Olympus Infinity Super Zoom 330 - Manual (Page 61)

Spot metering
Among methods for measuring the amount of light, the most widely used is the "center - weighted average light
metering system" (Fig. A). This system gives excellent results when taking ordinary shots; however, when there
is an extremely bright or dark area in the frame, a center - weighted average light metering system may not
automatically set the best exposure. When taking a portrait for example, if the background is too bright, the
subject will be dark, and vice versa. The sophisticated light metering system used in the Infinity Super Zoom
330 which is used to obtain proper exposure in this situation is called "spot metering". Spot metering (Fig. B)
measures and calculates the correct exposure only from the brightness in the central section of the frame.
This makes spot metering very convenient when the subject is back lit, side lit, or spot lit. Even when the
subject looks dark and does not stand out from the background, your photographs will be exposed properly.
To make white objects look very white, use spot metering and then operate exposure compensation button to
the (+) direction, to make black objects look very black, use spot metering and then operate exposure
compensation button to the (-) direction.
Double exposure
"Double exposure" refers to a technique in which images are superimposed by releasing the shutter twice
without advancing the film.
In the case of the Infinity Super Zoom 330, you can easily take double exposures by pressing the DRIVE button
inside the mode cover.
By doing this, even when the shutter is released, the film won't advance to the next frame until the shutter has
been released for the second exposure. Used together with the spot metering function, you can take extra
special - effects photographs, with the same face but with different expressions appearing twice in the same
photograph, for example. We recommend combined use of exposure compensation and the flash for
applications of this type.
