Layer > New Adjustment Lay-
er > Brightness/Contrast
is
your first choice on the list of
Adjustment Layers
.
Like many of the other adjust-
ment layers, this option consists
of sliders that can be used to
change the characteristics of an
image.
This particular option allows
you to change the
Brightness
and
Contrast
in an image. In-
creasing
Contrast
will generally
add impact to an image. The ad-
vantage of using sliders is that
you can instantly see the effect
of these adjustments.
Bright-
ness
is a little less obvious. It is
not the same as changing the
Ex-
posure
of an image. It is more
like turning up an interior light.
If we have a landscape scene
that includes storm clouds,
Brightness
and
Contrast
can be
used to darken and add drama to
the clouds while maintaining the
brightness of the scene.
Exposure
darkens or lightens
the entire scene.
The next image shows the before
and after effects of this adjust-
ment layer. Notice how the rock
formation stands out in the enhanced image as compared to the original image.
