exposure / noun.The act, or an instance, of exposing a sensitized photographic material, or the product of the light intensity multiplied by the duration of such an exposure.
Exposure is the heartbeat of photography. Put simply,
it is the process of light striking a photosensitive
material, such as lm, photographic paper or a digital
cameras image sensor. Understanding and being
able to control exposure is critical to successful
photography. However, it is a subject that, at times,
can appear complex and confusing not only to
beginners, but enthusiasts as well. So many things
can in uence exposure, including the time of day,
focal length of the lens, subject movement, light
source and any lters attached. Certainly, when I rst
began taking photography seriously as a teenager,
I found the theory and technicalities of exposure
tricky to understand. However, I quickly realized that
if you try to overlook this key fundamental, your
photography will suffer and never realize its full,
Exposure is a combination of the length of
time and the level of illumination received by
a light-sensitive material. This is determined by
three settings: shutter speed, lens aperture and ISO
equivalency rating. The shutter speed is the duration
of time that the cameras shutter remains open,
allowing light to enter and expose the sensor. The
aperture or f-stop is the size of the adjustable
lens diaphragm, which dictates the amount of light
entering the camera. The ISO speed indicates the
sensors sensitivity to light. At lower sensitivities,
the sensor requires a longer exposure to get a good
result, while at high sensitivities, less light is needed.
If the combination of shutter time, aperture
and ISO sensitivity is incorrect, the picture will be
wrongly exposed. Too much light falling on the
sensor will result in an overexposed image with
washed out highlights; too little light and the
image will be underexposed, appearing too dark.
Simply speaking, a good photograph relies on the
photographer employing just the right combination
of settings to form the correct level of exposure.
However, while this might be logical in theory,
I often ask myself: Is there really such a thing as
the correct exposure? While you could say that
a correctly exposed image is one that records
the scene or subject exactly as our eyes see it,
photography is a subjective and creative art. There
is no rule stating that a photographer must always
capture images that are authentic it is subject
to individual interpretation. Therefore, arguably,
a correct exposure is simply one that is faithful
to the vision of the photographer at the moment
he or she triggers the shutter.
Todays breed of digital cameras boasts highly
sophisticated and accurate internal metering
systems, which are rarely fooled even in awkward
lighting conditions. They have simpli ed many
of the technical aspects of exposure, for which
we should be grateful. However, a camera is still
only a machine; it cannot predict the effect and
look the photographer is striving to achieve. It is
for this reason that you shouldnt always rely on
your cameras automated settings. Remember:
you are the artist and, as such, you need to grasp
control from your camera. Fail to do so, and your
images will never truly convey your own individual
interpretation of the subject you are shooting.
XDamsel yEvery time you take a photo, you are recording
a unique moment that can never be repeated.
A good understanding of exposure is vital to
ensure your image is compelling to others and
faithfully captures the light, essence and mood
of that particular moment.

Digital Exposure Handbook
Basically, without a good understanding of exposure,
your images will never progress beyond the realm
of pleasing snapshots.
Exposure can be manipulated for creative effect
in so many different ways. For example, it can be
used to create the impression of movement, or to
freeze fast action that otherwise would be too quick
for the human eye to register. However, the skill isnt
just to know how to create such effects; you also
need to be able to judge when to employ certain
settings. This handbook will help you make the right
choices. It is designed to be an exhaustive manual
on the subject, covering every aspect of exposure as
well as offering helpful and practical advice on ways
to improve your photography in general.
My hope is that this guide will inspire you,
helping to open your eyes to the skills and techniques
required to manage and control exposure in order to
create images that succeed in relaying your artistic
vision. However, reading this book alone will not
improve your photography; you have to adopt and
implement the things you learn in your own picture
taking. After all, photography is a skill and, if you wish
to improve, it has to be practised.
X Church silhouetteIn many ways, there is no such thing as a correct
exposure. For example, technically speaking,
a silhouette is the result of poor exposure the
subject being grossly underexposed. However, no
one could deny that silhouettes create dramatic
and striking imagery.
