Shadows and Highlights: The Mark of
Excellence

Back in the days of Black and White I worked in a
darkroom as a lab assistant; and sometimes students
would make the mistake of asking me what I thought.
If they wanted to learn this was not a mistake, but
if they just wanted me say how great their work was
. . . that was when it became a mistake.
Sometimes I
would advise them to crop tighter or change their
center of balance, but by far the most common
problem they had was with Shadows and Highlights.
I would ask a student to show me a pure "white" in
their print and they would point to a cloud or
something similar. I would say that's not white, and
they would argue with me. Now admittedly this was
done under safelights; but once I asked them to fold
over the edge of the print so they could see the
back of the photo paper, that's when I would say
"Now that's a pure white."
They didn't argue because they actually did have a
pure white, they argued because that's how they
remembered the scene in their mind. I had to remind
students again and again that unless you do
something different, the camera only exposes at 18%
gray. Likewise, in a darkroom, unless you do
something different the prints that come out are
also 18% gray. When you expose something at only 18%
gray, you are using a middle of the road type
exposure. That should be your starting point, not
your final destination.
In the Zone System developed by Ansel Adams there
are 10 zones or shades from pure white to pure
black. If you take a close look at most exposure
compensation settings; regardless if your camera is
digital or 35mm, most of them only give you a plus
or minus range of two f-stops. If the original
setting that your camera uses (18% gray) is zone 5
and you can only expose at plus or minus two stops,
that only gives you a visual range of five f-stops.
What happened to the other five zones?
Camera manufactures keep coming out with bigger and
better units every day, but to date, none of them
have developed a sensor as sensitive as the human
eye. You may remember those awesome white puffy
clouds, but that is because your eye sees and
comprehends a wider range of colors than just the
standard 18% gray. Remember, if you want a subject
to actually be white (a wedding dress for example)
you will have to give the shot more light than the
camera suggest. If you want it to actually be black,
(a black cat for example) you have to give the shot
less light than what the camera is indicating.
When it comes to light, it seems that many
photographers become totally obsessed by the idea of
controlling it. I mean we buy studio lights so we
can get more of it. We get reflectors and bounce
things off the wall. Why? All for the mistaken idea
that we need to get rid of the shadows. Let's just
take a moment, breath deep, and remember the
classics.
When someone says they are going to use Rembrandt
Lighting or Butterfly Lighting what are they
referring to? They are talking about studio lighting
setups that allow you to control the shadows, NOT
eliminate them. Shadows help to set the mood of a
shot. When you think about it, all lighting patterns
are defined by the shadows - not the light. If there
were no shadows, there would be no patterns. All
lighting would be the same.
Highlights are usually defined as the brightest area
in a photo. As my students learned, what you shoot
as white does not always come out as white. This is
often more obvious in black and white photography
than with color, but when you lack highlights you
also lack dynamics. When you shoot a snowy mountain
top and nothing is truly white, you have what most
of us to refer to as a "flat image". We call it
flat, because like a tire on your car if it's flat,
it just doesn't take you anywhere.
Fashion photographers often go to great lengths to
play with the highlights in the eyes, or in the
hair, or in a smile. A photo tip worth remembering
is that sometimes in an effort to get better
highlights, we over expose the image and actually
loose detail. That's referred to as burn out, and it
is not the same as a well thought out highlight.
With that in mind, I would like to redefine
highlights as: the brightest area in a photo in
which one can still see detail. The same is true of
a great shadow. A shadow is defined as the darkest
area of a photo in which you can still see detail.
If you see a picture of a cave opening and all is
black, you don't really have any shadows (you have
darkness.) If you can see eyes and a hairy outline
of some type of creature breathing the cool night
air, you can honestly say you caught something
lurking in the shadows.
The reason the masters went to such great efforts to
include shadows and highlights in their photos is
that it took their work to the next level. If all
cameras shoot at 18% gray; which is a middle of the
road type exposure, it is fair to assume that 90% of
the people in the world today are getting middle of
the road type photos (as far as exposure is
concerned.)
Many advanced amateurs (say 5 - 8%) do use exposure
compensation; but they are still on the high or low
end of middle gray. To ensure your images have the
same richness as the masters; like Ansel Adams or
Edward Weston, you too have to include shadows and
highlights. Look again at the images that impress
you, regardless of the subject matter . . . what do
they have that you do not? I am willing to bet that
it's in the details, and those kinds of details are
often found in the shadows and highlights.
