using the layer mask. So now we can see

that we've selected most of the city

here. Now there's some pieces you'll

notice that aren't selected properly and

that's okay because down here on the

bottom we have this create mask from

selection. Before that you'll want to

click on select inverse to select the

sky. And now it's created that layer

mask. So, it's taken out that old sky

and it has put in the one underneath

that layer. Now, once again, you'll

notice that it's a little bit rough in

some areas and we still have some of the

other sky underneath. Um, but

thankfully, we can fix that. So, now

you'll notice that next to our city,

we've got this black and white image

here. So, this is the layer mask that

we've just created. And what this mask

does is it's basically a map showing you

which pieces of the image should be

transparent and which ones should be

opaque. So the white areas are opaque

and the black ones are transparent. And

when we have this selected, we can

actually paint directly onto it using

the paintbrush tool right here. Um, and

then we've got black and white. So those

are our colors. You can swap between

them. So, what we're going to do is is

we're going to paint in all of those

detailed areas that we're missing. Okay.

So, let's fast forward here. And you can

always adjust the hardness to bring back

um a little bit less of something.

You almost want to you just want to keep

going back and forth between

the black and the white. Okay. So once

again, the black color will remove the

gray sky. And then if I switch it to

white, it'll paint in um we want to

paint in the buildings with the white.

It doesn't have to be perfect um because

we're going to look at a few other

techniques

to make this look even better.
