Flash Strength

The flash on the IS-3DLX employs a new exposure control system that combines the advantages of both "flashmatic," used in compact cameras, and "auto flash," found in SLR cameras. Flashmatic emits a full-strength flash while automatically adjusting the aperture for proper exposure. This

system is effective in most cases. However, subjects

at extremely close range tend to be overexposed, and the background too dark, because the narrowest aperture setting has been selected. Auto flash varies the amount of light emitted by the flash,

and sets the exposure by measuring reflected light.

Depending on the background, however, the wrong exposure for the main subject can be selected. 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-3DLX adjusts both the aperture and flash strength to give you perfect exposure every time, taking into account the effect of the background light and the distance to the subject.

Dual-Strobe Intelligent Flash

The flash of the IS-3DLX is distinguished by two emission tubes. One of the most important functions

of a flash is to distribute light evenly throughout the

frame. When a zoom lens is used, the area that can

be lit by a single flash is determined by the wide- angle focal length. When telephoto is used, the light

is wasted because the light is spread over a wide area. If this wasted light is concentrated on the picture area, however, the working distance of the flash will be increased. Solving this problem is crucial to effective telephoto-flash photography.

The zoom flash system found in some cameras is one solution to this problem. With this system, the distance between the xenon tube — which is the emission source of the flash — and the reflective material behind it is varied according to the focal length of the lens. When telephoto is used, the light from the flash is condensed more intensely. (The

distance between the xenon tube and tne

condenser lens can be varied for the same result.) So why does the IS-3DLX incorporate the dual- strobe system? Because the dual-strobe system can utilize the light more effectively while achieving more

uniform lighting than the zoom flash system is capable of. The zoom flash system also cannot alter the actual shapes of the reflector and the condenser lens. In practice, these two factors greatly affect the even distribution and condensing intensity of light from the flash. The zoom flash sacrifices the effective use of the light's intensity for even distribution. To achieve both optimal condensing intensity and even distribution, Olympus developed the dual-strobe flash system with two sets of tubes

and a reflective backing that are ideal for both wide-

angle and telephoto photography. This makes a powerful, versatile flash with GN 28(130 100·m)/ GN 92 (ISO 100·ft)possible.
