6.4 -DAYLIGHT SYNC FLASH -SLOW-SPEED-SYNC PHOTOGRAPHY When the background of your photo is brighter than your subject, a backlit situation occurs. Under these conditions, your subject will be underexposed and appear darker if you take pictures according to the value the exposure meter indicates. If you allow the camera to compensate the exposure automatically, overexposure may occur. To compensate for this condition, your subject needs additional illumination to be balanced against the background. Using the Daylight Sync Flash in the Programmed TTL Auto Flash mode supplies the needed light for a beautifully balanced subject. • If the background is too bright to require a flash, the flash unit may not discharge. If a flash is still desired, use the manual flash mode. When using a normal flash to photograph a subject in a night or evening setting, the background will appear very dark because a normal flash light cannot sufficiently light it. However, it is possible to balance both subject and background by using the flash to properly expose the foreground subject and a slow shutter speed to expose the low light background. • With the Z-1/PZ-1, slow-speed-sync TTL Auto flash is possible in the Hyper Program AE, Shutter-Priority AE and Hyper Manual exposure mode; with the Z-10/PZ-10, SF7/SF10 and SFX-series in the Manual exposure mode. 18
