the subject and half-press the shutter
release button. Confi rm that the “ ”
mark is visible in the viewfi nder and that
the shutter speed and f-stop are correct
before fully pressing the shutter release
button.
To prevent damage or malfunction,
do not bend the light-emitting section
above 90 degrees.
Bounce lighting is possible simply by turning the light-emitting section
up toward the ceiling,. All other operations are identical to shooting
with direct lighting. However, note that the brightness may drop to
about 25%, though this is variable depending on the color and material
of the refl ecting surface. It is therefore recommended to open up
the aperture (to decrease the f-number as much as possible). The
surface used for bounce lighting should be as white as possible and
its refl ectivity as high as possible. Note that, in color photography, if
the refl ecting surface has a color, the colored refl ection will stain the
subject in that color.
Using the Wide Panel
The RD2000 has a “wide panel” attached
to it.
The fl ash usually covers an area with a
focal length up to 32 mm, and the wide
panel is for use when the lens in use is
a wide-angle lens with a shorter focal
length. Specifi cally, the wide panel makes
the fl ash compatible with a focal length
up to 24 mm.
Operation is easy. All that is needed
is fl ip up the white panel on the light-
emitting section with a fi ngertip and place
it on the lens of the light-emitting section.
Note that the use of the guide panel
decreases the guide number to 14.
Important Note on Successive Firing
To prevent degradation due to overheating that may result from
successive fi ring, it is recommended to pause fi ring for more than 10
minutes after successive fi ring.
