Hello there in Welsh

In the next video we're going to start getting into denoising and retraining at college

It started took a little bit more about exactly

The first thing I want to cover is what exactly is the day

Between

Because you may have heard these terms

Entity

All the concept behind both of

Is pretty

It's random imperfections in your

Between

Is that rain comes from film star

Annoys comes from digit

Brain is generally thought to be more than that

Pleasing

Because that doesn't break up the image into

Red green and blue

It's sold

Luminous

You can see Anna Wright

Noise on the other hand

Has varying intensities of your range of powder

The red

It also doesn't feel quite as you're getting

Which is another breeze

It's not

Regardless of if you have green or no

Terms are interchangeable

And we will be approaching them in the same way

So as composite

What do we need to keep in mind

When looking at green Earth

Are there really two major

The first is that

Any compound

Element that were

It needs to have green applied that matches our original

And what do we mean by match grey

Or looking for these five

The first is pretty

You want to make sure that the greater adding isn't 2 and 10

Or Tucson

I need the blind with the fridge

And this is tied and closely

Luminous

What exactly does luminous Curve mean

Well brain is not uniform

Applied across

Typically

Your blacks and your dart points are going to have significantly more visible Green

In your highlights

Is because a couple reasons in digital cameras that means that less light is reaching a sensor

And so more rainy day mistakes and up

Ending a break areas plenty of data is getting there and typically not is noise

Another reason is

Humans are much better at seeing the differences in contrast

In dark areas as opposed to very low

Areas

And some matching your luminous Curve

Is very important looks like a brief look at the exam

Is green uniformly applied across the whole image

The luminous curry Bazaar

You can tell it looks a very strange and now let's go to the properly applied luminous

Not see everything a City match

I'm using the exact same green

Between these two

Only difference is I've turned off are luminous curve in the wrong

The next thing we're going to have to keep in mind is the size of a

We need to make sure that were match in the individual that call them particles

Between our elements and our

She don't want to

Too big or too

That's pretty soft

The next thing is that green can come in varying levels of sharpness or softness

He asked me to make sure that matches

And

Define thing is matching the irregularity in the

In other words matching the general pattern

Of the grain structure

In general this is as much of a problem with modern day digital cameras because

The census have

Pretty good there's not a lot of pattern

The noise is pretty uniform

So does the five keys to matching

Over practically matching green with bees in the next video in nuke but I just wanted to briefly talk about

I can't say

Let's move onto the second way that Grey

And that is

Brian May need to be removed from RL

1 of 2

The first

Is there

The green under ellum

Either isn't moving or doesn't matter fully

So we have to remove the grain and then reapply

Correct

And the second

Is that removing Green

Can help some of the work that were doing

Be much more precise especially when you're team

Let's take a look at an example key

One side is the ground and the other is

So here we have the alpha of our key and as you can see on the right side

Green is less than 40 we're getting a lot of chatting at the Edge and that's a very common when you work on

Once you remove all the noise you can see on the left that's a very smooth key there might be a tiny

Bit of chattering but it's much more settled on the ridge

Whenever you're

And that sums up what to keep in mind

When you're looking at great

In your footage

As long as you're following this principle

You'll be set a girl green is typically pretty black and white cider

And was very important to keep in mind

Is there just because you're using the exact same camera as another

Does not mean that your green or be similar green varies greatly under different lighting conditions

Depends how the camera setup is it daylight

Are you Saturday night scene

It really depends so each shot

Should be approached as if it's a brand new grain structure because you will see diff

What's go ahead and move on to the next video put these concepts

Interact

Thank you very much for listen

And I'll catch you in the next
