Essential Tips
FLASH PHOTOGRAPHY There
are many types of lighting. In fact, the study of lighting in
photography is a subject itself. However, most beginning
photographers work with two types of light: available or existing light
and electronic flash, sometimes called strobe light.
Te
shutter speed on SLR cameras must be set on the camera's strobe
setting when using an electronic flash. The strobe setting
varies in the type of camera you have. If you were to set a
faster shutter speed than the strobe setting, the shutter would be
open part way when the exposure is made. This would only expose
a small section of the photograph.
Electronic
flash units are great for action shots and portrait lighting. The
flash of light is so fast (1/1000 sec or shorter) it freezes moving
subjects, providing the photograph with a clear unblurred image even
though the shutter speed is relatively low. A
few flash cautions. If the flash unit is close to the lens and the
subject is looking straight at the camera you may find the eyes to be
reddish in color photo (the so-called "Red-eye"). The
effect can be prevented by having your subject look slightly on one side
or by mounting the flash unit to the side away from the lens. A
bracket can be used for this purpose.
If your
subject wears eyeglasses, reflection with the flash can be a
problem. This can be prevented if you have your subject hold his
head slightly to one side. Flash
units can also produce reflection from shiny backgrounds like windows and
mirrors. You can avoid these reflections by shooting at an angle to
the window. It
is also a technique in using the flash units to bounce the light from the
ceiling or wall (best if you have an adjustable flash). This
diffuses the light that illuminates your subject and makes that light less
harsh and more natural.
