EXPOSURE

Automatic Exposure Mode

Exposure refers to the amount of light which strikes

the film, and is controlled by a combination of

aperture size and shutter speed. The correct amount of light, called correct exposure, depends

on the film speed (indicated on the film package,

e.g. ISO 100 or ISO 200).

The automatic exposure function automatically sets

the correct exposure. The IS-3000 employs three types of automatic exposure modes: (1)

programmed auto-exposure, (2) aperture-preferred auto-exposure, and (3) shutter-preferred auto- exposure.

With programmed auto exposure, the camera automatically selects the most suitable combination

of F stop and shutter speed for the existing lighting

conditions. This lets you concentrate on composing

your shot and releasing the shutter at just the right time.

With aperture-preferred auto, you select the desired F stop, and the camera automatically selects the

correct shutter speed. Aperture-preferred auto

gives more artistic freedom of expression and

creativity by selecting a desired F stop to control

the blur of the background.

With shutter-preferred auto, you select the shutter speed, and the camera automatically selects the F

stop. By changing the shutter speed, you can freeze a fast-moving subject or blur it to convey a

sense of motion.

Program Chart (Standard Photography Mode)

The following program chart is for 35mm wide-

angle and 180mm telephoto focal lengths.

According to the focal length, the camera's program

itself changes. When the subject is brightly lit, the F

stop and shutter speed change simultaneously. When the lighting is darker, the aperture opens fully and the shutter speed changes to match it.

In the standard photography mode (refer to p. 14), if

the built-in flash has been flipped up, it will automatically fire in dark lighting conditions. The

shutter speed will be fixed at 1/100-sec.
