Can't Adjust Power of Flash

I have a SB-900 which I'm using with the cactus v6 in an off-camera mode. For some reason regardless of what power I adjust the cactus master (in TX mode) the SB-900 doesn't seem to adjust accordingly (even though the power on the cactus in RX mode adjust based on the TX transmitting unit). Are there any recommended solutions?


  • Have you set the SB-900 to TTL mode and selected the Nikon SB-900 profile on the V6 in RX mode?
