The flash ratio is then set for each ID. r The flash ratio can be set only when the camera is an EOS-3. . The flash ratio cannot be set with an EOS EIan II/IIE, EOS 50/50E, EOS Rebel G/500N, EOS IX or EOS IX1/IX Lite.
www.orphancameras.com Wireless Multi-Flash E-TTL Autoflash Operation In the example shown for "MultiFlash Flash with a Uniform Output, " the lighting balance (flash ratio) was adjusted by PIacing the slaves at different distances to the subject. However, with "Multi-Flash with Slave ID and Flash Ratio Settings," the flash ratio can be adjusted without moving the slaves. The flash ratio can be adjusted from 8:1 to 1 and from 1 to 1:8 in half-stop increments.
www.orphancameras.com Wireless Multi-Flash E-TTL Autofl ash Operation (1) Setting the Slave ID With the wireless control of multiple slaves, you can set the flash ratio and specify the main flash and frll flash by assigning a slave ID. There are three IDs: A. B. and C. The ST-E2 can control slaves A and B. When the flash ratio control lamp is lit, the C slave does not fire. {f :::*,'i:".n,1"r* T,:H""s+: E2.
