The image above is the image we will work with. Start krita with this 
image (in the documentation folder
<filename>$<envar>KDEDIR</envar>/share/doc/HTML/en/krita/tutorial-select-layer-sample.png</filename>) 
and save it to your Home folder (by choosing <guilabel>Save Image As...</guilabel>).

Then open it in &krita; &mdash; your screen will look a bit like this (we have
zoomed in):

Now try to select the outline of the head with the <guilabel>Select Outline</guilabel> tool: 
</para>

<para>
After you select it, it should look a bit like this picture:

If you accidently select too much, you can cut that part easily off by switching the tool to <guilabel>Subtract</guilabel> mode: 
</para>

Now it's time to make the edges of the selection a bit fuzzy. This can be done by applying <guilabel>Feather</guilabel> to the selection. 
</para>

<screenshot>
<screeninfo><guilabel>Feather</guilabel> selection</screeninfo>

<phrase><guilabel>Feather</guilabel> selection</phrase>
</textobject>
<caption><para><guilabel>Feather</guilabel> selection</para></caption>
</mediaobject>
</screenshot>

<para>
Now cut the selection, using
<menuchoice><guimenu>Edit</guimenu><guimenuitem>Cut</guimenuitem></menuchoice>.
Delete the current layer with
<menuchoice><guimenu>Layer</guimenu><guimenuitem>Remove
Layer</guimenuitem></menuchoice>. Paste your selection, with
<menuchoice><guimenu>Edit</guimenu><guimenuitem>Paste</guimenuitem></menuchoice>.
Now we give ourselves a bit more room to work in by resizing the image a bit.
Use the <menuchoice><guimenu>Image</guimenu><guimenuitem>Change Image
Size...</guimenuitem></menuchoice> dialog for this.
</para>

<para>
Add a new layer, and place it below the old layer. You do this by selecting
the new layer in the layerbox, and then pressing the little 'down' arrow at the bottom.
Now we are going to select the area around the head with a contiguous select
(the tool has a selection-with-bucketfill icon at the border).

<para>
Feather the selection again, and invert it.
Select the <guilabel>Contiguous Fill</guilabel> tool (this is a different tool than
the <guilabel>Contiguous Select</guilabel> tool) and use it on the layer. 
</para>

<para>
Deselect with <menuchoice><guimenu>Select</guimenu><guimenuitem>Deselect</guimenuitem></menuchoice>.
You'll notice some artefacts of the feathering at the sides. You can select them easily with a rectangular selection and then cut them.
