FLASH EXPOSURE COMPENSATION
Even though the macro ring flash exposure is fully automatic, it is
still possible to control the lighting intensity emitted by the ring tube
by way of enabling the flash exposure compensation on the DSLR
camera body which allow the flash exposure adjustment up to +/-3
stops in +/-0.3 stops increment*.
When the flash exposure compensation is activated on the DSLR
camera body, the macro ring flash will emitted the lighting amount
according to the flash exposure adjustment.
*For detail operating instructions on the flash exposure compensation setting,
refer to your DSLR operating instruction manual.
RED EYE REDUCTION
Red eye reduction is a feature incorporated in the camera body
which helps to reduce the occurrence of red eye when shooting
under low lighting or complete darkness.
When red eye reduction is activated on the DSLR body, the flash
unit will activate a series of preflash before the main flash to reduce
the possibility of red-eye occurrence during digital photography.
For detail operation on this feature, refer to your camera body operation instruction manual.
