Touching Up/Cloning Photos
Programs Used: Photoshop 6
Skill Level: Intermediate
This tutorial does not really have set a step-by-step procedure,
but is more of an overview of what you should be looking out for.
It requires initiative more than technique.
The first part of this tutorial will describe the usage of the
clone stamp tool on cleaning areas of a picture, and the second
part will describe a technique to attach an area of a body that
has been cut from the picture.
PART A: Touching Up
Copy the following picture into Photoshop:

We wish to remove the tattoo on her ankle so that it is just an
even skin tone like the rest of her leg. First select the clone
stamp tool (or press S) .
Now zoom into the tattoo to 500% and select a suitable brush. I
have selected a soft brush of size 13. A soft-edge brush is used
as the skin has to look blended and smooth. A hard-edge brush will
be used later for more precise cloning when we recreate a part of
her body. - 
To begin cloning, Alt-click an area of skin near the tattoo, and
to apply, click normally over the tattoo. Use this technique to
go back and forth between the source (clear skin) and the destination
(tattoo).
As the direction of the leg is vertical, it is best to clone the
part of skin right above the tattoo, and not to the left or right
of it as to retain the same brightness.

Keep on the same vertical path of the leg and keep to the skin that
is closest to the tattoo, as to keep a similar tone. If need be,
zoom in more and apply a smaller sized brush to the little parts
left over. This is a trial-and-error process and you may find yourself
going backwards in history, to use a better source. Here is my final
zoomed in cloned section:
Here is my final product zoomed out:

PART B: Recreating a Body Part
This next section makes use of the above technique but mainly makes
use of a good eye. I will not be using an example as the degree
of variance in which you can apply this technique varies immensely.
The variables include:
1. If you have many different pictures of the same person to source
from,
2. Size of the area,
3. Complexity of the area (eg. an elbow will be harder to recreate
than the length of an arm),
4. Amount of detail in the area,
5. Color of the source clone.
Here are some tips for each variable:
1. This variable makes the cloning easier. Using a hard-edge brush,
you can re-add the side of a leg, or corner of an elbow from another
source picture. You may have to rotate it, or alter its color balance
and brightness/contrast. Once added, the line that joins the two
areas should be cleaned up using the above touching up technique.
2. The larger the area, the harder it is to recreate, obviously,
as there is more of an area to make up. The best way is to just
recreate it a bit at a time, slowly rebuilding the area.
3. A good amount of source images (1) and the size of the area (2)
affect the easiness of this.
4. Using a smaller brush and zooming in more will help you work
a more detailed area. Once again, point 1 and point 2 will help.
5. A similar color is easier to fit in. However, if the newly cloned
area is noticeably off color, then cloning it on a new layer above
the picture is advisable. Then you are able to control its color
balance and brightness/contrast accordingly. When a similar color
is obtained, merge down the layer, then use a soft-edge brush to
the area.
There are many situations when you will need to recreate a part
of a person. Say there is a branch from a nearby tree covering part
of an arm, or the actual photo has been cropped so that part of
an elbow has been cut off, or part of the top of their head. It
may not even be a person! It could be anything else.
Use your intiative and keep out a good eye for similar areas that
you can use to clone and stamp. Good luck!
