Guys in this lecture we are going to look at the subtractive category which is very important that's
open the composition subtractive.
And here I have the video.
And you notice we have two videos one behind for the clouds and one in front.
That is the ghost but the ghost video first of all it's a motion graphic video.
Now the mods will work for you for any video if it's motion graphic or if it is you know normal video
shot using a camera go.
So I want to eliminate the white here or I want to eliminate the white collars.
It just makes sense that I darkened the video until the white disappeared for that.
Of course we are going to use this subtractive category.
Let's try that.
Now that has worked very nicely.
Let's pull it off and look at it again.
We notice here the colors.
It's dark here.
If if I do.
Now this is a bit somehow the same color but the change a bit but the whole white area has disappeared.
This is the major role of this category and it's important that you learn that because sometimes you
will be bringing PND or pick images and you want to remove that white that that is behind them so you
don't have to mask all the way you can just use this blending more.
Let's try and multiply this with multiplied the colors here and becoming darker.
They are getting nearer to the original and I like that that's better.
But I have a line here that is appearing I could fix that line by putting a big mask just a square mask
around the video.
And then this line will disappear.
That's one way to do it.
Let's try colorable not the same but you're not is now.
The colors here have really been darkened and a blue is appearing.
So mixing the greenish colors that we have in the ghost movie with the clouds here and to the gray.
We have something like is blue.
There is nothing you can do about this.
We can't change it to go to a classical liberal which is the same almost.
And you can change Jew Lindenberg now we have here a better image somehow.
The gray appearing even more and this mixing better with the cloud.
The nicest it will be a darker color not is that the video here of the ghost is becoming lighter.
And you know it's mixing more look at the bluish here.
Let's go back to the best one which is multiply here because I can see the gray everywhere.
So this is the job or the first job of the subtractive category.
Let's try another example and put these two off and open the shy and you put this image on.
Now this is a very beautiful image.
Let's note what's happening in this image.
First of all we have some dark colors all over.
That's very beautiful.
And we have some bright colors here or light colors that we want to change for example and give it another
on yours for the picture you know change it all together.
We can come to the background here.
We have a background that put a bluish background.
What happens if we add here multiply and it is what's happening.
All the white colors all the bright colors disappear and the picture has been darkened using the background
colors which is the blue.
If I put another kind of background color on the other things would have happened.
For example I don't know if we can get this one.
Let's try this.
OK.
But this one will crack the whole picture all together and it's quite something that you want to use
them.
Maybe you can open the opacity reduce the opacity for this picture in the background picture.
And here you are you are playing with it and is giving you this you know marvelous effects that you
can really not get anywhere else except of course in Photoshop.
Fine.
Let's do this one.
And here we turn it into a brew.
Let's try and for the guitarist Let's try the darker colors and look what's happening here.
The darker colors we went extreme and some colors really disappeared and the sky now is blue.
What disappeared is all the light colors.
Notice how his hand was white.
Let me remove this one.
Call this the white here.
The brightness on the hand is the brightness here.
And when you pull it back you see have all disappeared.
So this is very interesting.
So the way to work is to come to your image and decide exactly what you want to remove.
Do I really want to remove the wider area and darken the picture or do I want to do it the other way
or do you see that in the next lecture.
So here you are you have changed them.
Let's try something.
As for example the caliber nice effect beautiful effect.
In fact you have changed everything in the image.
Of course this has its own use not that you cannot keyframe the moment of course.
Now let's go try another example I won't show you here I have a very beautiful photo.
This is the lady looking up and it's all bright colors.
So you might think that OK if I darken this I will get rid of this white actually not really.
If you look at her face and you look what she's wearing.
It's all white.
So if you try to darken it what will happen is all the whites everywhere or the light colors will disappear.
There's light in the clouds with the clouds.
But at the bottom underneath.
And we have here darken or multiply.
And that is what's happening here really.
Not exactly what we want.
OK.
Unless this is what you want but this is not good because look at the face.
What's happening here.
The Glee song is not good.
Let's try to darken it.
Well that's much better.
But now we have some areas that are very funny.
So it's not like because you have white you can play with the multiplier.
You must study your video and your images to really guess what kind of blending will work.
And if blending works for you and for the two videos that you have.
Thank you very much for listening.
This was about the blending mode the first blending mode which is the subtractive category.
I'll see you in the next lecture with another category.
