5. Bounce photography
When you are taking photographs indoors, you can aim the
flash unit at the ceiling or at a wall - instead of directing theflash directly at the subject - and achieve a soft lighting effectwhen the light is ref lected.
The flash head of the unit may be set at the 0o,60o,75" and
90' click-stop positions.
o Auto bounced light photography
(1) Once you have decided on the subject for your photograph,
point the f lash head at the desired bounce angle.
l2l Auto operations are generally the same as those for auto
photography.
The auto coverage distance for bounced light must be
greater than the total distance between the f lash unit and
reflected surface and between the reflected surface and the
subject. This means that a low f-number is normally ap-
propriate.
(3) You will achieve better results if you perform a check with
a test f lash before actually taking the photos.
o Manual bounced light photography
A great deal depends with manual bounced light photography
on the distance and conditions involving the reflection surface
(color, reflectance, etc.) and so it iswiser to proceed after taking
a test photo.
Bounced light precautions
(1) Remember that the subject and its surroundings may
change color when you are taking pictures in color because
of the effects of the color of the reflecting surface.
Ql Take care not to allow the subject to enter directly into the
range of the bounced light angle with bounced light photo-
graphy.

I Cautions
(1) Avoid using the flash unit in temperature extremes (over
40oC. under -10"C) since these will adversely affect the
internal parts.
Ql Never attempt to disassemble the unit if it breaks down.
This could be dangerous.
(3) Do not exposure the unit to humidity or rain or sea water.
