When the flash is charged and ready, the ready lamp at the rear of the unit glows. When the flash charging time exceeds 30 seconds, replace the batteries. 1. Insert the batteries as shown in the diagram in the battery chamber. 3. Close the battery-chamber door. 10 11 PF2500D_English_C404. qxd 2004. 05. 12 03:33 PM Page 12 GETTING STARTED Mounting the flash Slide the flash mounting foot firmly into the camera's accessory shoe until it stops. · The flash locks into place automatically. · If the camera's built-in flash is up, lower it before mounting the flash unit. Metering-mode switch Select the flash metering-mode. · For the Maxxum/Dynax series cameras, ADI flash metering is available with the ADI compatible cameras and D series lenses. · For the DiMAGE series digital cameras, ADI flash metering is available with the ADI compatible digital cameras when the ADI flash metering-mode is set with the recording mode menu. · When using a close-up diffuser, a filter that increases exposure (red 25, neutral density), or bounce flash, set the metering mode to TTL. Bounce flash reflects the light from the ceiling to create soft diffuse illumination. ADVANCED OPERATION BOUNCE FLASH The section describes advanced flash photography techniques and accessories. . Bounce flash Normal flash (Continued on next page) 22 23 PF2500D_English_C404. qxd 2004. 05. 12 03:33 PM Page 24 BOUNCE FLASH Tilt the flash towards the ceiling. · The flash has a click stop at 60°. The bounce head can be set in any position between 0° and 90°. Adjusting the Bounce Angle The angle of the bounce head is important. If the bounce angle is too low, the subject will be illuminated by both directly with the flash and indirectly with the reflected light from the ceiling resulting in a harsh and unevenly lit photograph. Determine the bounce angle in reference to the distance to the reflective surface, the distance from the camera to the subject, and the angle of view of the lens. · With bounce flash, using ADI metering can result in incorrect exposure. The color of a surface will affect the color of the flash illumination. High ceilings or highly reflective surfaces such as glass are not suitable for bounce flash. Correct Incorrect Determine the angle in relation to the table at right. Focal length of lens 70mm minimum 28~70mm 28mm maximum Bounce angle 45° 60° 75°, 90° 24 25 BOUNCE FLASH PF2500D_English_C404. qxd 2004. 05. 12 03:33 PM Page 26 AF ILLUMINATOR In low-light or when subject contrast is low, the autofocus system may not be able to focus. In these conditions, the flash's AF illuminator will active to aid the AF system when the shutterrelease button is pressed partway down. OFF-CAMERA CABLES The use of the optional off-camera cables allows the flash unit to be placed to the left or right of the subject to create attractive side lighting. Up to four flash units can be connected. · The camera's AF illuminator is disabled when the flash AF illuminator is in use. · The AF illuminator is disabled when using the continuous AF mode. · The AF illuminator may not operate with lenses with focal lengths greater than 300mm. The illuminator is disabled when the flash is used off-camera, or with the AF macro-zoom 3X-1X lens. [. . . ] Battery performance can be restored by using the flash a few times or turning the flash unit on and off several times. · If lithium batteries become hot due to high temperatures or repeated use, an internal safety circuit shuts them down. If battery performance drops while using the batteries, recharge them. · Depending on the time elapsed since the battery was manufactured, the flash performance for new batteries may differ from the values shown in the technical specification section. Maintenance · Clean by wiping with a soft, clean cloth. [. . . ]
