BOUNCE
FLASH
Bounce
flash
is recommended
if you
want gentle diffuse lighting without prom-
inent shadows.
Point the flashlight
at the
ceiling
(white for colour
photography
to
avoid undesirable
colour variations
in the
exposure).
The reflector
can be moved
through an angle of 180° to the left, 160°
to the right and 90° upwards.
The reflector
can be moved
upwards
if
you rotate the rotating reflector
control 6.
We
recommend
that
you
only
make
bounce
flashes
exposures
when
the
computer
is switched
on (computer
posi-
tion with the greatest
distance
range).
Ensure
that the distance
from the flash
unit via the reflective
ceiling to the object
is not greater than the maximum
permitted
distance
range of the computer.
This
can be checked
easily with computer
ready lamp
19.
For manual bounce flash, the
aperture should be opened one stop further than indicated
on the aperture scale on
the unit for direct flash. For example: f4 instead of f5.6 at a reflector position of 45°. If
the reflector
is in a position
between
60° and 90°, the aperture
should be opened
two stops more, i.e. f4 instead of f8. Clearly, this whole process
depends
to a cer-
tain extent on the type of wall or ceiling. The corrective
action mentioned
above
should only be used in normal situations
(white ceiling or wall).
Diffuse light can also obtained
with the Philips accessory,
bounce panel PFB 507.
SUBFLASH
Some situations
require a combination
of direct and indirect flashlighting,
e.g. por-
trait photography.
These are combined
perfectly
in this flash unit.
The main flash can be rotated in all directions
to provide indirect lighting for an ob-
ject via a wall, ceiling or other reflective
surface,
whilst the subflash
is pointed di-
rectly at the object. Use of this subflash
softens
shadows
on the object.
The subflash
is switched
on and off with switch
25.
At full power it has a guide number of 9, if the main flash is not directed at the sub-
ject.
WIDE ANGLE
- NORMAL
- ,TELE SETTING
The light beam of the flash unit can be widened
or narrowed
with the built-in wide
angle diffuser or tele refractor
in the flash unit. These can be used to modify the light
beam from your flash unit to the various lenses of your camera. The indications
W,
Nand
T are located on the side of the unit.
W means wide angle and is for use with wide angle lenses from 28 mm to 50 mm.
N means normal and is for use with lenses with a focal length from 50 mm to 135
mm.
T means tele and is for use with tele lenses from 135 mm and longer.
The wide angle diffuser or tele refractor can be positioned
in front of the reflector by
means of rotating control 7.
If the reflector
is rotated, the selected
light beam setting is also rotated.
The W-N-T sliding control 13 should be set in a position
which corresponds
to the
beam setting in use. The corrected
maximum
distance
to the subject can then
be
read off normally
from the distance
scale 12.
USING COLOUR
FILTERS
The light beam can be coloured
with the colour iilters supplied.
These filters should be inserted
in the colour filter compartment
8.
The colour filters can also be used in combination
with the tele refractor or the wide
angle diffuser.
.
Clearly, the use of colour filters affects the lighting. The aperture
should then be set
approx.
1 to 1.5 stops further open.
HINTS AND PRECAUTIONS
Flash units are not only used in photography
when ordinary
lighting is insufficient
but can also be used when lighting is normal in order to prevent shadows
appearing
in the final exposure.
You can read books on this subject but the most important
thing is to experiment
with your camera and flash unit until you have discovered
all
the possibilities.
By using the slave unit P 100-SU (available
separately),
you can
use several flash units simultaneously.
Power pack PFB 104 (available
separately)
can be used to shorten the interval be-
tween two flashes to approx. 4 sec. for manual control and between
0.5 sec and
4
sec for automatic
control.
The power pack can be connected
to your flash unit via connection
23.
The power
pack is extremely
useful with a camera fitted with a winder or motor drive.
When taking pictures with flash, do not shoot directly at highly reflective surfaces li-
ke-mirrors
or windows.
When you have finished a session of flash photography,
set
switch
14
to the off position.
Remove
the batteries
when the flash unit is not to be used for some time.
Do not try to open or repair your flash unit. This not only voids the guarantee
but
could be dangerous
because
of the high voltage
present.
If your flash unit needs repairing
or does not work correctly,
take it back to your
dealer.
