Back

In this video steps beginning or shot to final by adjusting optical lens effects

I'm tweaking a few of those tech issues that we can have

Let's get started

I want to do as I want to figure out what is going on with atmosphere

Difficult of a fix is this like you and or

Ahead and take a look at because that issue is likely in our atmosphere

And what's just check out the Irish VAT for cos that's where this light is

And you can see what's happening as we go from from 171 172 for some reason this is so

That's a strange issued a hair but it shouldn't be too hard to fix

Just make a

And do is just going to freeze frame

72

To you and Renee copy

Must be on frame 171

Ahead and make a shuffle mode

Wallpaper into our frame hold

And what we want to do as we want to copy

RGB 80 fault

Enjoy your party by 80

And we'll make sure driving is from input

Answer now let's go to the bottom on frame 171 and this looks like we'll go to our

Mummy zoom and we can see that are spotlight right now isn't a line if you get forwarded

It is a line but it's not tracked

We could projector but this is just one single frame so easy enough just

Move it in the policeman you take world 24

So let's just shifted the couple pixels it to make sure that

Nice and light

Corsa that was fully close

And

We could do and I see this

What is b consider keyframe on her disabled here

And then

Turn it off

And then that was essentially make sure I'm only copying over on one frame

This is a little bit dangerous to do

Animating your disable

Because what happened if you turn this off and on a review for

Is wrestling a Keith

And that's a very very dangerous because disabling is the main way of kind of troubleshooting

I'm checking if things are working

Necessarily know that you're setting keyframes if you don't have the new properties open because one this is closed

We don't see your keyframes here

So I don't like in a meeting or disabled with hard to be friends

Go ahead and get rid of this

What does abas enabled and I much prefer to do

To use a switch

American scooters over

We can use this

As a separate note whose sole purpose is to essentially disable The Shuffle

Can I accidentally add any keyframes doing this

So what's that a key

72 input 0

Then I go to frame 171 and say be wanting for one

And now it's simple enough we can disable this shuffle we want if that comes up for any reason and relax

Any accidents

So that should have worked

Shakira

Distract in

Correctly

That was pretty straightforward

And so in here

Another thing I am not the same as we do have lines over our spot like that

In here I think that's because in our explosion a room

Down here

It's not been blocked

Fire spotlights that something were going to

To fix

I've got a head

Disconnect h free render

The fix this we can just do an ad

Enable ad

Explosion

Change that to b

And it's still not appearing in search troubleshooting this and see exactly what's going on

RGB explosion alarm here

Select that and we see that we are blocking it

Let's just keep travelling down or a pipe and figure out what's going on

I'm looking here to solve xcaret

User problem

Have I reduce noise and it's not getting updated explosion

And I'm going to go ahead and just write out a version 2 of this

And I just use a pretty cool shortcut

When you have a right or Reno selected if you hit upper down that will auto version of Madame to file

In that

I'll make sure I label this

Reduce noise

Make sure to include this in elements for this week's class and I was going to rain

Really quickly

That's fine shop now let's go ahead and bring in Our Version

Nice and denoised let's just check it down here

Bottom

Call Sally have this blocking bellissima channel active line

We could add some but I think it's fine or not seen any

And now let's move onto when's effects down

So first I want to add some chromatic aberration to this

Meant to be based on a real shot

And one of those in week 4

Something to go ahead and

Open

Are we going to grab the schematic

Because we've managed to put a tree know about it based on reality so we can just copy and paste between Express

Throw it in here

FreeCell

Colour shift this isn't going to do

808

Start in our lens effects video

Darker foreground objects with you get more light bleeding especially

Purple chromatic aberrations go ahead and set that up really quick

Sore throat down the Kieran and the goal is to use this to try to isolate

Parts of an image so we'll just this

Something kind of like this

And I'm going to make an a road

Just affecting our

Fastest eroding advert ever

10 pixel

And I'm a rolling out because I want a chromatic aberration to wrap around the circle Jackson

Inner alpha channel

And I'm going to make another operation

Copy and paste vs

And this I want to be a bit more I want to see some more noticeable

Shifting happening

Just asking

Should we get there

Little bit

Colour shift in the brightest areas

This is probably too much right now

Think I'm going to

Back song

1

But you do see your breasts

Too much

Something like that

But I do think it's really going to

Sausage

Right

Operation

Operation

Next we can start adjusting or lens distortion I shot a grid

That has a similar focal length and similar

And we know

How to work with this phone

When's distortion

And we can go home

An analysis

And you'll see the results you're pretty one I think it's getting confused

Line on a keyboard

I took a picture of my Mum for this so the actual pixels foreseen

Go ahead and clear all of this what we can do is take control

And then we can hit reset and delete

And what I want to do is preprocessing

Maybe we can

3

Just want us to automatically work and then we can work this out

The try to get rid of those

Why was there

And then we can restart the mess

About the same amount as this

What's go ahead and automatically detect Airlines now

That's much better

And see what we get

Exchange this to read and that's just the way down

See what happens when we connect our minds the store

We can go ahead and zoom in a little

And so hard to read right now let's go ahead and it just number in Ark

And we can see it

Pretty Little Liars actually stretching this out words

And that's because there is really two types of ones distortion that you'll see

Destruction it Ben

Anna's pincushion distortion which bent outwards like this in this example once I was using has pin

Ashley stretch in a little bit

So we can go ahead and just grab this

Play secure

And it's pretty sad

Is stretching that's a serious

It is fixing the issue over there we are lucky we don't have to do any more work on there

No I just have a little bit more realistic distortion on mess

Intercession all taken care of

What's got a head and start working at now

I'm going to do and go to

2 elements

And that's bringing out

What age

And our denoised footage

Because they're what's the easiest version of the Alexa

Weak to Steel

From the shop

So what we can do as well

Screen

Play in here

What's a head in Analyser cos

And weather

To scatter

Use the crane surgery

What's the head and take over

Just getting some real windscreen over the help if you're bit more

But you'll see some stretching happening here

Elements to be the same format size here because there

A little bit

Shorter

We can just make a reformat

And even out stretching at the top of this what kind of been fine

We just need to make sure you look here that were picking the

Area

And now this is properly scattering all over her image

Image for short at night and would be presumably

Let's go ahead and jump

That's gonna cheat in

Call Sinatra just found some more

And applying a luminous it's not affecting are based on reality

We can compare with our approximate Green

Green is just a little bit softer in which is what real Grinch

If you don't have any news

Match between these two here

Hope this and see what we have

Between

What age

Rape ever footage on the right in Dartford

And what I want to do

Is first on trying to match the scene and make sure

Individual channel we definitely to Lower Red intensity

B

A word

Matching pretty closely

Channel now

Green she was a bit too

10

Probably size that attaches world is way too small

Intensity here

Find a flight that go ahead and check her other areas

Down a bit

So down here

Channel mask pretty well

It's not matching curtains the quick rack

Takeaway

Fixing desk

Newman a bit here over

And as we do that we want to bring this point in just so doesn't

A match

Just start

Wrekin maths

Try to get that follow

Fuel

Because I'm ten city in our Shadows is now career

We don't really want to lighten these that much which we haven't because are blacks are controlled by this

Anywhere affecting the current area with this point and we got these pretty darn close

We just keep adjusting our red for check on the monitor

This actually work

This is a very fine to control your movements

What does automatically complete this for you

We can do it as well

We can go ahead check out our cream Channel now

This over quite a bit

What does shorten this

Handle doesn't freak out here if you want us to be flat

Penis over

Chequers Shadows to make sure we haven't touched those

Excellent

Check screen

Screen it looks like we could use a bit more brain

Subscribe to this point

Just start for me

Check MOT

Original it's pretty close actually

4

And started shouting

That's looking

It's a little bit too intense probably the same price as we have to go to the real or bring this point in

The trial of void freaking Eldar

School in

Down until the smashes

Check out our manager or money does need to cancel bring this up some

Call Michael that matches

Red

Remind me to make the CV

Bigger

Snap-on 10

May need to change the size of a pro controller too big now

What's 10 City

Things to use as just a bit

More time consuming

When you don't have dark screen

And we can bring me to highlight

Again

What does trying to make sure this is within the ballpark

Incorrect

The big thing we need in the sentence is to get

And that's a pity there

And so now I think

30 closest go ahead in attach or advanced screen and see how it's looking

Quite as intense as I would expect to see in a nightshirt

Just like we did with our Josh green we can up the intensity of this a little bit

If we are putting the screen on our original monitor shot we definitely would do that but since this is

Off on its own is ok then this just a little bit more intense

Stop the like this

Important another relative size of an element is correct

You can do this either way I meant used our screen because were we can use real Green I prefer to do that

And now we have Oliver optical elements

Last bit that I think we should talk about is defocus do we need to focus on

Because these trains are in the foreground

We do have a fairly long lens in the shark take away

75mm by 75mm calculator

Do a math to figure out

Where did the friends actually be out of

So we can find out exactly how far away are objects

We can work at our frames

Thank you later

And they should have a Daf pass Z

And this pics of value represents how far away or object is

In metres so right now the screen is roughly 687 m away

What does keep that number of mine

Write it down

187ml

Screen

And now that's figure out exactly

How far away

Just saying

Play down to actually

What's going on

That is a very very bright so it's difficult to see into the give this to

Really really

Alright 30

Free sample here we can see this is 1700 m away

For away

From our Focus

So the question is if this is a real shark or trains realistically

Out of focus

What do a little bit of maths

You can grab this depth of field calculator

And it does a good job of telling you

Let's would be Focus

So we need to first a camera that has a similar sensor size

2 Arcana

And I also aperture

Aka are horizontal sensor sizes about a 41

In here

Closest camera that I found two that I wish you couldn't put your own custom ones that you can

At the phase one p40 has a sensor size of about 44 mm

So that's pretty damn close

Then our focal

Is 75

And are subject

Distance

Is 1700 m

Homework at the result

Answer the main two numbers that we need

Right here is our depth of field in your limit and adjust the field for

Are depth of field near monitor is telling us how close objects can be to our plans without because

In other words

How far away from a focus point can an object be while still remaining acceptable is nice

It is telling us that

Checks better away from the camera

And 15 will be in Focus

And Sophie take a look at our cranes will see you there much further than 50 m

The week and conclusively say that they should not be defocused

You're not going to add any defocus to the cranes because after clearly it doesn't make sense

Go back to a calculator for a second

Let's give this defocus the best chance that has as we learnt in R&D Focus fundamental as you already app

Chapter field becomes smaller

Which means more Focus and even when we start to change the standard 1.8

Which is a small as this would get on your shooting realistically

18 m is the cut-off point for tea Focus so are prunes should still be tech

And now we have our lens effects and I will go ahead and the cell

And we can take a look at what will hopefully be our final shot
