- [Glyn] Hi, I'm Glyn Dewis, and in this video
I wanna show you how you can very quickly
and easily reduce or remove skin reddening
using a simple hue and saturation adjustment layer.
(camera shutter clicking)
Okay, so before we get on with reducing reddening in skin,
let's just go through some basics of using
a hue and saturation adjustment layer to change some colours.
Easy example we've got on the screen now.
You can see this guy wearing this rugby kit,
this blue and white rugby kit.
If all I wanted to do was change the colour of that kit,
I can choose a hue and saturation adjustment layer.
And in there, we've got this Masters menu.
If I click on that and choose Blues,
I can then simply use the Hue slider
to change the colour of the kit.
And that's generally doing that,
because the blue in the original kit
is pretty even across the whole of it.
So very, very simple, very quick, very easy.
Now, takin' it one step further,
if we look at this Lamborghini here,
this has originally been photographed outside,
cut out, and put into a new scene.
But one thing that we needed to change
was the windows here, where we can actually see
the light from outside still visible,
givin' us this blue in the windows.
Now, if I use the same technique as the rugby player,
so I choose a hue and saturation adjustment,
I change from Masters to Blues,
now when I use the Hue slider we can see
that not all the blues are being picked up
like they were when we used the rugby kit.
Now, at the bottom you can see
these two coloured bars, and there's four markers.
Two middle markers are basically sayin'
the colour above it is what you're selecting.
The two outer ones are kind of like featherin'
the colour off.
So it's basically saying although you wanna choose
the colour in between these two middle ones,
we'll also allow a little bit of this colour
on either side to come in as well.
So obviously the settings we've got at the moment
aren't enough, so let's just bring that back to 0.
What we can do with these markers, then,
rather than just having it default
as what Photoshop says we're gonna include,
we can grab one of the outside ones,
bang them all together, then click on this,
plus sampler, then click down and drag all over the window
to go all over the blue.
And you'll nice as I do that, those markers have now
separated and basically Photoshop is saying
wherever you clicked over, these are the colours
that are in the window.
So now I can actually click on the hue slider
and start to come in and change the colour of the window.
Let's just say that I wanted to maybe reduce
a saturation in that window completely.
Grab the saturation all the way to minus 100.
It's pretty much gone apart from this little bit.
So I could just click a little bit more over top of it.
But if that doesn't work, just come in, grab one of those
pointers and drag it over a little bit more
to say, just bring a little bit more of the colouring
outside there, bit more of that cyan,
and now you can see it's completely gone.
So we can use that now when we're looking to change
the redness or reduce the redness in somebody's skin.
Here's a perfect example that I've got.
This is a guy that I photographed
from the Bichester Home Guard,
they're a living history group.
And we can see this chap here's got a bit too much
reddening in the skin there on his cheeks,
certainly on his nose and maybe a little bit on his
forehead as well.
We can change that now completely, really easily,
using a hue and saturation adjustment layer.
So just like before then, I'm gonna click on the hue
and saturation, this time we've got Master,
I'm gonna change this to Reds, because that's the colour
generally we want to change in his skin
and again as before, Photoshop gives us these pointers
or these markers at the bottom to say
this is the colour range that we're now going to affect.
So what we can do here is just bring up the saturation
all the way to plus 100.
Obviously that's going to increase anything
that's red in the picture is going to get some kind of
saturation in it.
The skin has clearly got a little bit of red in it
so that's been saturated a bit more there,
it's gotten quite orange.
But the most saturated areas,
the most red areas in the picture,
were the areas that we wanted to change on the cheeks
and the nose.
And you can see when we look at it now,
they've gone pretty much nuclear on his face.
They're really starting to stand out.
So what we can do, now that we know we're affecting the reds
is tell Photoshop to really narrow down now to only
affect the reds in the picture that we want to change.
So with these markers, rather than me
grouping them all together
like I did with the Lambourghini windows,
I'm gonna click in the middle of them.
And I'm actually gonna drag it over to the lefthand side.
And as I bring it over to the left,
we can see now it's starting to narrow down the areas
that are really dominantly red in the picture,
and that was those areas that we wanted to change,
on his cheeks and on his nose.
And you can see, if we go all the way to the left,
no reds have been selected.
But if we bring it over to the right a little bit,
we can start to introduce the most saturated areas here,
the most red areas are definitely on the cheeks
and on the nose just there.
So I now know that the position of these markers
is just around the red area that is this area on the face
we want to change.
So let's just bring the saturation back to zero.
So all I'll need to do now then, if I want to reduce
the red in the picture is introduce the opposite
colour, which in the colour wheel, will be cyan.
So I'm gonna grab the hue slider, and drag it over
to the right-hand side.
And if you look at the picture now you can start to see
that that redness is definitely disappearing,
to the point that it's literally all gone now.
So here's the before.
And the after.
I'm to zoom in just a little bit for you as well.
So we go before, after, before, after.
Now it might be that there's areas that were affected
that you didn't want to be affected, like let's say,
his lips may be, there's a bit of red in there
that you didn't want to lose out.
Well because we've used a hue and saturation
adjustment layer, we have a layer mask attached to it.
So I could juts get a simple round soft brush
with a blank foreground colour
and paint over the lips to remove the affects
of that adjustment layer.
And that is that.
A really quick, simple way of reducing reddening
in skin.
