AUTOFOCUS ASSIST LIGHT
In low light situations, a cameras’ auto focus system can have difficulty locking focus on the subject.
When the ambient light level is low, the ProMaster FL1 flash emits a red autofocus assist beam when the
camera’s shutter release button is pressed halfway. This assist beam will help your camera’s autofocus
system to achieve focus lock.
Not all camera’s autofocus modes work with an external autofocus assist beam for focusing. Please
check your camera’s instruction manual to find out more.
"Red-eye" occurs when the light from the flash reflects off of the retinas in your subject’s eyes.
Many cameras include a "red-eye reduction" feature. When this feature is activated, the camera will
instruct the flash to fire pre-flashes before the picture is taken to help eliminate the red eye effect.
The ProMaster FL1 flash supports your camera’s red-eye reduction function. Please refer to your
camera’s instruction manual for details on how to activate it.
