Exposure Compensation
By: Jakob Jelling
The
digital camera is in reality a great possession with
many facets of its utilities and not only that
knowing these utilities makes the understanding the
digital camera complete. The utilities are also so
very diverse that they too offer further
introspection of details in their varying
applications. Such an area is digital camera
exposure compensation. Only knowledge of digital
camera exposure is not enough, so the digital camera
exposure compensation requires some amount of
exposure in itself! This discussion is focused
towards that cause itself.
Looking at different digital
cameras, even temperately costing digital cameras
have arrangements for exposure compensation
settings. To explain in a bit detail, the exposure
compensation allows the users to control the amount
of light entering the lens. And thereby the
illumination of the photograph is decided. Exposure
compensation can be altered manually or by the help
of a digital camera's exposure compensation setting
that lets one override the metered exposure set
inside the digital camera itself. Strictly speaking,
the exposure values provide an expedient line of
attack to put a figure on the available light
intensity and therefore exposure.
As
per general norms of the users of digital cameras,
certain standards exist for selecting such values.
These values are specifically known as Exposure
Values (EV). Selecting an up to standard Exposure
Values (EV) helps maintain the details contained in
dark areas of a photo, or diminish the more than
usually bright areas. Again, looking from technical
point of view, the Exposure Values are numbers that
refer to an assortment of combinations of apertures
of lenses and shutter speed respectively. They have
a selective range of values, ranging between -2 to
+2 Exposure Values (EV). As a general rule positive
exposure settings are used for cases where bulky
areas of a scene are especially bright such as
taking pictures of a snow scene and also during
times of photographing when the background is a good
deal brighter than the focal area under
consideration. Also, negative exposure settings are
used for cases where bulky areas of a scene are
especially dark and also during times of
photographing when the background is a good deal
darker than the fore area under consideration.
One point that is worth noting
is that light meters cannot see color. They deliver
every scene as 18% middle gray and become accustomed
to the exposure accordingly. And most digital
cameras will allows a photographer to compensate the
exposure by 1 to 2 EV plus or minus in 1/3 or 1/2
stop increments. A very important realization for
any photographer is that the right exposure is only
"correct" in the eye of the photographer; Exposure
Value compensation can also be used as a creative
tool.
With this information available
to the users of the digital camera, the knowledge of
digital camera exposure as well as digital camera
exposure compensation becomes. But it is only
knowledge, the proper acquiring of the whole feel
comes only from personal experience.
