Optical Triggering Sensitivity
Apologies if this has been discussed before. I've done a lot of searching on this board and haven't found any info regarding my problem.
I'm trying to trigger a Canon 430exII using a Cactus V6 in RX mode, set to optical trigger mode: 1st flash (S1) or Main Flash (S2).
I can get it to trigger the flash, but only when i place the receiver's eye about 3 inches from my strobe. Any further away and the flash doesn't get triggered. I have 2 other Cactus V6 units and they all behave similarly.
Is there some sensitivity setting that i need to engage or change to get these Cactus units to fire without putting them nearly touching with a bright strobe light? I'm not trying to do any thing fancy like HSS or TTL...just a simple optical trigger.
Any help is much appreciated!
