Hello all.
Today I'm doing a tutorial on how to easily draw a vector art.
It isn't a difficult process at all. All you need is a P.c and a little knowledge of the pen tool in photoshop

so Here we go:

Software used : PHOTOSHOP CS5.
You can get this programme at a software store near you

Steps:

• First; you pick a subject.
  my subject here is pretty, so please don't get carried away.

Get your photoshop running, then hit (CTRL + O), navigate to the folder where you have placed your subject.

Double click on the image to start.

With your subject in position

• Create a new layer and rename it as "OUTLINE"

• Hit (P) on your keyboard to use the pen-tool. (I suppose you already know how to use the pen tool).

• Create an outline of your subject by creating paths with the pen tool.
  Right click and then select stroke path.

You should have something similar to this

And this, when you turn off the subject image layer.

.

Please note that, I used Face-outline and Face-layer, read carefully, so you don't get confused.

• Create a new layer and rename it as FACE or SKIN, depending on the size of your subject. Locate your Wand tool and select it as shown in the picture below.
  Now on the layers panel, select the outline layer. Place the wand tool on the Face or skin outline and click.

The Face Outline shoud be selected.
Now select your Face layer,
Locate your paint bucket, choose your prefered colour and splash within the selected area.

Create different layers for lips, hair ,clothe and whatever you'll need to paint and repeat the step above to paint.

Your subject should be fully coloured now and looking all like a toon but without details. To add these details

*Duplicate your subject layer, by dragging the subject layer down to the "Create new layer" icon.
You should have two subject images. One label copy
Now move the copy to the top of the list of layers.

• Select the Subject-copy layer, that you have placed on the top of the list. Locate the Option "IMAGE" as show below. navigate through to convert the image to black and white.

• Locate the option "FILTER" → "FILTER GALLERY'

• Fom the options listed choose 'CUT-OUT'
  Set the values as shown below.

Click OK!

• Now do this, Where you find Normal on the layers list, click and select "multiply"

Now your SUBJECT-COPY should be looking rough from apply the call out effect.
You would notice 3 colours.
To fix this, hit 'I' on your keyboard to pick each of the colours, then hit B to use the brush tool and bush the edge where necessary to smoothen it.

As you can see, it is smooth and neat.
Note: Before doing this, change the option from 'Multiply' to "Normal" . And from "Normal" to "multiply" After that.
The Option "Soft Light" may also be used and Opacity reduced to somewhere between 70-60.

All done.!!!!!

And now to remove the unwanted areas from your Subject-copy image, In may case, its the back seat.
Even after reducing the opacity, some bits of it remain visible and would like show up over a light background colour.

• Select the Outline layer, use your Wand tool, place it on the unwanted area and click. If it would require two or more clicks, Hold Shift and click again.

• Select the Subject-copy layer and hit the layer mask icon as shown below

Now hit CTRL + I.

All done!!!
The unwanted areas should be deleted now.
Congrats!!

Adding a background

• create a new layer at the bottom of the lost.
  click on the semi circles Icon, below the lists and choose solid colour.

• Now choose , prefered colour and click OK.

All done!

You may add a bit of contrast.

Now save your work!!!
You can do this by locating "File" on the top left corner, Click and choose 'Save as' and choose preferable extension.

The end
