Illustrator introduced Live Trace
a long time ago, and it's a really
powerful feature.
It just needs a little bit of help,
and the best place to get help
is Photoshop.
I'm going to show you how you can keep
Live Photoshop elements, Live Trace together
and update them; let's have a look.
Here we are in Illustrator CS5.
On the right hand side, this is an
image that I'm going to trace.
Up at the top if I click the Live Trace button,
this is the example we get
much like the one on the left, and
for some people this is fine, but
you'll notice lots of little problems down
in here, and we're losing definition in his eyes.
We're losing a lot of the clarity in the image.
On the left is the exact same image,
but it's been opened up in Photoshop,
and I'll show you what's going on there.
If we jump to Photoshop,
this is the image, and there it is
on the background.
There's lots of detail inside here that really is
completely useless to Illustrator so I'm going
to run a smart blur on this, and you do that
right in the filter menu, blur, smart blur,
and smart blur what it does is
it's smart enough to blur inside the edges
but not around the outside of
these high-contrast areas, so if I just turn
that off and turn that back on,
you can see I've got a layer now where
that's working a little bit better.
Next up, I notice that when I live trace this,
I was losing some definition in his nose area
and in the eyes so by just adding
an adjustment layer, and you can do that
simply by coming down here and
choosing the levels adjustment layer,
or you can go to the levels over here
on the adjustment panel, and what I've done
here is I've just created levels on the right
hand side that's brightening up these areas.
Remember it's not important what this
looks like in Photoshop; it's more important
how Live Trace is handling this, so when
I force the area above the eye to be lighter,
then it's going to trace it accordingly.
Again, below this eye, underneath the nose,
and the other adjustment layer I added
was a darkened layer so if I turn that off
and turn that back on, I'm just darkening
the area on the right hand side of the nose.
Just to let you know how these are created,
whenever you add an adjustment layer for
something like levels you get a mask
inside here, and if I hold down the Alt key
on windows, option on Mac, I'll see that mask.
Basically whatever is black is hidden,
what's white is showing, so whenever
I come into this area and paint with white,
I'm actually painting in that lighter area.
So you've got complete control with
a soft edge brush to introduce those colors.
Next up, if we just save this and go back
to Illustrator, Illustrator is going to warn us
that something's been updated.
Do we want to update this now?
Click okay, all of sudden you see on the
left hand side it's already looking better.
We can see a bit more definition around the eyes.
It's starting to pop out a little bit more under
the mouth now, but we've got more work to do.
I actually want this to be a grey scale image
with some more clarity; back to Photoshop.
Next up, posterize.
In this particular posterize setting has
a level of 2, and you can see that it
really starts to knock this out to
more of a solid color.
Next up, I just created a layer and
filled it in with white.
This is no different than any layer
that you would grab a paint brush and
start painting white out so as I paint
this out, it's going to be traced as
white instead of black,
and then we've got another level
inside here, and this one is really great.
So if I turn off that white layer,
what this level's layer is doing,
if we look over here on the right hand side,
you can see that I've just taken the
output value and lowered it,
which makes everything that was white
grey, and then when we paint white
it looks like we've got nothing in the background
so now we're getting closer to our grey scale
image with black accents and our white background.
So I'll save this,
jump back to Illustrator.
It's going to warn us, again, update?
Yes, okay, now we're getting close.
Next I want to add a grey scale look to it.
So in our presets we've got lots of
them inside here and you can create your own.
I'm going to go to grey scale, and
for the levels I'm just going to choose 4 levels
of grey scale, and then
double click inside here.
This takes me right back to my settings,
so this is the grey scale settings, and this is
the important one down here: ignore white.
We want the white that's in the background
to disappear instead of having to delete it
in Illustrator, I'll choose to ignore white,
click trace, and watch what happens
when I bring this to the front,
and I drag it over.
Wow, what a difference between
the old and the new.
This is such a great way to work.
Remember we're still connected to the Live Photoshop file on the other side
so if there's any tiny little area you don't like,
grab a paint brush and start painting, and as you notice,
it doesn't really matter what color it is.
I think we had some yellow in there,
and some black and some grey.
The final result here is a beautiful grey scale
traced gorgeously in Illustrator CS5.
Let's have fun with some Live Trace.
