This one up and we want to explore the add subtract intersect lighting ducking and so on.
Push a faultless add on other mask so you can select the layer and using the shape tool.
You can now create another mask here.
I'm creating this mask just for demonstration.
I want an intersection here.
If you take the second mask and you give it subtract Heriot so it subtract itself from all the other
umask above it.
If it put a stop it was substract from all that is above which is the whole layer.
You know this is what happens Cathead is odd.
So the cathead is are good.
This is the concept of subduct.
It will just remove itself from what is about if you go for example to intersect so much will intersect
itself with all the above masks including the very last.
A third mask for example just over here you notice.
Now if I take my stool put it on top of my squad.
So mask one will intersect with all the above masks if mask is under it should not intersect just what
and was above.
So the lingering order is from top to bottom.
This book must go to it.
So now you are adding all the masks.
Not this one two three stick masks three and give it that for example it acting somehow like the intersect
but it's extruding itself also.
So Musk's too will act as intersect and exclude itself.
Again something like this.
Then you have the option difference for my stew it would make the difference between itself and all
the other masks.
So what's the rule of working here.
Well it gets very complicated if you start changing many of them here.
For example this one is put on.
And this one in a darkened studies like this.
So there is no general rule here but the concept is that you can and you can remove you can intersect.
You can Darkon.
That means removing itself and you can make the difference.
For example come and play around here.
It's very interesting and I'm sure you will get very confused because until now I get confused and don't
forget about the Inv. now.
So is this what will happen.
So really it's fun to come and play around with these attributes here and get used to them.
Thank you for listening.
I'll see you in the next lecture.
