Hello everyone, and today we are going to see a situation that
00:00:04

It has happened to me that
00:00:05

when I started the photo shoot of the turbiritual, which
00:00:09

was canceled, and when I finished it, or when I had to
00:00:14

do some additional after having done the interior, it had cleared and had come out alone, then let's see how to replace this sky with another one
00:00:25

First I'm going to bring the sky that
00:00:29

did when I went up to the roof for example, where I have a fairly straight horizon in the middle of the photograph, then I will use the same real sky, although
00:00:40

we can have a bank of skies from other places that
00:00:44

may coincide in our project
00:00:49

In principle I'm going to drag the sky layer below the original photo, and the original photo I'm going to give control A to select all, control C to copy, and I'm going to give the
00:01:04

mask symbol
00:01:07

With alt, I'm going to click inside the mask, and with control v I'm going to paste the same photo
00:01:14

As you can see the masks are shown in grayscale, if we go back to the photo we will see what
00:01:22

It is transparent and what
00:01:24

is opaque, we go back in with alt in the mask, alt and click on the mask, and activate the levels with control L, we are going to make that
00:01:38

the sky is white and the stage is black so that
00:01:43

we can retain the real scene, but replace the sky
00:01:50

We have to
00:01:51

try that
00:01:52

This transition between heaven and what
00:01:55

we are going to keep it as abrupt and differential as possible
00:02:08

The closest thing here doesn't leave us much more, we don't have to
00:02:12

worry about the details down here, nor dissipate details of some cloud that
00:02:16

has been left
00:02:17

Which
00:02:17

We are interested in the transition between the building and the real horizon.
00:02:24

we will preserve and the sky
00:02:27

As you can see here are some areas where
00:02:30

We have not achieved the first one, but here yes, this is a very differentiated edge, and here for example it happens to us that
00:02:39

Of course the building has light colors and you can't differentiate them.
00:02:45

If we give asift inside the mask we deactivate it, then the color difference between this sky and this building is not the same as
00:02:55

between this sky and this building
00:02:58

We enter the mask and here when the shapes are straight with the selection of the deadline we can go to make the silhouette of our stage and the rest of the edge we go out of the canvas, we have to
00:03:41

fill in everything with black
00:03:43

There is inside the selection, we click here and we have black as secondary color and with control and delete we fill the selection with black
00:04:02

The sky, for example, has been left to us
00:04:04

the same, we change the secondary colors, but white, subtract and here we have it
00:04:13

a slightly blurred area, we deactivate and need to keep this transition
00:04:23

So we come here, we copy, we can also use the brush with a high hardness, we are painting white and we would already have our mask to act, we need that
00:05:02

or the other way around, we go to the control mask and invert and we would have our stage and below it the sky layer, as a final detail, if we see the transition a little with saw teeth,
00:05:28

We can enter the mask and apply a blur filter.
00:05:34

Gauciano with very little to do
00:05:38

blur the transition and it remains
00:05:43

as integrated as possible
00:05:50

So far a quick and effective way to replace one sky with another, I hope that
00:05:58

It has been useful to you and we will see you in the next one.
