   Figures csplayed when ncreasing flash output level
   When “OF” is shown on the LCD display, it means no flash output and flash firing is turned off.

   Number of flashes / Firing frequency = Shutter speed
   For example, if the number of flashes is 10 and the firing frequency is 5 Hz, the shutter speed should be at least 2 sec.
   Note:
   •  Stroboscopic flash is most effective with a highly reflective subject against a dark background.
   •  Using a tripod and a remote switch is recommended.
   •  Aflash output of 1/1 or 1/2 cannot be set for stroboscopic flash.
   •  Stroboscopic flash can be used with “buLb”.

Advanced Application

• Bounce Flas
  By pointing the flash head toward a wall or ceiling, the flash will bounce off the surface before luminating the subject. This can soften shadows behind the subject for a more natural-looking shot.
  This is called bounce flash.
  To set the bounce direction, hold the flash head and tum itto a satisfying angle.• If the wall or ceiling is t0o far away, the bounced flash might be too weak and result in underexposure,
  • The wall or celling should be a plain, white color for high reflectance.
  • If the bounce surface is not white, a color cast may appear in the picture.
•  Creating a Catchlight
  With the catchight pansl, you can create a catchlight n the subject oyes o add lfe o the facial expression.
  Pointthe flash head upward by 90°
  1 Point the flash head upward by 90′.2 Pull out the wide panel. The catchlight panel will come out at the same time.
  3 Push the wide panel back in.
  • Push in only the wide panel.
  • Follow the same procedures as for bounce flash.
  • Point ihe lash head siraight ahead and then upward by 90″ The catchight il not appear f you swing the flash head left orright.
  • For best catchight efect, stay 1.5mid. 9t away from the subject
• Using the Wide Panel
  Pull out the builtin wide panel to enlarge the flash lighting range, so as to get more softened and natural lighting effect.
  Pull out the wide panel and place it over the flash head as shown. The flash coverage will then be extended to 14 mm.
  • The catchiight panel will come outat the same time. Push the catchlight panel back in.
