Original image effect, early shooting quality is good, thanks to the source material.

Figure 1

I believe there are other ways to achieve the same effect using the Lab channel processing effect diagram. But by contrast, lag channel has the most powerful color latitude, in the deployment of color has a greater advantage, this method is quick and easy, the entire process is only three minutes.

Figure 2

First step: Convert the RBG mode to lab mode. Learn to use channels to deploy color, is to get rid of many color problems puzzled by a clever way, but also many experts in the color modulation on the secret of one of the secrets.

Figure 3

Step Two: Feel the original picture is relatively dim, so first of all the picture, I used the lab on the "A Recruit brightening law", if not too clear friends, you can see my writing this post, this step 10 seconds to complete, and then appropriate to adjust the contrast of color order.

Flatten the image, oh ~ ~ Photoshop Chinese Translation Sometimes very messy, the name is sometimes not the same, hoping to be more formal, more accurate. I like to introduce some small common sense in the post: Everyone in the process of doing the diagram, the two sides of the tool panel is very obscure view, can not fully observe the effect of the screen, sometimes really annoying!

Introduce a tip: you click the TAB key, the tool panel disappears, then click on the back. It's very convenient for you to observe the picture at any time.

Step three: Press Ctrl+1 (lightness Channel shortcut key) you will see the gray "lightness" appears, and then use the mouse to select "image-Application Image", then the application of the image of the dialog box.

Perhaps the Masters will think I introduce very long-winded, but for the first to the PS friend, such detailed introduction is the best textbook, so I write very carefully, take care of beginners.

Here forgot to write a sentence, after merging the image, want to copy a layer copy, this is for later modification must step, don't forget yo!

Channel (C): Select "a" channel; blending mode (b): Select "Overlay" to do so to increase the screen permeability.

Figure 7

Fourth step: Press Ctrl+2 (a channel) data such as diagram, you know, a channel color information is mainly from red gradient to green.

The main purpose of this is to the original image of the red gradient to the green color for a 100% overlay, that is, the original image of the red to green color information increased by one times.

A channel red and green, can not simply be understood as only red and green, it refers to include a red gradient to the green color process of a series of complex colors

Figure 8

This is the color of a channel 100% superimposed after the effect, we can see through the histogram and screen visible, from the red gradient to the green color information than the original image increased by one times, the screen color began to become active.

Figure 9

Fifth step: Press Ctrl+3 (b channel), still like a channel, increase from yellow gradient to blue color information.

Lab mode is the most important mode in Photoshop, it does not rely on light, nor ink, make up for the RGB and CMYK two color deficiencies, it is dedicated to color adjustment and conversion, in the adjustment and conversion process, will not cause any loss of color, it does not depend on equipment, So you can maintain consistency on any display.

Figure 10

This is the upper amplitude to a channel superposition foundation, to b channel superposition information one times after the effect, we can see, the picture color basically achieves the natural state when the photograph is taken. But photography tends to be a little more beautiful, so want to beautiful up, still have to add processing, put some msg tune a tune flavor.

Figure 11

Sixth step: On the basis of the previous, we will again to a channel "overlay" treatment, see what happens? There is no fixed procedure for processing pictures, the same pictures can be processed into different effects, nothing is best, as long as the likes is good. But the picture of good and bad processing also has two recognized standards, one is in line with the technical production standards, the second is whether the public love can also be used as a standard.

Figure 12

This is the second superposition of a channel after the effect of the graph, the picture has been quite beautiful, and did not produce color overflow phenomenon, this is the use of color levels, hue/saturation and other tools to adjust the phenomenon is difficult to avoid, this is the use of channels to adjust the advantages of color, but also the means of deep love experts.

Figure 13

Seventh Step: Choose b Channel again, but this time need to pay attention to, because the yellow increase too much will make mm skin is very difficult to see, so I chose in the mixed mode "soft light", in the opacity adjustment to 80%.

I feel more suitable for this choice. Of course, you can also try different blending modes and transparency, as long as it feels right.

Channel and application image, is the subtle essence of the adjustment picture color, this pair of good friend's combination, will deduce the ever-changing tonal and the effect, very magical, later I will also make the introduction.

Figure 14

I personally more satisfied, but friends feel green some too bright, hoping to reduce the brightness of the green some. All right, let's go. "Add layer style," from a whole bunch of menus, select the "Blending options" dish.

Figure 15

Step eighth: From the blend color Band, and then select a from the two options in A and B, this is because a channel contains green, and I need to adjust the green, the reason should be clear? (later you want to adjust that color, you choose the appropriate color band)

Figure 16

Step Nineth: Notice the two green strips? Adjust the above one. Special note: With the mouse to the small black triangle down to the middle slowly drag, at the same time eye attention to observe the screen, green brightness also with gradually lowered, to my mark 1th after stop, press the ALT key do not put, with the mouse carefully live small triangle right, separate continue to drag. The green tones will be smooth and harmonious, and will not appear stiff.

Figure 17

Tenth step: Now from Lab mode back to RGB mode even if basically complete. Now you can use other tools to do some simple fine-tuning, I believe everyone will do. I've lowered some of the green's brightness a little bit.

Summary: Using lab channel for color adjustment, to maximize the hidden color potential of the original, the biggest advantage is the color of natural harmony, will not produce a serious color overflow phenomenon and dazzling color separation, it is worth recommending and use.

A few words of mind: There are several publishers are about me in recent years, some of the tutorials compiled into a book, this said a lot of content can not write, that is not very stupid? But I think of the enthusiastic encouragement of my friends, think with friends all over the country together in the Forum of sincere exchanges and bring happiness, so decided to continue to write down. Not to show off, the second is to exchange my experience in learning, but also to learn the friends can clearly understand.
