WEBTOON Basics Daylight Correction
GCC Academy
Hello, I am webtoon artist Joomyung
It is time to learn about daylight correction using Clip Studio
Daylight correction is the most basic correction in webtoon correction
If you learn about daylight correction
before learning about afternoon and evening correction
you can do afternoon and evening corrections more easily
Then, let's learn about daylight correction
Transparent Pixel Lock
Let's start with daylight correction
Before we start the correction
let's learn how to adjust the tone of the painted light and shade
to suit the mood
by locking transparent pixels
This is how to change the light and shade color using locking transparent pixels
First, let's move the reference layer on the first pen touch layer
down to the base color layer
The way to move the reference layer is the same as when you applied the reference layer
Right-click on the layer thumbnail
and click Set as Reference Layer at the bottom
or click the lighthouse-shaped icon at the top of the layer window
And now, let's move to the light and shade layer above
Now, we will lock transparent pixels on the light and shade layer
Here's how to lock transparent pixels
It's the same as when you set the reference layer
Right-click on the thumbnail
and if you scroll down, you'll see "Lock transparent pixels"
Click on that
or if you look at the top of the layer window
At the fifth
click on the part called Lock Transparent Pixels
Then, in the upper right corner of the layer
you will see a small icon
that looks like a pixel lock
This means that the transparent pixel lock is activated
What is the transparent pixel lock?
I will show you directly
Like this, if I paint a layer in red
the parts other than the areas where the shading is drawn will not be colored
This means that
Except for the areas where the picture is drawn on the selected layer, the layer is transparent
So this means that it's going to lock all the transparent parts
So, except for the shaded parts that have been worked on
the transparent parts won't be colored
This is the function of locking transparent pixels
What this can do is
when you want to change the shade color, you can paint it with a brush like this
only the shade will be painted
You can also change it through the color tone adjustment
Let's open the color tone adjustment window
Go into the tool window edit above
and scroll down to see color tone correction
In color tone correction, press hue saturation brightness
The shortcut key is Ctrl U
This will open the hue saturation brightness adjustment window
If you adjust the hue
it won’t change because it’s currently gray
Right now, only the brightness will probably be adjusted
You can adjust only the brightness like this
but if you change the color and then adjust the hue again
you’ll be able to adjust it because it’s no longer a gray tone
This ability to quickly change the brightness to the color you want
is the function of locking transparent pixels
Then, let's choose a shade color that matches
the background and atmosphere well and paint it
Paint an appropriate color like this
adjust the hue for the detailed parts
and change the saturation slightly
You can change it to the desired shade color
by adjusting the brightness to some extent
Secondly, let's learn how to
change the shade color of a specific part
When we paint a shade like this
we paint the entire shade with one color
This has advantages in terms of convenience and speed
but there are cases where the shade color of a female character
each character
or bright clothes like this does not match
Here's a way to quickly change
the color of a specific area in preparation for such a case
Use the selection tool for the reference layer to grab the skin all at once
I will once again use the function called selection range in the Layer
Go to the tool window above
and click Layer
If you come down from the Layer
there is a selection range
at the bottom
Each of these options provides various options
and it would be good to explain them one by one
but it may be confusing for now
so I'll explain only what you need
This function separately selects only the shading
painted on the face in the currently selected area
I'll click on it
In this case, only the shading painted on the skin will be separately selected
In this state, you can change the color
by selecting a specific color, as we saw earlier
and through Alt Backspace
you can change it to the drawing color at once
or you can use the shortcut key Ctrl U
Hue Saturation Lightness
Here, change the hue to a color that suits you appropriately
and adjust the saturation or lightness
to change it to match your bright skin tone
Then, press Ctrl D to deselect the selected area
Then, it will change to a bright light and shade color that suits bright skin tone
You can change the color you want like this
but let me explain one thing here
There is also a way to access it quickly with a shortcut key
What we used earlier
was selection in the selection range
and the shortcut key is to press Ctrl, Alt, and Shift at the same time
If you click on the light and shade layer thumbnail
you will only select the light and shade color
You can change it to the desired color tone in this state
Daylight Correction
Thirdly, we will learn about correction using layer properties
Now, this is where
we will start the correction in earnest
First, let's create a new layer
We will move the layer to the top
This is because we will create a new folder
We will make the newly created layer a folder
You can access the folder by clicking the new layer folder icon at the top
or using Ctrl G
the shortcut key
Change the folder name to Effects
The layer below it
will be called Multiply
We will change it to Multiply
Just like the name, you must change the properties as well
We will create several layers
Let's create one, two, three, four, five, six, seven
Let's create it first
Then, from the bottom to the top
we will change the properties of the layers one by one
The layer above is Color Dodge
Let's change it to Color Dodge
Likewise, you have to change the layer properties as well
The second is Soft Light
Let's make another one with Color Dodge
And above that, Multiply again
Even if it overlaps, make it the same
And above that, Screen
Let's finish by making it Add
Add
And we won't start the correction right away here
If you come to the folder above
the folder property is set to Standard
If you set it to Standard, the correction won't work properly
So, let's change the folder property to Pass
If you don't see Pass, try dragging it up
If you drag it up, you'll see Pass
You have to change it to Pass to reveal the correction effect properly
Now that we've configured the layers
let's put them in a folder
and make the corrections
Let's start with the Multiply at the bottom
As I said in the previous lecture
Oh, here it is
I said we should paint the entire thing
in gray before the base color
This gray part is very useful
when making corrections
I'm going to apply the overall atmosphere to the Multiply
If you hold down the Ctrl and left-click on the gray layer
the entire thing will be selected
From this state, I'll go to the Multiply
and apply the overall atmosphere
After applying an appropriate color by pressing Alt and Backspace
I think it's a little dark
so I'll open the color adjustment window
and change it appropriately
I will raise the brightness slightly
to make the color a little brighter
Since it's daytime, it shouldn't be too dark
Try moving the color like this to see which color suits
I will work on a warm tone
because the background is a little blue
I'm going to work on making the character warm-toned
I think it'll be okay
Now, let's go up to the color dodge
and use it to give another gradient
The gradient is not a gradient that you press
I'll show you
We're going to use it to find brightness
To get the gradient tool, go to the tool window on the left
If you come here to gradient
use the transparent option in the drawing color
It's the most basic option
Let's just click here
What do you think?
It's too bright, right?
If you use it too brightly
the picture will look awkward and too bright
so I recommend using the gradient tool from a bit of a distance
Use it gently from a distance like this
The color has been added now, did you see?
Ctrl Z, Ctrl Y
Can you see the color changing slightly?
This is enough
And a little bit below
I'll lightly lay down a warm tone
I've laid down the mood to this extent
I think the gradation is okay
so once I select the airbrush
and use a soft brush
I'll lightly touch the part where the scarf is once again
and since the clothes are also a bit bright in yellow
I'll lightly touch the necessary parts of the clothes as well
Okay, this much should be good
Don't do too much
If you do, the picture can pop out too much
or the balance can't be right
This much should be good
I'll finish the color dodge here
and go up to Soft Light
Soft light is used to paint the area that receives light
You can use any pen brush
but I’ll be using the
Mixing Round Brush available
in the default "Thick" category
I'll paint it with a moderately warm tone
to see if it works
It seems fine
Let's go with this selection
Earlier, we mentioned that holding Ctrl + Left Click
on the base gray layer selects the entire area
You can lock it in this state as well
Now, lightly add highlights to find bright areas
Adjust the brush size as needed while identifying these highlights
There's no need to overdo it
Another useful tip is to use
a soft eraser
Lightly erase areas where too much color has been applied
to create a more natural look
For the skin
gently smooth it out with the soft eraser for a seamless finish
For the hair, focus on the bright spots
and smudge them a bit
Don't overdo it
You can use the scarf
using the reference layer selection tool
If you choose a scarf like this, it will be selected
If you try to make the size smaller, you can erase any parts
you think are awkward
And for the parts like the clothes, just a little bit
If you do too many bright parts
the picture can become a little awkward
and the texture of the clothes may not show up properly
If the bright part shines too much on each wrinkle of the clothes
it can look like vinyl clothes
Or, like leather clothes
Think about the characteristics of the material
and find the shading or bright parts
I'm zooming in and out too much
so I apologize if it feels dizzying for viewers
I ask for your understanding
Good
Now that we've finished with Soft Light
let's move on to Color Dodge
Color Dodge is used to brighten specific areas
I'll show you
I'll demonstrate it using a soft brush
Before it really shines, there's a feeling
that the overall saturation is a bit bright
I'm going to find those parts appropriately and paint them in
I won't do it too much
I'll just find the right amount and leave
Okay
I'll stop here and finish the color dodge
Next, let's move on to Multiply
This layer mode is slightly different from the previous Multiply
Here
we'll darken specific areas to emphasize shadows
This is often referred to as "pressing down"
Let me show you how it works
First, select the scarf using the reference layer selection tool
We'll isolate the shadows within the scarf and work only within that area
As I explained earlier
there's a method for targeting only the shadows
Select the shadow layer
go to the Toolbox Layer menu, and choose Selection Range
Then click Select, and only the shadows will be selected
Now, switch to Multiply
and we'll use a soft airbrush for this process
I used a soft airbrush
to capture the shading on the white
By doing this
I can lightly press the shading of a specific area like this
Similarly, if you select the clothes
and Ctrl, Alt, Shift, and click the thumbnail in the shading area
you can select only the shading like this
Using the soft airbrush, gently blend
and press down specific areas
This technique enriches the image and gives it a firmer, more defined look
After painting like this and deselecting the selection area
if you think you pressed too much
use a soft eraser to erase the areas gently
I think it's good enough
Let's finish the Multiply here
and move on to the screen
Screen can be used to create a glowing light effect
Let me show you how to apply it effectively
and achieve a radiant look
This will be a basic version using the screen properties
and the most basic method will be using a soft brush
I will select once with a soft brush
and select the color of the light appropriately
Then, I will paint to see
if the color of this light matches the part where the light comes from
Since it does not create overall light
you can think of it as light used on the person
The light used for the character
since the character is warm-toned
so I will also try to bring in warm-toned light
Select a warm-toned color
and do this gently
If you press too hard, a lot of light will come out, but it'll look awkward
So, like this
by tapping with a soft brush
you can create the feeling that there's light inside the character
The point is gently drawing the boundary between the shadow and the light
I'm not painting the bright parts
As you can see
like this
I'm painting the boundary between the light and the shadow like this
Like this
Lightly like this
Like this
And if it seems too much, use the eraser to erase it again gently
And you have to keep zooming in and out of the picture
to see it's going in properly
and not too much
And if you cover the pen lines too much, the drawing may look muddy
Please be careful about that
However, you can intentionally
cover the pen lines for a production feel
to create a new feeling
For example, there are parts like this where a lot of ink has been used
You can do this
little by little
You can change the feeling of the drawing a little bit
This is the most basic way to find light using the screen properties
Let's deactivate the layer for a moment
and create a new screen
This will show you how to find light
using blur and screen properties
Press Ctrl and select the entire base color gray
Ctrl and mouse left click
Then press Ctrl Alt and select the shading thumbnail
Previously, we only captured shading from the base color
but this time, we only captured shading from the base color
For this part, go into the layer
and below the layer
go into the selection range from the layer
Select from the selection range at the very bottom
This is an option to find only darkness
and if you press Delete in the selection range
this is an option to exclude shading and find only light
This way, you can paint only the light part
Now, let's press Alt Backspace
What do you think?
Right now, there's too much light in the entire area
This is because
the light has been included even in the pen touch
Press Ctrl Z again to go back
and now we will exclude the pen touch
If you press Ctrl Alt Pen Touch Layer Thumbnail
the pen touch is excluded
In this state, Alt Backspace again
If you do this, only the bright part is now fully colored
Then, duplicate the screen layer once
After duplicating the screen layer, let's go down
and blur this lower screen layer
Come to the tool window, filter blur
Gaussian blur
the range is 80 to 100
This may vary depending on the situation
so by pressing the preview
it's good for you to find the appropriate value
I'll give it about 98 or 100
What do you think?
It definitely feels bright
If you want it to be more blurred
duplicate the screen with this blur applied again
It's brighter, right?
This is too bright to be used
only for specific productions
so I think it's good for you to use it appropriately
depending on the situation
Go back by pressing Ctrl Z
Here, you can adjust the opacity
to adjust the glow
I adjusted the opacity
I've captured the glowing feeling like this
Now, let's go to the Plus above
and capture a little more glow around the entire figure
I think it's good to think of it as a bit of a halo
Just like this
And with a soft eraser, I'll erase more parts
that seem too much
Okay, that's it
And finally, I'll upload one more layer and create a screen
I'll create one more screen
What this screen is
it's not about the figure, it's about creating the overall light and tone of the picture
I'll go into the gradient tool
and choose a color that fits the mood
and I'll also lay this down
from a little far away
Okay
It seems a little too much, so I'll erase a bit
Okay
So, we've looked at the daylight correction
In this lecture, we learned about Clip Studio's daylight correction
Next time, we will learn about afternoon correction
Thank you
Transparent Pixel Lock Transparent pixel lock means Only the drawn part of the selected layer can be painted, and the transparent part cannot be painted
Benefits of transparent pixel lock You can change the brightness and shade of the desired area by painting with a brush You can adjust the hue saturation and brightness of the brightness
Daylight Correction Create a new layer as a folder and change the folder properties to pass through
How to Correct Multiply Layer 1: Apply overall color to the figure with a color that matches the background Color Dodge Layer: Apply gradient to the figure Soft Light Layer: Add color to the areas receiving light
Color Dodge Layer: Brighten the color of the layer and reduce the contrast Multiply Layer 2: Paint the light and dark areas darker in some areas Scree
Add Layer: Create a feeling of light near the figure Add Screen Layer: Create overall light and tone for the picture
