Program chart (portrait mode)
The chart shown below is a program chart for portrait mode.
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. That means that the distanced background will be more out-of-focus. At the same time, shutter speed is increased to prevent camera blur.

Night scene mode
When shooting night scenes you may sometimes be disappointed with the result. That is usually because the camera's automatic exposure function works on a standard exposure ratio. In such situa-
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.
