Somewhere in the .POV file (probably at the end) you have something like:
light_source {
<-60,-285,-186>
color rgb <1,1,1>
}
The first triplet <-60, -285, -186> is the position of the light. Try changing
the coordinates (and signs) one at a time, to see the effect.
The second line gives the intensity/color of the light. You can add a factor
to this, and you can change the color:
color rgb 1.5*<1,1,1> // more white light
color rgb 0.5*<1,0,0> // dim red light
etc.
You can have as many lights as you want in the scene. Just remember, each
light adds to the total rendering time.
If you have produced the .POV file with L3P, there will be three light
definitions at the end of the file. You can test with an additional light,
removing a light etc.
You can also use a light which doesn't cast any shadows to show more detail of
the surfaces without cluttering up the image. You'll probably use a dimmer
light for this.
light_source {
<-60,-285,-186>
color rgb 0.5*<1,1,1>
shadowless
}

In the same way, somewhere at the end of the .POV file, there is something
like:
camera {
location <300,0,10>
sky -y
right -4/3*x
look_at <-41,-84,6>
angle 45
}
By changing 'location', you can look from any position, by changing 'look_at'
you decide what should be in the center of the picture.
If you want to lessen the perspective distortion, move the camera away a lot,
and make the 'angle' smaller (it's just like a telephoto lens).
Happy rendering
