suitable for high demand commercial pictures and is often used to repair images with wrinkles, scars or uneven face exposure when dealing with non-commercial images.

Today to give you a detailed introduction of neutral gray grinding skin method, first of all, to tell you the principle of this method.

First of all, the picture is two-dimensional, is a plane, then what makes people look like three-dimensional? and sketch is exactly the same, rely on the relationship between light and dark, that is, white, gray, black clever combination, usually the brighter part of the light is the highlight of the feeling is protruding from the screen, the closer The Observer. The darker part of the shadow is the impression that it is recessed, which is far more distant from the observer than the light portion. To give you one of the simplest examples, a face portrait, we can see that the nose is the most prominent, in other words is the nose than other parts of the face closer to the observer, this is because the nose is a high light area, both sides of the nasal alar is shaded area, the contrast between the three-dimensional. Therefore, the light and shade relationship plays a vital role in the stereoscopic and level sense of the picture.

Neutral Gray Grinding is the use of the principle of the skin to deepen the reduction of light. For example, how can wrinkles be seen? Because the skin folds hinder the light into the formation of shadows, you just fade the shadow area, wrinkles disappear, because there is no light and shade contrast, the use of neutral ash method for acne, freckle and so on are a truth.

The following is an example of an operation demo.

Neutral Grey grinding skin steps:

1. Import the picture into PS, press ctrl+shift+n new layer, layer mode to soft light, in the bottom column "Fill soft light neutral color" tick, click "OK" to build the layer.

2. The establishment of the black and white adjustment layer, the purpose is to exclude other color interference, so that the picture only black, white, gray three shades, easy to deepen the dodge. Click on this icon in the bottom right corner of the PS interface and choose "Black and white".

3. The purpose of the curve is to highlight blemishes on the skin, and some dark spots are more easily found after being pressed. Click on this icon in the bottom right corner of the PS interface and select "Curve".

Pull the curve to the right and darken the curve.

4. The left side of the toolbar to select the brush, wrinkles, scars, bags, such as uneven exposure of the area smear, if it is a high demand for commercial films, you should enlarge the image of the pores to smear, smear the time to adjust the size of the brush according to the situation, opacity and flow.

This method can also eliminate the face of the fat, can see that there is also because the local skin bulge caused by uneven light, so as long as the shadow area to reduce the light on it.

5. After the completion of the deepening Dodge, select the black and white adjustment layer, right-click, delete the black and white adjustment layer, and pull the curve to normal value (can be adjusted according to the actual situation), so that the grinding is finished.

However, there is a common problem with neutral grey grinding, which will be grayed out after the darker shaded areas are reduced.

Why Ash? Because of the time, in fact, is to increase the brightness, lightness increase too much, saturation will drop, so hair ash.

How to solve this problem? Let's talk about it.

1. Establish the observation layer, or the first step with the neutral gray grinding skin, pattern soft light, fill 50 degrees of gray.

2. Use the optional Color tool, in the optional color in addition to black, white, gray color black to the left to pull the head, and then black, white, gray three colors in black to the right to pull the head, and at the bottom of the check "absolute".

Then the image becomes like this

The darker it is, the lower the saturation, some ask why. Here's an explanation: just set up an optional color adjustment layer, which is actually an observation layer, we reduce the black, white, gray color (red, yellow, green, cyan, blue, magenta) in the optional color, which increases the lightness of these colours, while the less saturated areas are red, yellow, green, cyan, blue, magenta, So the degree of reduction is less than the normal area of natural and saturation, so the darker the lower the saturation. Then add black, white, gray in the black value, equivalent to increase the color and hue contrast, let us more intuitive to see where the less saturated (the equivalent of neutral gray grinding of the dark curve of the process).

3. Under the observation layer, create a Hue saturation layer (click Hue Saturation tool), reduce saturation by about 50%, then create a new layer (shift+ctrl+n), create hue saturation layer under new layer, increase saturation by about 50%, The two hue saturation layers are then reverse-masked (press ctrl+i).

Another would ask, why build two hue saturation adjustment layer, and one to reduce saturation of one increase saturation?

Take note of the details in step 3, we created a new layer in the middle, the first layer to reduce the saturation is created in the optional color observation layer, and the second layer to increase the saturation is created in the new adjustment layer, we will only be in the adjustment layer after the operation.

4. Use the Brush tool on the left side of the toolbar to change the background to white (press X) to smear in the black area until the grayscale is even.

5. After the smear finishes, the observation layer (optional color 1, Hue saturation 2) is closed or deleted.

Finally, this is the effect, is not the saturation of more evenly.
