Using computational lab to bring out the transparent and bright effect to beautiful photo photos

Swallows in the interview mentioned a lot of tools, such as "optional color, mask, white balance", there must be a certain portrait of the students on the basis of the late must have made perfect, one of the slightly noticeable swallow mentioned the key words

is the "overflow layer."

At that time I also outer, the "overflow layer" of the bibliography has not heard Ah!baidu a bit, a more relevant word is "the middle of the overflow light layer"

The so-called "middle of the overflow light layer", literally is specifically controlled by the middle of the "layer", that is, "mask." Through the use of various tools (such as curves, color balance, optional color), "middle of the overflow light layer"

can have a direct effect on the "middle tune".

What is the "middle tone"? Ask Baidu directly.

When it comes to the "middle tune", it is bound to associate "bright tune" and "Dark tune", where the word may be slightly not specialized, we can feel. and "light" related to a familiar word, called "high-profile", such as "High-profile Portrait."

So the two key words in the association, and the later style of the swallow, known as "High-profile portrait" to clean, transparent, bright and famous. Similar style, and the hummingbird on the humming, his film is more "High-profile"

Very, very, very much like a fairytale world.

Back to the actual topic, how to get the middle tune?

PS has a function called "calculation" (Image-> calculation)

Quote Baidu to know the original:

The so-called "calculation" in essence refers to the channel and channel between the "layer blending mode" to mix, resulting in a new constituency (the new channel alpha channel), this constituency (channel), is for our next operation,

Required, then the selection (channel) is called an alpha channel.

In order to get the "midtones", we use the "multiply" feature in "calculation," which is set as follows

Click on the "channels" panel to see the newly generated "Alpha 1"

Note that the red channel is selected in Figure 1, because we are dealing with human photos, of course, which channel is better to make, to be further examined, but usually the human photos to the red channel to do processing.

Another point to note is that in Figure 1 we have selected a "reverse phase". Similarly, we can use the "no reverse phase Check" and "Double reverse phase check" to obtain the other two channels, that is, "light" and "dark tune."

In fact, until this step, are not absolute, such as you can use other channels, you can use other mixed mode, specific discussion can go to the page mentioned above to understand

So, we get three channels, they are approximately represented in turn, light, middle, dark tone

On the left side of the "light" channel can be seen, the face, skin, models of white clothes, curtains and other highlighted areas in the channel is also highlighted, which indicates that these parts are "bright" area. Same

In the rightmost "darkened" channel, the hair of the model and the ears of the panda slippers are highlighted, indicating that these parts are "darkened" areas. With these three channels/constituencies, what are we going to do next? My first reaction was to choose color and color balance. Because of these three channels/selections, the optional color allows me to "tune" "Midtones" separately.

"Darkened" to color. Of course, I can also use the Curve tool, respectively, different levels of the tone adjustment

But what I'm going to introduce here is not an optional color, or that I gave up after I tried the optional color. Why? Recall that the swallow or the Chu-mad film, there are obvious lab space downward color traces,

Because those bright but full color in the RGB space is difficult to get, but in lab under easy. But some of the students who have a palette experience in lab will also know that lab a curve can be very straightforward

Very powerful purification color, but there is a problem, it is difficult to carefully adjust. For example, I can quickly make the whole picture yellow bright blue to bright, but I am very difficult to let some of these changes in the meantime,

The other is unchanged. Generally in the analysis of the Swallow's film, we are concerned about a frequent high saturation color block, but really hands-on lab curve will find that when this color block to achieve the effect, the other areas of the screen

The color may be very broken! So it is easy to think of the method of regional color palette, with the mask to solve this problem with small chaos. The "halftone adjustment" actually gives the possibility of another quick and easy to be portable .....

That's the use of the lab curve for the different half-tone. For example, I want the highlights to be transparent and bluish, so I can load a B-channel trimming curve while using the dimming mask, and this adjustment will not unduly affect

Other Half-tone. The theory is finished, and we see it for real.

First here is the original film, the right side of the curve after fine-tuning the film. Lightens the hair and gives the dark part a light.

And then we figure out three different channels.

Select image-> mode->lab color and convert to lab space for further adjustment

Into lab I like to first put the brightness layer, in the channel panel light "Brightness" channel, hold down the "CTRL" and click on the Brightness channel, get a selection, and then press "CTRL + C" Copy this channel,

Click "Lab" channel back to normal mode, select the Layers panel, press "CTRL + V" To copy the brightness layer

Select the layer, the blending options in the "color" mode, the opacity set to "20%" or so, this step is mainly to highlight the film, so that the film looks more translucent and bright

Then go back to the channel panel, light The ALPHA1 channel, press CTRL while you click on the Brightness channel, and get a selection, that is, a "bright" selection. Back to the Layers panel, select the Curve tool

And then we have a lab curve with the "brighten" mask.

The same method, the ALPHA2 ALPHA3 operation, gets three curves
