This color map some friends feel difficult, I checked the RGB channel basically no big problem, we can use Photoshop curve tool to solve the color deviation, the reason is that the curve than the use of other tools to adjust the school more efficient and faster.

Many friends feel that the Photoshop curve command is difficult to grasp, I also saw some friends with the effect of curve adjustment, indeed most of them are not ideal, the root cause where?

The curve itself is extremely accurate, controllable range of the most widely, adjust the speed of a very fast tool, if you want to engage in the image of professional editing or to the studio to engage in professional later, that every day will face a lot of need to adjust the picture, you must be extremely fast efficiency to complete a great workload. So you must learn to skillfully use Photoshop curve tool, and the curve of the "beautiful Snake" mixed very well.

This chart is unlikely to give you a full grasp of the Photoshop curve commands, but it will give you a glimpse of the charm of the curve. But this is not the most important, the most important thing is to let you correctly understand the use of the Photoshop curve must be mastered by the prerequisite, related knowledge and principles introduced in succession.

The following is an example diagram adjustment process, through the case we can learn the PS curve tinting technique.

(1) According to the RGB composite channel of the principle of total color and color wheel relationship complementary law, select the blue channel and determine two anchor points, evenly down, the goal is to reduce excessive blue and increase the same amount of yellow. As shown in Figure 1.

In the adjustment of the curve, there is a problem of beginners, that is only red, green, blue three channels of choice, seems far less than color balance intuitive and rich. In fact, the principle of the curve and color balance is the same, increase or reduce a certain color at the same time, it will be equal to reduce or increase its inverse color (or called complementary color). The color of the color wheel on the relative 180 degrees is complementary color. As shown in Figure 2.

(2) Now select the red channel, to determine an anchor point to pull up, you can observe the color of the screen began to become normal. As shown in Figure 3.

But the character's face tends to magenta, which can be clearly judged from the contrast of the color wheel in Fig. 4. If you are experienced in color, do not look at the color wheel chart can be accurately judged. How to correct the bias magenta or look at the color wheel map. Magenta opposite is green, think about the inverse color principle--to??? Travel Xian na 窬 strider to lie down? Minute Fly PHLC?/p>

(3) Choose green channel, slightly upwards, see Magenta eliminated, the whole picture color basically normal. As shown in Figure 5. This is the advantage of using the curve. I've been transferred here less than 10 seconds, and as you become more and more familiar with the color wheel, you can certainly reach this level. It's not a very difficult thing to do.

Now I am still somewhat dissatisfied with the color of the screen, but the adjustment to here, the remaining small problems have been easy to solve.

(4) In the school color, do not forget to make full use of black (black), White (white field), Gray (neutral gray) three important school color tools. They are used to bias the school.

Click on the black straw and click in the picture where you think it's darkest. As shown in Figure 6.

You may find that the screen is beginning to color, it does not matter, continue to go down. Click the White straw and click the Correction white field in the picture where you think it's brightest. As shown in Figure 7.

The black field and the white field are important basis for determining the shade and tone of the picture, and also an important tool for correcting tones. After the reset of the black and white field, the tone of the picture began to become clear.

Now the most important neutral ash settings are left. The more accurate the neutral gray point is, the more realistic the color of the image will be restored. In fact, in practice there are many ways to find neutral gray point, need some accumulation of experience. When you think the click is inaccurate, you can press Ctrl+z to undo the operation, and continue to click where you think it is neutral, until the screen color is normal. As shown in Figure 8.

(5) I still think the beauty of the skin slightly yellow, but this is not a partial color, but in such an environment when shooting will inevitably be affected by the reflection of the surrounding color.

Once again select the red channel, with an anchor point to rise slightly, the beauty of the skin become rosy, as shown in Figure 9. I like this kind of healthy complexion. Color is both objective and subjective, everyone will have their own different choices, as long as they do not deviate from the general direction, I think are correct.

(6) Further adjust the color order. As shown in Figure 10.

Transferred here, I found that the green leaves some yellow hair red, it seems not very spirit. Maybe that's the way it was when it was filmed, but the people we're doing photography always want to make it more pleasing to the eye. In this respect, artists and photographers than those so-called "school color experts" to be sharp and clever many, to fully believe your vision, do not let those data tied to your free creation.

(7) The use of color balance to increase green leaves of the cyan is a good way, as shown in Figure 11.

(8) Of course, you can also use the "optional color" command to make the skin of the beauty of the cyan reduce some, it depends on your own preferences. As shown in Figure 12.

Photosop has so many tools in place to give you a variety of options. If there is a rule that you can only use a tool to color or color, I am sure that the person does not understand the purpose and purpose of Photoshop.
