I have an extra Metz 20 C-2 flash, which i was thinking to use it as a back light.
So how can i make it flash at all time?
Thanks in advance for your kind advice.
Maybe yes, maybe no, depending on your set-up. I suspect you might be happier if you use an optical slave if you're not using a mani flah wirh digital pre-flash, or just a very long PC cord. Alternatively, use a radio trigger.
