First of all, the example you seem to be shooting for is the only image
in black and white. I'm guessing that's because it's overexposed to the
point of being blown out, so the photographer decided to make it an
'art' piece. Dunno, though.
Second of all: To make the bad example image you talk about look more
like the first one, here's what you do:
Open the image in Photoshop. Apply a curve (I like an effects layer, but
you could just do a curve to the image if you prefer).
Now, you're staring at the Curves dialogue. Click on the little
two-arrow thing at the bottom of the grid so the white arrow is to the
left, and the black is to the right. (This is only so the rest of my
instruction will work.)
Plant an anchor point right in the middle of the curve. Just click on
the curve at it's midpoint. Now add another point to the left of the
point you just made thusly: Click on the curve to the left of the
midpoint and drag it down. The curve will flatten at the top and bottom,
where it bumps up against the edge of the grid.
And voila. You have completely ruined a nice image with good tone.
You can also find a good midpoint by sampling from the skin of the
subject. While you have the curves dialogue open, you can click on the
image and the color value of that point in the image will be displayed
as a circle on the curve. So drag the pointer around on the face, say,
especially over an area of high contrast (like a shadow under the nose,
perhaps, or the smile lines between the nose and the corners of the
mouth). You want to keep these details, so you put the midpoint there,
and then destroy the rest of it by slamming the curve into the edge of
the grid. Or, of course, applying a more subtle curve, even adding more
points for more control.
This works especially well in Lab mode with color images, where you can
change the contrast without changing the hue.
HTH.
