- [Instructor] Hi, I'm Glyn Dewis
and in this video, I've got a really
quick and easy technique for you to show
how you can match the colour of objects
in your pictures using Photoshop.
(camera shutter clicks)
Hi folks, just a couple of things in before
we get started, the first one is,
in the bottom right hand corner of your screen,
you're gonna see my logo, now if you
get your mouse and you click on that,
or if you're on a mobile device,
just press it with your finger.
It basically means that you follow
this channel, or you're kinda subscribing,
that's what YouTube call it.
It's completely free, but it basically
means that you won't miss out on any
of the free videos that I post on
a fairly regular basis and also kinda
lets me know that you're out there
and you're throwing back a little bit of support.
So that's the first thing, the second thing is
that the actual technique I'm gonna go through now,
a big shout out goes to Russell Brown,
who have sort of do this particular technique,
but I've kinda adapted to suit
my own particular way of working,
so that's what we're gonna go through now.
Looking at the picture on screen then,
what we've got here, this was from a client shoot
that I had earlier on this year, 2017,
where in the final brief, what they said was
that they needed the three seater sofa
to match the colour of the brown chair.
The first thing we need to do,
I need to isolate this sofa from everywhere else
in the picture, because it's only
the sofa I wanna change the colour of.
So, I've made a very, very quick selection of that,
I'm not gonna let you sit there and do that,
but let me just load it it, go to the select menu,
choose load selection, and I've got it saved in here
called, yellow sofa, click okay
and you can see the marching ants.
Now, what I'm gonna do is I'm gonna put
that selection up onto its own layer
and I can do that by holding down control key on PC,
command key on Mac and pressing the J key,
to jump it onto its own layer and if I turn off
the original picture there, there you can see now,
the selection of the actual sofa.
Now, when it comes to actually doing
the actual technique, what I could do
ordinarily, depending on which technique I was using,
I could literally make the adjustments now,
and just kind of eyeball it between the two,
the sofa and the chair, but that can be
a little bit challenging, so I wanna show you
one way of doing it, which is gonna
really, really help and make it a lot easier.
So, what we're gonna do is, I'm gonna zoom in
and what I'm gonna do is I'm gonna get my
marquee tool and I'm just gonna make
a very small selection on the arm of the yellow sofa.
Something around about there.
Then what I'm gonna do is I'm gonna hold down
the alt key and control key on PC,
that's the option and command key on Mac
and when I do that, you'll notice that now
that my cursor, has got two arrow heads,
one black and one white, and what this
allows me to do is now click and drag
a swatch of that yellow sofa and I can now
place it on top of the brown chair,
and as you press command or control D,
to get rid of those marching ants.
Now I'm gonna zoom in, and just get it around about there.
The idea here is now, that swatch is on the
same layer as the sofa, the big yellow sofa.
If I can now change the colour of this swatch,
so that it kinda blends in and almost disappears
on this brown chair, the colour of that swatch
is gonna go, is also gonna affect the sofa.
Now, we're gonna do it by using greyscale,
let me show you what I mean.
Now, as you can see, I'm currently working
on a colour image and the colour space I'm working in,
which is Adobe RGB, now if we go over
to the right hand side, let me click on the channels,
we can see how that RGB colour space is all made up.
The top here, we've got the RGB composite,
that's what you can actually see
on screen now, the full colour picture,
and underneath, the three individual channels.
Red, Green and Blue, but what you'll see is
that they are represented in a greyscale value,
so that's the red channel, the green channel
and the blue channel, and that's gonna
really help us out now, when we come to
actually make these changes on this particular picture.
Now, what I wanna do is just first of all,
click on the RGB composite and we'll
zoom back in now onto that swatch.
Now, first thing I wanna do, I wanna click on
the red channel, so I now need to make
the red channel values of the swatch match
the red channel values of the brown chair,
and I'm gonna do that by using curves.
I'm going to go to the image menu,
choose adjustments and curves.
Keyboard shortcut there, command or control N.
Now in here, we're already on the red channel
and I'm actually gonna click in the bottom left hand corner,
is a little icon here called the target adjustment.
Now, depending on what version of Photoshop you're using,
you might find that in a slightly different place
on that dialogue box, but basically what you're looking for,
is a hand with a finger sticking out
and an arrow above and below it.
That's your target adjustment.
I'm gonna click on that, bring my cursor
over into my image and I'm gonna place it
just above the swatch, click and then start to drag down.
Now as I do that, you'll notice that the actual
swatch starts to darken down and we can see now,
what I'm gonna do, I'm want to try and make it
blend into the arm of chair, so
I tend to find when I get to this point,
if I squint, it kinda helps me do
this little process a little better.
We'll take it to around about,
that's looking pretty good there,
so then I click okay, now I need to do
this process now on the other remaining channels,
the green and the blue.
So I click on the green channel,
you can see the swatch really stands out
on the green channel, but again,
we're gonna go to the image, adjustments
and curves, click on that target adjustment
for the cursor just above the middle
of the swatch, click down and then drag downwards.
Get it to around about this point here,
then I start to do some squinting action.
So we'll go from around about
there's looking good, click okay
and then finally, on the blue channel.
Again the swatch is really standing out,
so we go to image, adjustments and curves,
click on the target adjustment,
bring the cursor just above the swatch
in the middle, click down and drag downwards,
quite away, let's go for around about,
I'm gonna go for there and then click okay.
That's the red, green and blue
greyscale values have now matched
pretty much on the swatch to match
those of the chair, because it's
kind of blending in, we can see that now,
if I click on the RGB composite,
can you see how that swatch is pretty much disappeared?
So now then, what we're gonna do is,
click on the layers, go back to the layers,
let's now double click on the hand tool
to see how by changing that swatch colour,
has affected the sofa, because it's on the same layer.
Let's just double click on the hand tool
and we can see now that pretty much,
we've done a damn good job there,
of getting that three seater sofa,
to match in with the chair.
Now, of course, they're different material,
the chair is leather, so we've got that kind of shiny
kind of surface to it in those highlights.
But then a natural sofa, is kind of
like a tightly woven material.
But, actually there's one little thing I did
in the final image that was delivered to the client,
I'll show you that in a moment,
that I did to kind of help it to look
almost like the same kind of material as well,
so we can kind of fake that.
But, just going back to the actual sofa here,
if you thought you needed darkening down,
one thing you could do, maybe go back to the curves,
we're gonna add a clipping mask now,
so that what I do with these curves now,
only affects the layer directly below,
which is the actual sofa.
If I didn't do what is called a clipping mask,
it would make the whole picture go darker.
I just click the middle of the curve here,
just drag it down just a touch,
somewhere around there, so now we can see
before, after, before, after, that'll be fine.
So now let me show you then, as a little bonus,
in fact before we do that, we'll click on
the actual cutout of the sofa there,
zoom in, I wanna get rid of this swatch.
Let's get the eraser tool and we'll just
paint that swatch away, cool, that's gone.
Alright, the final thing, a little bonus thing for you,
just to show this one here.
What I'm gonna do now, I'm gonna create
what's called a merge or stamp layer
to the top of the layer stack.
Shift, control, alt and E on PC,
or shift, command, option and E on Mac,
and then what I'm gonna do is I'm gonna go to the
filter menu and choose filter gallery.
Now in here, lots and lots of different
kind of effects you can have.
In the artistics folder here, if I click that down,
there's about 12 or 15 different varieties.
But one of them is called, plastic wrap
and if I just drag this over, you can see
what it's actually doing to the picture here.
Now we can play around with these three sliders,
I've got on the right hand side.
Let's just bring up the smoother
just a little bit more, and in fact,
let's just take it down to touch actually, 13.
Yep, something like that, and we don't really
want much detail and we'll just click okay,
and you can see now, that it's done that
plastic wrap effect to the whole picture,
but I only want it on certain parts.
So, what I'm gonna do now, I'm gonna hide that effect
by holding down my alt on PC or option key on Mac,
clicking on the layer mask icon,
that adds a black layer mask and then
what I'm gonna do is, just zoom in,
I'll just show you a little bit
on this arm over here, let's just go to here.
I wanna get a brush, I wanna get a white brush,
100% opacity, I'm gonna bring the actual flow down
just a little bit and what I'm gonna do is just
making sure it's soft, nice soft brush.
There we go, and this is what I actually did
before I delivered it to the client.
So a few brush strokes now, going around with
that plastic wrap filter, just to apply
or reveal it rather, in areas that I want it to be,
just on little bits of the sofa.
We'll come down to here, a little bit more there,
paint on that bit, and what I did
before I delivered it to the client,
went round the whole of the sofa,
just adding this kind of fake,
leathery kind of look to the material.
But you can see, it doesn't do a bad job,
by kinda faking the look there.
Cool, there we go.
That's just a real quick extra little tip there for you.
So that's pretty much it, but just before I go,
quick reminder, make sure if you haven't already,
