Watercolour Wash Effect using Channel Mixer

Hello and welcome to InAffinity. Just for
a bit of fun let’s do a picture of watercolor but we’re going to do it using
the Channel Mixer tool. So, let’s start off. We’ll go to our background. We’ll hit
Ctrl-J twice to duplicate the background twice. We’re going to need that. We’re going to
turn off the top two layers then, with the bottom layer, what are we going to add
but the Channel Mixer! So what we want to do with this, is we want to get just the
colors. So, to get the colors we just go to CMYK then go to the blacks and say
where there is blacks we want no blacks. So turn that right down and we get
colors. I’m going to put the blacks back in another layer, so that’s kind of nice.
What we’re going to do with this now is going to make it a watercolor. We’re
just going to blur it. So we’ll put on a blur. Here’s a Gaussian blur and we’ll
turn up the radius pretty high, so it goes a bit washy. We can always come back and
change this if it’s not what we want. We can just wonk it up now.
Wherever. Something like that. We’re going to select this layer
and we’re going to take the Opacity down a bit so it’s a little bit
washier. We’re going to effectively put a paper or a wash
underneath. You could put a paper texture underneath this but let’s
just put a fill layer. So we go Layer, New Fill Layer. And I’m going to put that
underneath. We can leave it white, so this is white here, or we can put a
light color underneath it. Let’s say something like that. Kind of
matches a bit. Just off-white slightly or anything looking like that, kind of matches
a bit. It’s not looking much like a picture at the moment, so let’s put the next layer on.
Now then, what do we need to do this? What we need now is some blacks and whites
so we’ll put another layer on here of the Channel Mixer. This time we’re going to
go to a different model to RGB here. We’re going to go to Gray
because this is for a black and white layer. And then we’re going to the Alpha settings, which is transparency, and turn
this right down. See, what we’ve got here now is already looking pretty
much like a washed layer, because if I turn this one off the bottom layer you
can see here … turn that off altogether … you can see what we’ve got here. By
turning the Intensity down in the Alpha channel for grays, we’ve just got grays
left here so all the color has gone. So, we’ve got the color on the
first background layer here and the monochrome on the next one. You can
leave it like that if you like or you can play around with a little bit more
with the top layer. Take this layer and we’ll bring it down a bit here so
you can have … you know, if you turn it down a bit, around the 50% ish
mark it looks more like a pencil when you’ve got the black and white. 50% is
good for pencils but we’ll put on a little bit more of control on the top
one here and another Channel Mixer. And just to mix it up as we’re doing this go
down to the LAB settings and then we’ll go to the Alpha controls again. I’m going
to take the Lightness and turn this right down. There we go. That leaves
us just a little bit more on top of that, so you can have this or this. And again
we can change the opacity to modify the effect. But I think I’ll leave it like
that. Okay, there we go. That’s our nice washy thing. Look at the
way the Reds are just sort of bleeding out of this and it’s sort of a bit smudgy. Much
nicer than the original, I think. Anyway, thank you very much for watching.
