Modeling flash
Before taking a photograph it is possible to carry out a pre-flash to confirm
shadows of the subject.
After confirming that the READY lamp is on, press the modeling flash
button and the flash will light up for about 2 seconds continuously.
P Note
Using the modeling flash will allow the direction and area of shadows to be
confirmed, however the depth of the shadows will be different from the real
photograph. In bright locations or outdoors shadows cannot be confirmed.
