TTL FLASH MODE
TTL Flash Mode | 11
When your flash is mounted to a compatible camera, the ProMaster FL1 flash’s advanced programming
and computerized circuitry will produce the correct exposure using the camera's TTL metering data.
To use the TTL mode, follow the steps below:
(1) The camera should be set to P, Auto, or any priority mode such as aperture-priority.
(2) When you first power the flash unit, it will automatically be set to TTL mode, and the “TTL” indicator
will be visible on the LCD. If the flash has been set to another mode, press the MODE button
repeatedly until the “TTL” indicator shows on the LCD.
(3) Press the shutter release button on your camera halfway to ensure that the camera is communicating
with the flash. The camera’s ISO and aperture setting will be displayed on the flash’s LCD, and a flash
icon will appear in the camera’s viewfinder.
(4) Make sure that the subject is not farther away than the suggested distance indicated on the LCD.
(5) Press your camera’s shutter release button fully to take the picture. An ‘OK’ indicator will show up
momentarily on the LCD. The green OK light will also glow to indicate that a proper exposure has been
attained.
• FOR NIKON flash: The LCD will show TTL, I-TTL or BL depending on your camera model. Please refer to your camera's
instruction manual for details.
• The ISO and aperture indication on this flash provide readouts up to ISO 800 and f/11 in full-stop increments. The
indicator will show the ISO number and f/stop value closest to your current camera settings.
