Aperture preferred auto allows greater manual control for more artistic freedom and expression.

The shutter speed will automatically adjust up to 172000 second with the aperture fully opened. As the brightness increases from there, the aperture will begin to adjust. The reasoning behind this is that with a larger (more open) aperture, the depth of field is reduced. At the same time, shutter speed is increased to prevent camera blur. tions a professional photographer will adjust for exposure compensation or select manual shooting mode. The exposure compensation level chosen by a professional is usually based on experience. The night scene mode of the IS -1 will automatically adjust exposure compensation for suitable night scene photography. For example, when shooting a subject with a night scene as its background, the use of flash is often desireable. Should that be the case, the camera performs the most suitable exposure compensations for both the subject and the background. The shutter speed may be very slow (up to 4 seconds with ISO 100/15 seconds with ISO 25). To prevent blurring, the camera should be set firmly in position (with a tripod for example). Fill-in flash Under strongly backlit conditions the exposure may result in a subject that is too dark. The IS -1 prevents this unwanted result through ESP photometry and spot metering. However, should backlighting be extreme, this is not always effective enough to compensate. For that, the IS-1 employs a Fill-in flash whereby the subject is lighted by a flash emission. This lights your subject, while maintaining proper exposure for the background. Fill-in flash provides an iueresting "catchlight" effect where the color of your subjects eyes appear vivid and aglow.

That is usually because the camera's automatic exposure function works on a standard exposure ratio.

The IS -1 employs three meterings: (1) ESP light metering, (2) centerweighted average light metering, and (3) spot metering. [. . . ] *While using the flash, the shutter speed and aperture setting displays will blink to warn you that the subject is out of flash range. *When the subject moves too fast or is not positioned within the autofocus frame in the center of the viewfinder, the camera may not focus properly. *It is sometimes difficult to attain an accurate distance measurement of subjects that have a low reflection ratio, such as navy blue or black or subjects outside AF illuminator range (1. 2-4 m/3. 9-13. 1 ft), even though the autofocus indicator appears in the viewfinder. -- 68 -- The shutter will not release. *The camera may not be in focus. *The shutter will not release if a rewound film cartridge is still inside the camera.
