Tutoriel [FR/ENG sub] Paint tool Sai : Lumière/Light - Duration: 17:53.
Hello (＠´ー`)ﾉﾞ, some people asked me to do a video about that, so
I am going to explain how I manage light, shadow and other things.
To begin with, I did a little orb to explain how
I work with light on my drawings.
To start, I do a first light source
which is here, and then the second light source
which is here.
Firstly, we work with the first light source in a drawing.
The one which will be the light and the shadow.
It will be around this part where will begin to work
on the drawing.
When you have your source of light, don't forget it, because
it's really important.
It will modify the ambiance and many other things on your drawing.
Here for exemple, with the first light, we see that it will come
around here, our light source will be here to start.
Then, it will devide
Obviously, the light doesn't work with only one colour,
it works with several coulours.
So here for exemple, I started with a basic colour like this,
and then I did some sort of colour gradient with many colours.
Like this, until we reach the basic colour of the sphere, and it gives
something like that.
Also, for that kind of colours, what I recommend to do
is to, for exemple : you have the ... I don't know how do we call that, the " colour slider "
for exemple ( we will start with a colour like this ),
try not to do like this.
Or only if you really want to go on simple colours,
directly going like this, so we will have at the end
some basic colours.
But I personnaly prefer to have less basic colours
and go to more extreme colours which have nothing to do with
the basic colour.
That is what I have done here.
For exemple here, with this colour, I directly went into violets
to try to find the colour which will match pretty well with this until I did some kind of colour gradient.
So here, we find a colour like this which will become a colour like that,
with red tones, and then we will go down, pink tones,
and we go into dark pink tones, we'll say it like that, and the we really go
into violet tones.
So this is for the first basic colours, with the gradient
that we have here.
Then, we have the second colour, the second sun, the second light source.
In fact it will depents. For exemple, imagine that your character sits on the grass.
If there is grass under him, it will be green reflects.
Here, it's more neutral, so I took neutral colours.
It really depends on the background, what is around your character.
For now, we will take the neutral colours I have chosen.
We will look at the main colour of the sphere, which is violet,
and we will slowly be going down
with more light colours.
Here it stays in the violet, but you can go in
blue tones.
Here for exemple, we can add a little bit of blue to give more volume to the ball,
so it will be a little bit like this.
Here it's kind of like the what we already did with the first light source,
we start with the basic colour and then we do a colour gradient with what the colour slider gives.
What you can also do with Paint Tool Sai,
( I say this but it is on other softwares as well,I think there is also this in Clip Sutio ),
is to use the modes.
The modes are kind of like filters. Actually they're not really filters,
but I think it kind of looks like.
You have your base drawing, so you open a new layer on it, most of the time
I use the Airbrush, which is here, and what you can do is simply to
choose a colour which will depends if you want warm colours,
cold colours, or totaly what the fuck colours.
Then you add a little bit of this.
So it will soften the base line we had, so if we look at the difference ...
Now it really looks solid, sturdy we'll say.
Because here there is still the line of the basic colour of the sphere, but
if we add a colour which more looks like this, it will simply
soften a little, and we will really feel the light coming
more naturally.
But this depends on the texture you want to have.
Let's come back on the modes. This is the normal mode here, but
what I often use in my drawing is the Overlay.
It gives something like this.
It looks like ... I don't know how to explain, but it will more fit
to your drawing, it won't totally kill it, it will more matches with it.
Then you have the Luminosity. This will " kill "↑_(ΦwΦ)Ψ your drawing, it will really takes the light you did,
but obviously you can play with it so
it will more be gross or not.
It will " kill " your drawing not in the way that it will spoil it,
it will just less take it in count, the basics line you had. It will mostly take
the like as how it is and put it directly on your drawing.
So there was the differences between Overlay mode and Luminosity mode.
We can use that for the back as well.
Also, what you can do with Overlay, is to enable Clipping Group :
it will force you to not overflow, purely.
For exemple here, I won't overflow at all because Clipping Group will make sure
that it will say on the lower layer.
So it will allows you to be sure to not overflow.
It's right here, between Preserve Opacity and Selection Source.
So what you can do with Overlay ( it's not only about light), if you
want to add shadow to what you are doing, simply use Overly.
It will darken.
It work in both ways : it can give you light as well as shadow.
It depends on the way you want to do it, actually.
Then there is the Shade mode, but Shade is a kind of like the opposite of Luminosity, at the end
it will " kill " your drawing, but only with shadow.
They are both opposites.
Next, I can show you how I did all of that on my artworks,
with Sara and Erwin, here.
For exemple with the light, but here he isn't an object, he is a human.
At Erwin's level, what we can see is this part here.
In this part, there will be light coming on it,
from there.
So it will come to Erwin's skin.
What I did here is to firstly his basic colour, and then I
added this " flashlight " effect you can do with Overlay or Luminosity.
For exemple you have the basic colour, and you have the " sub-colour ", which will be
the shadow's colour, and then the " sub-sub-colour " : its the kind of violet colour, which will
come, if I'm not wrong, here.
Its really light because it will helps the sub-colour which will
come on his skin, and pretty much everywhere here as well.
This, will be the sub-colour, which is not the natural colour, it will
be here to reflects the background on the character.
So, as I was saying, here there will be,
to add a little bit of a 3D effect, light orange tones, the " flashlight " effect.
By using Overlay, you have this effect here.
The effect will make the skin a little bit transparent, like when you stick a flashlight
to your hand, it will gives this little orange colour like this.
Or then you also have Luminosity, who will
do this less softer.
So all of this were for the exemples.
Also, about light, as I said about the sub-lights,
it's more on this drawing that we can see it,
also in the Kana artwork which is a little lower, it's that ...
( oops ) ＼(º □ º l|l)/
( ok, it's alright, phew ) ｡ﾟ(TヮT)ﾟ｡
So, for exemple with sub-lights,
what you can to with them, is to delimitate characters when
they are too close from each other, or try to delimitate them from the background so they show up more.
For exemple here, we have this there, there, and there as well.
It's a sort of delimitation.
And here we find this " flashlight " system which is here, or even
here on his skin, or here on his hair.
The " flashlight " system is not only about the skin, you
also can use it on the clothes, that's why sometimes with some artists
we see that they use orange for the flanges, or even on sceneries,
purely.
There, it's kind of like this as well.
Light is not only about white, it divides into serveral things.
When it comes to an object, it works a little like this.
( And it's crashing again ) ヽ( `д´*)ノ
( k ) (｡•́︿•̀｡)
About the Rui's artwork, who is on a wheat field, it's the same.
There is very powerfull light, so here I used Luminosity more to do this drawing.
The light is so strong that at some point that there is character parts
that we won't even see.
But it depends on the style you want, it depends on what you want to do with your drawing.
For exemple, on the drawing with Erwin, it's more soft, it more fits,
whereas here its way more brutal, we'll say.
With Kana's artwork, we can see that there is this parts there which are
more lighter because of the sub-light.
Now, I will show you the brushes I use.
I use around 5 brushes on SAI, but I will migrate to
Clip Studio soon, so I don't know how I'll do.
Here, you have the basic brush.
It's like, if you press softer, it will do fine traits,
and if you press harder ... it's basically like ink, I think
it's the basic thing.
But I didn't set the density to 100%, for me it's
86% because I like that there is this kind of thing where the brush
will be a little more transparent.
Then there is the base marker. You have the settings here.
The marker is more to directly " paint " we'll say,
mixing colours together.
It's the brush I use the most for the skin, it's more simple like that.
Then I have the same marker with another brush on it, this one is more to go in
the extremes, the brush will be more broken, less soft.
Then I have another brush next to that.
It's the same, but it's more to be a paintbrush, not to mix
colours, it's more to do things where I don't need to have
something below, I can do this how I want.
And same here, the density set to 35%.
It's really low, if I'm not pressing we don't see a lot next to the other one.
Then, there is the brush for the clouds. With this one, it's the same, you really have to play with it
to find something you like at the end.
Basically, to do a simple cloud, we take back these colours there and then
play with it and you will have a cloud quickly, it's pretty nice.
You also have the settings of it here.
To finish, the last brush I use to really harmonize everything, is Water.
I think it's directly on SAI, I never changed the settings since I use it.
This one is to make softer all of this.
For exemple ... this.
Basically, this is it.
It's for ... it's not like watercolor ? I don't know, I never did that.
It's more here to harmonize everything.
Instead of being broken like that ( This was a texture though ),
we can have something like this.
Ok, so I think this was all I can explain at the moment,
And I hope it will help you for your drawings ! (⁄ ⁄•⁄ω⁄•⁄ ⁄)
