Wireless Flash Photography (B) (B) 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. Bounce (B) Bounce Camera with Master (A) 1. Set up the main flash unit - To prevent the strong shadows a direct flash would produce, the main flash was bounced off a wall near the camera to soften the lighting. Bounce (A) Bounce Camera with Master (A) 2. Add an auxiliary flash unit - Remaining shadows were weakened by bouncing an auxiliary flash (A) off another wall to hit the subjects from a direction opposite that of the main flash unit. Bounce (A) Bounce Camera with Master (A) 3. Add another auxiliary flash unit - To improve gradation and contrast, another auxiliary flash unit (B) was set up behind the subjects. Its light was bounced off the back wall to accent key details of the image. Camera with Master (A) A:B=1:2 Bounce Sample Photo Analysis - Three flash units provided illumination. 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. E-TTL/E-TTL II Wireless Autoflash Control 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 consistently correct exposure. The EOS 7D features the wireless autoflash control with its built-in flash. The EOS 7D, also features a modeling (preview) flash is available by pressing the depth-of-field preview button directly, or when Speedlite 580EX II is used with any other current EOS SLR. Even with multiple Speedlites, the modeling flash fires according to the ratios you have set. E-TTL/E-TTL II wireless autoflash also supports most other Speedlite features, such as FE Lock, FP Flash, Flash Exposure Bracketing/Compensation, and Stroboscopic Flash. Finally, for macro shooting, the Macro Ring Lite MR-14EX and Macro Twin Lite MT-24EX can be used as master units as well. 42 SPEEDLITES Amazing Flash System Canon offers a full range of Speedlite flash units compatible with EOS System cameras for a wide variety of applications and photographers' needs.
