Know about the best flash triggers
The best flash triggers
allow you to position your speed light far away from your camera, creating new
and exciting lighting set-ups
Using a wireless flash
trigger may be a far better bet. Not only does an honest
radio-frequency trigger offer to 100 meters of range, you'll often use one
transmitter to regulate multiple flashguns separated into several groups.
It’s great for replicating a studio flash head setup, with a
separate key, fill and accent lights. The sole downside is you’ll need a
further receiver for each extra flashgun you would like to include, though some
modern flashguns can pack inbuilt receivers.
Another thing in touch in mind is, unlike an easy cord that
enables all flashgun functions; many low and mid-range wireless triggers can’t
transmit TTL metering or other specialist signals. Consequently, you'll need to
resort to manual flash control, which may be time-consuming.
Finally, wireless flash triggers are usually designed to figure
with one camera brand with remote
camera control, but we’ve included an exception.
Five things to observe out for
Channel hopping
With frequency triggering comes possible interference from other
RF devices. A system with multiple channel options or channel coding will
exclude uninvited waves.
Stand back
All the kits we’ve featured use frequency triggering, which unlike
cheaper infra-red systems, usually provide up to 100m of range without having
an immediate line of sight.
Sync speed
Typically, a flash trigger will enable a shutter speed up to
1/250sec, but top-end systems boast high-speed sync with compatible flashguns,
enabling up to 1/8000sec shutter speeds.
Stay put
Don’t fancy dalliance running between multiple flashguns to line
their power? More advanced triggers will allow you to remotely control flashgun
output from the transmitter.
TTL triggering
A triggering system that wirelessly transmits TTL metering signals
may be a must if you believe the hearth and forget the simplicity of a TTL
flashgun, but these triggers inevitably carry a premium.
