Guys and welcome to this new lecture in this lecture I'm going to explain to you about the concept of
blending modes and how they work.
We just want to see the concept now we want to understand that the Algar is how they work a bit and
then we'll move on to categories in the next lecture first before we have a source layer that is the
layer where we will apply the more.
And then you have the underlying layers or most of the time you have one or two layers.
These are the layers beneath the source layer we call them the underlying layers.
So now when you apply I-mode to layer it uses the pixels all the colors of this layer where he applied
the more and all the pictures all the colors of the layers beneath our interchange pixel and color is
the same thing that you have a dot that's a pixel that has a color.
Let's take an example.
If I change the mount to something extreme let's say substract.
You notice how the colors have changed the colors of the source layer have changed but the colors of
the underlying layers do not change and nothing happens to the underlying layers.
And in fact this is just a mode.
So you didn't do anything to your video within your filing system.
So substracted is a mod that we substract the colors of the source layer from the underlying layers.
When you apply mode it will apply analogous to the layer the source layer where the applied the more
and using all the layers beneath.
And that's it as simple as this.
So depending on what you have beneath the source layer it means whatever it is the under lying layers
the colors of the source that will change if I take a different layer underneath.
For example as the clouds the picture and I put it here and remove this one you notice now everything
has changed completely because the underlying layers have changed.
So we take the pictures or the colors of the land where you put the movement and change them according
to the layers beneath the source layer for each mode.
You have a certain algorithm.
So that's the concept.
And that is important that you understand.
So substract does not work on this layer only it needs all the underlying layers to give you the new
colors.
Let's move on to the next lecture and learn about the different categories.
See there.
