Flash
*Flash strength
The flash on the IS-1 uses a new exposure control
system. This flash system combines advantages
of both "flashmatic", employed in compact
cameras and "auto flash" which is employed in
SLRs. Flashmatic emits full - strength flash while
the camera automatically adjusts the aperture
level for proper exposure. In most cases this is
an effective system. However, when the subject is
at extremely close range, subjects tend to be over
exposed, and the background too dark because
the aperture has been adjusted to its most narrow
setting. On the other hand, auto flash controls
the amount light emitted by the flash. This system
decides exposure by measuring reflected light.
But, depending on the background, exposure for
the main subject can be affected. For example,
with a white background, the subject may appear
too dark due to the level of reflected light
received through the lens. The reverse is true for
a dark background.
The IS-1 employs a combination of aperture
adjustment and flash strength to give you perfect
exposure every time. That means that the effects
of background lighting and distance-to-subject
are both accounted for.
High Function Flash G40 (Optional)
The G40 is a dedicated flash for the IS-1 (GN131
ISO 100 • ft). It is designed for professional flash
photo - effects such as bounce, multi-flash and
Follow-synchro.
Bounce photography uses indirect lighting of
subjects by reflecting flash light off of a ceiling
or wall. With straight flash photography a strong
shadow often appears behind the subject. By
bouncing, you can obtain a soft, well-balanced
lighting effect on the entire subject. You can also
use the built-in flash together with the G40 for
additional affect.
Multi-flash emits the light several times in one
exposure. With this flash mode, continuous move-
ment, such as a golf swing, can be photographed
sequentially in one frame. It's a multiple exposure
with flash.
With Follow-synchro mode, the flash fires at
the final point of slow synchro. For example, the
tail-lights of a moving automobile can be
expressed.
When the IS-1 is equipped with the tele-
converter lens (x 1.5) or the wide - converter lens
(x 0.8), the built-in flash cannot be used. We
recommend you to use the G40 for such cases.
