2. Once you have set the white balance and flash mode on your
digital camera you may mount your camera onto the flash
bracket.
3. Turn on your digital camera and take a few shots using the
camera's built-in flash. If you can, count the number of flash
pulses emitted by your camera's built-in flash each time it
flashes. (Many digital cameras emit more than one pulse.)
4. Look at the DF200 Flash On/Off and Mode Switch (10).
§
If your digital camera flash emits only one pulse - slide
the DF200 On/Off and Mode Switch (10) to the "1"
position. Proceed to Step 6 .
§
If your digital camera flash emits two pulses - slide the
DF200 On/Off and Mode Switch (10) to the "2/N " position.
Proceed to Step 6.
§
If you cannot determine the number of pulses emitted by
your camera's built-in flash proceed to Step 5 for further
instructions to profile your flash.
5. If the number of flash pulses cannot be determined:
i. Slide the Flash On/Off and Mode Switch (10) to the
"DETECT" position.
ii. Take a flash shot with your digital camera. (Make sure the
digital camera flash fires.)
iii. Shortly after the camera flash has fired, the green "detect"
LED indicator (15) should illuminate for approximately two
seconds indicating that the DF200 has "learned" the flash
profile of this digital camera. If the green detect indicator
LED does not light up, switch off the DF200 and repeat the
prior two -step procedure.
iv. After the DF200 has successfully detected your digital
camera's flash, slide the DF200 switch (10) from "DETECT"
to "2/N". (One detent position to the left.)
v. The DF200 has now "profiled" your digital camera flash and
is now synchronized with it. Try a few sample shots.
Important note: If the DF200 flash is switched off it will
"forget" the profile for your camera. Turn on the DF200
and repeat the profiling procedure (step V). To use your
DF200 with a different digital camera, turn the DF200
off and repeat the profiling procedure, if necessary.
6. Next, adjust the zoom position of the DF200 flash head to
match the field of view of your digital camera. Refer to the
Distance Table (14) as a guide. If your digital camera does
not have an optical zoom lens, try the MID position.
7. Next, set the DF 200 power level. Depending on the lighting
conditions and distance to your subject, the power of the
DF200 can be set to four different power ratios: 1 (full), 1/4
th
th
1/8
, or 1/16
power. Based upon the zoom setting and
distance to your subject, use the distance table to select a
suitable power level. Take a few shots to perfect your settings.
8. Now, you are ready for digital flash photography.

Hold (Manual Standby) Feature
The DF200 is a slave flash, triggered by your cameras built-in
flash. In a situation where other cameras are present it is
possible that your DF200 flash may be triggered by another
cameras flash. You may prevent this by using the DF200's
hold feature. Press the hold button (11) to suspend the
operation of the DF200 temporarily.
When the hold button (11) is depressed, the green detect
indicator LE D (15) will illuminate, indicating that your DF200
is now temporarily inactive. While on hold, the green LED will
remain a steady green. The DF200 will not respond to any
flash trigger, either intentional or not.
To resume operation, depress the hold button (11) again and
the green detection indicator (15) will cease to illuminate. The
DF200 is now ready to resume normal operation.
Power Output (Power Ratio Switch)
The flash output can be adjusted manually to prevent under
or over-exposure. The power of the DF200 flash can be set
adjusting the "Power Ratio" switch to four intensities: 1 (Full
power), 1/4, 1/8, or 1/16 power. Use this table as a guide:

Bounce Flash
When you take a flash photograph, sometimes a strong
shadow will appear behind the subject as a result of a direct
flash. To minimize or eliminate this shado w, tilt the flash head
upward to reflect the flash off of the ceiling or a wall.
The flash head is adjustable from 0° to 90° vertically. There
are detents (click-stops) at several positions including 30°,
45°, 60 °, 75 ° and 90° positions. The flash head may be
rotated 330° horizontally for additional flexibility.
§
The effectiveness of a bounce flash is dependent upon
distance and the condition of the reflecting surface. The
angle of the flash must be set properly to achieve the best
possible lighting effect. Normally, when a flash is bounced
against a surface, it loses 2-3 apertures of light (f-stops),
even if the surface is white.
§
Exposure in bounce lighting is a factor based upon
t h
,
distance, first from the flash to the reflected surface, then
to the subject and finally back to the camera.
exposure will vary with camera aperture setting, the
distances involved, and quality of the reflective surface.
Experiment to derive the best results.
