Open
nash
This technique involves firing the flash manually while the
camera shutter is open.
You can use it for a variety
of
creative ellects. For example.
while
the shutter is open the
fl
tm
records both the
imag~
lit
by
the existing light and
the image
lit by the flash. You can capture both a sharp
and a
blurred image in the same picture
10
create a feeling
of movement.
Or. in a large dark interior you can open the
shutter and fire
several electronic flashes from different
positions until you have
lit the entire scene.
Synchronizalion
speed
When taking pictures with your Vivitar electronic flash.
always try to use the fastest shutter speed that provides
full electronic flash synchronization (refer to your camera
instructions for this information). Tnis
will eliminate
"ghosts"
or
blurry images
of
brightly lit objects in the
background.
Group
shots
When photographing groups of people. bounce lighting
gives an even and pleasing coverage
of
the subject.
Arrange the
group
so that everyone is about the same
distance from the camera.
If you're not careful. people
closest to the camera
will be overexposed or " washed
out."
and those furthest away witt be underexposed because not
enough
light reached their spot in the picture. Be sure to
move well within
th
e lIash range indicated on the
Calculator Dial and remember to estimate the entire bounce
distance if you are using bounce flash.
Flash fill
Electronic Ilash can
be
used outdoors to ·fill·in· shadow
areas.
It softens hard shadows resulting from bright sunlight
and is particularly
useful wi
th
color
slide film. which can
record
only a limited contrast range.
