With ASA 100 film, set your lens to 14 ,

If the lotal bounce distance does not appear on the
Calculator Dial, first measure the distance from the fl ash to
the reflecting surface to the subject. Then,

Helpful Hints
Oil-Camera Direct Ughting
Shooling With the flash oU-camera helps eliminate harsh
shadows,
washed-out foregrounds, and "red-ey e ." When
using
direct lighting, try holding the flash above and slighlly
to the right or left of your subjecl lo produce betler
modeling, You can di ff use dilectlig ht to achieve a sol ter
tone
by placing a handkerchiel over Ihe flash head, making
sure Ihe
Sensor is lefl uncovered.
Bounc e LIghting
Solt lighting with a minimum of harsh shadows is achieved
by bouncing Ihe light 011 a reflective surface onto your
subject. Light colored walls. ceilings, large sheets of paper,
or even bed sheets make ideal
re fl ectors. This type 01
lighting is similar to soft, hazy sunlight or window light.
When using color film, be carelul about the color 01 the
reflective surface, as the
bounced light will take on the color
01 the reflector. Unless you are trying for special effects,
irs a good idea to use a gray or lighl-colored surface.
As a general
rule when using bounce fl ash, set the flash
head
lilt on the 283 so that Ihe tight is di r ec ted atlhe
'"
uSing. Note the resulting number ( rounded off to the nearest
f-stop), and open your lens 1 f-stop wider.
EXA M PLE : Using ASA 25 film at a total flash-t o- r eilector-to-
subject distance 01 20 lee! . , , Guide N o. 60 +- 20 = 3
(approx. f2.8),
Open your lens to 12 .
NOTE: When figuring flash-to-subjeci distance using
manual bounce flash, be sure 10 consider Ihe light
absorbtion 01 the rellective surface. Bouncing off surfaces
such as curtains,
lor example, will add to Ihe effective
distance between the
flash, the reflecto r, and the subject.
To insure properly exposed pictures when bouncing off light
a bsy~~ing surfaces, open your lens 1 additional f-stop
ove~e selting determined by any of the above methods.
Cameras with Builtwln Automatic
Flash Control
Some cameras have a feature which automatically sets the
correct lens apertures
for flash as you locus. For the camera
and
your Vivl ta r 28310 operate properly together, you must:
1
Se t the correctllash guide number for the film you are using
on the Guide Number Scale 01 your camera (reler to your
camera instructions lo r the location of the Guide Number
ContrOl): and
2
Make sure the Mode Selector ® is
set to
manual " M "; and

M ounlthe flash on Ihe camera and
tilt the lIash head to o ~ (direct
flash). The
proper flash gu ide
numbers

mid poinl on the ceiling between the flash and the subject.
Usi
ng th e S ullic ie nt Light Indi cator
If the green Sufhcient Light Indicator does not glow upon
firing a lesll1ash,
you will have to make adjustments that
allow more light to reach the subjec t. Sevoral alternatives
are listed below which may be used alone or in comb inati on
with one another.
1
Se t the Mode Selector to an automatic mode that utilizes a
2\ '-SlOP opening, and set your camera lens acco rdingly.
Shorten the dis t ance Ihe light must travel to reach the
subjec
t. This may be accomptished by moving the flash, Ihe
subject, the reflector (if using bounce flash) or by a
combination 01 the three.
3
Bounce the light oil a more reflectiVe surface (e.g, a white
wall rather than a white curtain),
NOTE: The indicator does not function in the manual mode.
MirrOf$
Never shoot Ilash pic tu res straight into mirrors, glass or
other
highly reflective surlaces, as th e resulting light
reflections may
ru in y our pictures. Stand al an angle so that
any reflections
will be directed away Irom the camera.
Hint:
If you can 'l see yourself in the mirror, you're safe.
Simula tin g sunlight
There are times when the sun disappears, but the pic ture
calls lor sunlight. Your electronic flash can then be used
as the malfllight and very successfully simulate sunlight.
When you wish to simulate sunlight outdoors in dull
weather, first determine the proper exposure lor the natural
daylight and then StOp down one lull I-stop . Determine the
correspond ing lIash- t o-subjec t distance for that I-st op .
Set
you r fla sh at that distance. The flash will th en serve as
