Photoshop Vector Tutorial
By: Brian Fitzpatrick
In this tutorial I will try and teach you the basics
of vector art in adobe photoshop. We are going to turn
this image into this
using photoshops pen tool. Before we get started dont
worry if you cant pick up on how to use the pen tool
straight away,
it takes a few minutes to get the hang of it. When
choosing a picture you want to vectorize make sure its
interesting,
has nice enough lighting and plenty of different
colours. The picture i'm using isn't the most
professional or epic photo but
its decent enough to make a nice vectorized version.
Step one
Open photoshop and open the picture of your choice. Do
anything you can to enhance the pic to make things
easier. I
usually like to double the image size so that the
final image will be twice the resoloution as the
original but you dont have
to do this.
Step Two
Select the pen tool and make sure its on the paths
mode and set to "add to path area". Now lets create
the basic shapes
and colours of the image. Create a new layer and zoom
in on the area youre working on(in my case the skin
areas) and
choose a point where you're going to start. Just click
on that area to mark the start of your path and then
move to the next
area of the object where it curves and click and hold
on that point. You will see that you can curve the
line while holding
the mouse button but this will also effect the shape
of the line in between the current point and the next
one. Usually this
isnt too much of a problem but if it is you can always
hold Alt while altering the curve to just adjust the
outer curve only. If
this all sounds gibberish to you then hopefully this
video(
pentool.mov ) will help
explain how to use the pen tool. After you get the
whole
way around your object click on the first point to
join the end and start points to form one continuous
line.
Step Three
If your object is divided around the picture(like how
my skin layer is two arms and the head) then once you
finish one line
go and start the other one by doing the same thing in
step two. Once you have all of the object selected,
choose the main
colour of the object and then select the path
selection tool. Now right click and choose fill path
and make sure its set to
the same options as shown in the image. Click ok and
your path should be filled with that colour. Now you
can delete the
path by right clicking and choosing delete path.
Step Four
Now move onto the next object of your choice and
repeat steps two to three(make sure you remember to
create a new layer).
Do this for the rest of your image except dont worry
if you have a complicated background, you can simplify
it or just replace
it with a single background colour later on.
Step Five
Now its time for the shading. You can do this by eye
or you can simply add a posterize effect to the layers
to use as a
guideline for the shades. To do it this way just right
click on the background layer and make a duplicate
layer and place
it on top of the layer you wish to shade. Now hold Alt
and click in between the duplicate layer and the layer
you want to shade.
This creates a mask for the duplicate layer as you can
see. Now desaturate the duplicate and add the
posterize effect found
in image>adjustments( I chose 2 levels to keep it
simple). Click on the layer you want to shade and add
a new layer. Using a
darker version of the original layer colour make a
path around the darkest area of the posterized image
and fill them like in
step three. After you fill your path you are going to
need to hide or delete the duplicate layer to see the
new shading. If you
chose more than two levels for the posterize effect
just simply make another layer with a darker or
lighter colour than the last
layer.
Step Six
Do the same to all layers(or at least the ones you
feel need to be shaded) and you should hopefully end
up with a nice looking
digital image like I did. Remember that these are just
the basics and you can make so much more with added
time and effort.
If you have any problems with the tutorial post it in
the forums and I or someone else should be able to help.
