Today, we will bring you practical techniques to adjust the skin color of portraits, whether it is portraits or environmental portraits. correcting the skin is not only the basic skill, but also the key to the quality of the work. Therefore, it must be mastered.

First of all, let's talk about the four elements of transparent skin color:

1, moderate exposure: there can be light and dark contrast, but not all are bright, or all are very dark.

2, skin color restoration: we have an inherent understanding of the skin color in our minds, so if the skin color is obviously partial, it will naturally be very uncomfortable.

3, remove local noise or blemishes: sometimes there will be local color patches, glossy or acne pimples on the skin, and this should also be repaired.

4, skin color and ambient light match: skin color must be affected by ambient light, so under the premise of natural effect, appropriate bias to ambient light hue.

For specific adjustments, please see the following detailed demonstration:

(this demonstration is only part of the whole revision process of this work, and only the part of skin color adjustment is demonstrated.)

This is the comparison before and after adjusting the skin color. Figure 1. Overall exposure adjustment.

In the basic exposure adjustment item of ACR, the dark part and exposure are brightened as a whole, so that the dark details of the picture can be restored, because only when there is light, there is color. When the exposure is normal, we will know if the color is accurate.

Take a look at the comparison after this step, as follows:

Now the overall exposure is basically OK, but the skin color is obviously dark and yellow, which is a problem that exists in most portrait pictures. So let's restore the color of the skin.

2, the skin color was originally said to adjust the tool: HSL (color mixer), because this tool is divided into color channels, management of the skin color channel, that is, "red, orange, yellow" channel, this is a general method! Everyone's portrait is applicable!

HSL tool, you can adjust hue, saturation, brightness, that is, the skin's color bias, freshness, brightness all-round change.

As I just said, the skin is dark and yellow now. To solve the problem of "dark" and "yellow", in the HSL tool, first solve the problem of yellow, as follows:

Choose "saturation" to reduce the saturation of the "red, orange and yellow" channels to reduce the skin color.

The comparison before and after the adjustment of this step is as follows

To solve the "dark" problem, as follows:

Choose "brightness" to improve the brightness of the "red, orange and yellow" channel, which increases the brightness of the skin.

The comparison before and after the adjustment of this step is as follows

3. Remove local noise or blemishes

The highlight of the model's nose is too hard because I used LED lights to make up a little positive light. We use the method of coloring a new blank layer to reduce the local highlight or gloss.

Press ctrl shift N to create a new blank layer

Choose a straw to absorb the normal complexion around you.

With a brush, choose about 15% of the opacity of the brush and apply it carefully in highlights or oils.

The comparison results of this step are as follows:

4. the matching characters of skin color and ambient light are all in a certain scene environment, so when adjusting skin color, we should not only focus on the skin color, but also synthesize the ambient light, considering the influence of light on the skin color, and under the premise of nature, appropriately let the skin color be biased to the ambient light color.

Here we will introduce the curve tool. The curve is a very fine color adjustment tool, the precise use of the curve is to click on the "drag hand icon in the upper left corner", rather than directly pull the curve.

This is to adjust the brightness with the RGB channel.

This is to choose the "blue channel" to reduce the blue appropriately, which is equivalent to adding yellow, which is more in line with the ambient light hue.

At this point, it will be adjusted!

Let's take a look at the comparison before and after the adjustment:

I hope it will be helpful to you. Thank you for reading.
