Guys and welcome to this new lecture in this lecture I'm going to explain to you about the concept of

2
00:00:05,260 --> 00:00:08,350
blending modes and how they work.

3
00:00:08,380 --> 00:00:13,660
We just want to see the concept now we want to understand that the Algar is how they work a bit and

4
00:00:13,660 --> 00:00:19,840
then we'll move on to categories in the next lecture first before we have a source layer that is the

5
00:00:19,840 --> 00:00:22,550
layer where we will apply the more.

6
00:00:22,840 --> 00:00:29,130
And then you have the underlying layers or most of the time you have one or two layers.

7
00:00:29,140 --> 00:00:35,700
These are the layers beneath the source layer we call them the underlying layers.

8
00:00:35,710 --> 00:00:43,720
So now when you apply I-mode to layer it uses the pixels all the colors of this layer where he applied

9
00:00:43,720 --> 00:00:52,450
the more and all the pictures all the colors of the layers beneath our interchange pixel and color is

10
00:00:52,450 --> 00:00:56,450
the same thing that you have a dot that's a pixel that has a color.

11
00:00:56,770 --> 00:00:58,030
Let's take an example.

12
00:00:58,210 --> 00:01:02,200
If I change the mount to something extreme let's say substract.

13
00:01:02,230 --> 00:01:09,100
You notice how the colors have changed the colors of the source layer have changed but the colors of

14
00:01:09,100 --> 00:01:14,370
the underlying layers do not change and nothing happens to the underlying layers.

15
00:01:14,440 --> 00:01:16,890
And in fact this is just a mode.

16
00:01:16,900 --> 00:01:21,940
So you didn't do anything to your video within your filing system.

17
00:01:21,940 --> 00:01:30,080
So substracted is a mod that we substract the colors of the source layer from the underlying layers.

18
00:01:30,280 --> 00:01:37,880
When you apply mode it will apply analogous to the layer the source layer where the applied the more

19
00:01:37,870 --> 00:01:41,410
and using all the layers beneath.

20
00:01:41,650 --> 00:01:43,730
And that's it as simple as this.

21
00:01:43,930 --> 00:01:51,430
So depending on what you have beneath the source layer it means whatever it is the under lying layers

22
00:01:51,760 --> 00:01:58,050
the colors of the source that will change if I take a different layer underneath.

23
00:01:58,060 --> 00:02:06,010
For example as the clouds the picture and I put it here and remove this one you notice now everything

24
00:02:06,010 --> 00:02:10,920
has changed completely because the underlying layers have changed.

25
00:02:10,930 --> 00:02:18,310
So we take the pictures or the colors of the land where you put the movement and change them according

26
00:02:18,310 --> 00:02:24,350
to the layers beneath the source layer for each mode.

27
00:02:24,370 --> 00:02:26,870
You have a certain algorithm.

28
00:02:27,010 --> 00:02:28,140
So that's the concept.

29
00:02:28,150 --> 00:02:30,390
And that is important that you understand.

30
00:02:30,490 --> 00:02:37,690
So substract does not work on this layer only it needs all the underlying layers to give you the new

31
00:02:37,690 --> 00:02:39,010
colors.

32
00:02:39,010 --> 00:02:42,030
Let's move on to the next lecture and learn about the different categories.

33
00:02:42,040 --> 00:02:42,590
See there.
