and more. The intensity of light is often controllable too, either through
power adjustment, in the case of artificial light, or through reduction and dif-
fusion when it comes to natural light.
Intensity.With artificial light, such as studio strobes or on-camera flash, a
photographer normally controls intensity by adjusting the power output via a
potentiometer. (This is usually a knob, switch, or button that reduces or in-
creases the light output, within the actual limits and capacity of the originating
source.) This will allow you to reduce the light intensity in quarters, thirds,
halves or, in the case of the more accurate and expensive models, tenths of an
f-stop.When shooting on location, I’m
always looking for light, light that
adds impact to the image, as in this
photo of Playboy Playmate Holley
Dorrough. When working in the vast
Moab desert, it’s often a drive to get
from location to location, so you
pack lunch, plenty of water and ice,
along with good ol’ toilet paper; the
days are long and dusty and it does-
n’t make any sense to drive over an
hour each way to your hotel. During
the middle of the day, when the light
is at its harshest, you look for loca-
tions that provide shade or relief
from the strong sun. In this case, we
found an old mine building. When I
find locations like this, I look at how
the light enters the building. Here, I
capitalized on the light streaking in
between the boards, along with plac-
ing Holley in front of the window for
an “overlit background” effect. In
Adobe Lightroom, I gave the image a
warm tone. (CAMERA:Canon EOS 5D
