In such cases, remove the flash unit from the camera and position it to obtain a more three-dimensional effect as shown in photo 2. And by using 2 or more flash units, you can create more detailed light conditions as shown in photo 3. When taking this type of photograph with a single lens reflex camera, the camera and the flash unit are most commonly connected by a cable. This flash eliminates the need for a cable to transmit signals to the flash unit by using the light of the flash itself as a signal. The correct exposure is determined automatically by the camera. Normal flash Wireless flash Wireless flash (Lighting ratio control mode) 54 Wireless Flash Range The wireless flash uses a light signal from the flash as a trigger to operate the offcamera flash unit. Follow the points below when positioning the camera, flash, and subject. · Photograph in dark locations indoors. · If you rotate the flashtube using the bounce-flash function (page 36) so that the wireless control-signal receiver points toward the camera, it will be easier for the flash to receive signals from the camera. · Place the off-camera flash within the gray area in the following diagram.

Additional Information Batteries · The battery level displayed on the LCD panel may be lower than the actual battery capacity, due to temperature and storage conditions. The displayed battery level is restored to the correct value after the flash has been used a few times. · Nickel-metal hydride batteries can lose power suddenly. If the low-battery indicator starts blinking or the flash can no longer be used while taking pictures, change or recharge the batteries. [. . . ]
