Bounce flash
Using the flash unit with a wall directly behind the subject produces strong
shadows on the wall. By directing the flash unit at the ceiling you can illuminate the
subject with reflected light, reducing the intensity of the shadows and producing a
softer light on the screen.
Rotate the flash unit upwards or to the left and right while
pressing the bounce lock-release button.
