BounceFlash
By pointing the flash head toward a wall or ceiling,
the flash will bounce off the surface before
illuminating the subject. This can soften shadows
behind the subject for a more nature-looking shot.
This is called bounce flash.
To set the bounce direction, hold the flash head and
turn it to a satisfying angle.
16

CatchlightPanel
• If the wall or ceiling is too far away, the bounced
flash might be too weak and result in
underexposure.
•T he wall or ceiling should be plain white for high
reflectance. If the bounce surface is not white, a
color cast may result in the picture.
Using the catchlight panel enables you to reflect
light in a person's eyes and create a more vivid
expression.
3. Push back the [wide
panel]. Shoot using the
same method as bounce
shooting.
1. Turn the flash head
90° up.
2. Pull out the [wide panel].
The [catchlight panel] is
also pulled up at the same
time.
To obtain captivating catchlight in a person's
eyes, shoot within 1.5m of the subject.
Position the flash head towards the front and
90° up. When the flash head is rotate to the
left or right, the catchlight is not very effective.
Zoom:FlashCoverageSetting
