Wireless Flash Photography - Canon EOS 7D Brochure

Wireless Flash Photography

Canon's EX series Speedlites have made multiple-flash photography simple, wireless
and automatic. Using the Speedlite 580EX II, Macro Speedlite MR-14EX, Macro Twin
Lite MT-24EX, or the Speedlite Transmitter ST-E2 as a master unit, wireless signals
are transmitted to an unlimited number of Speedlites 580EX II or 430EX II, creating
myriad possibilities for lighting, no matter the location. For the ultimate convenience,
the EOS 7D has an Integrated Speedlite Transmitter, which has the transmitting
features of the Speedlite 580EX II, allowing users to wirelessly control EX series
Speedlites and doing away with the need for an external master unit.

nation. The light from the master flash unit (A), a Speedlite
580EX II mounted on the camera, was bounced off the wall
to soften its intensity before reaching the two violin makers.
A slave 580EX II (B) was set far enough away on a desk to
be pointed directly at the statue, and another 580EX II (B)
was used to light up the overall office. Based on the results
displayed on the camera's LCD monitor, the brightness of
the master flash unit was halved to achieve natural lighting.
Up to three groups (for main, fill and background)
of slave units can be set up for comprehensive
control of flash lighting. The Speedlite slave
units can be assigned to group A, B, or C, with
output ratio between groups A and B adjustable
from 8:1 to 1:1 or 1:1 to 1:8. The output of the
group C can be adjusted through flash exposure
compensation. Superb lighting is simple thanks
to the E-TTL/E-TTL II autoflash system which
controls the total flash output to ensure consis-
tently correct exposure. The EOS 7D features the
wireless autoflash control with its built-in flash.
