Using a light meter and a Nikon SB900 triggered with a v6ii
Since using Cactus V6II triggers I have difficulties with proper light measurements using my Sekonic L-358.
With daylight I get proper measures, but in the evening I only get f2 with whatever setting the flash is firing.
Time to do some rigorous testing.
First test, wireless triggering a Nikon SB900 in TTL. I only get f2 on my light meter.
Second test, triggering a Nikon SB900 in TTL using a PC sync cable between the cactus and light meter. The cactus is triggered, but no flash.
Third test, wireless triggering a Nikon SB900 in Manual. I only get f2 on my light meter.
I realized I hearing the flash popping twice. So we have a pre-flash being measured by the light meter, despite setting the flash in manual mode. Damn......
Fourth test, wireless triggering a Yongnuo YN560 IV, a full manual flash. I get a good reading!!
Fifth test, triggering a Yongnuo YN560 IV using a PC sync cable between the cactus and light meter. Yes! A good reading.
Final test, wireless triggering a SB900 in manual. This time I set the RX Cactus profile on manual flash.
Bam!! Good reading!! I can now even trigger with a PC sync cable.
So, when using a light meter and Nikon SB900's, the Cactus V6II must be set on a manual profile and can only act as a trigger.
A bit of a disappointment not being able to use remote power control on flashes like the SB900's.
