the example you point to is not from specifically increasing contrast, its
just one light on the side, typically a bit too specular and without a fill
light to make up for it, nor a background light so that does dark/black.
This image shows a bright face cause they tried to retain some detail in the
shadow side, if they printed down for detail in the highlights the rest of
image would go stark black.

to get this effect you don't need to do too much, just use an off camera
light source.  You shouldn't need to screw up the exposure with editing,
this is a straight forward shot.

of course you do need some light, you could probably get a rapid fall off
with a window, pose the subject close to the far edge of the window, you
will get a bit of wrap around but a very rapid fall off, contrast.

one problem you may have is if you use any auto exposure functions, they
don't know what you are trying to do, they assume a medium gray period.
seeing a lot of white surrounded by black will confuse them, usually causing
over exposure in the subject as it tries to average in all the dark.

another thing to try is a bare bulb, as in take the lampshade off and move
it fairly close

a tripod is necessary.

Why would you think that?
