SETUP 03 6ft 01 14ft 02 6ft 01 Background 02 Camera Right Full A flash is placed 14ft away to illuminate the water behind the subject and is controlled from the secondary remote channel of the flash-RMT2. 03 (1+2) Left/right balanced With the flash off behind the subject, we focus on setting the two flashes slightly in front and on each side. Here, the right flash was set to a ratio of 8 while the left flash was set. Getting Creative Two flashes are 6ft away on each side of the subject. Here is the result of all three flashes firing at equal power of 16. 36 Because we were able to change the Flash Ratio from our on camera flash we were able to quickly experiment with different ratios until we achieved the desired result. wireless ratio control The light ratio represents how much stronger one light source is compared to another. A direct light source could be twice as strong as that same light from a reflected surface. Therefore, we would have a 2:1 ratio of direct light vs. reflected light. Wireless Ratio Control allows us to control the volume of light that is emitted from each flash or set of flashes wirelessly. Each set can include more than one flash. This is easy to do and allows us to set the ratio of the control flash on the camera plus two more flashes or sets of flashes. Being able to control all of our flashes from one source saves time while also allowing for more creativity. Final Shot In this three flash setup, we want to add some dramatic lighting to the subject's face. We could move one flash further or closer to the subject adjusting the amount of light hitting one side of her face but that would be cumbersome. Instead we used Wireless Ratio Control from the flash on our camera. F7.1, 1/160 SEC, ISO 125 Off-camera Flash Basics What is it? Dynamically control the volume of light that is emitted from each flash in a multiple light setup. 01 0:1 1:2 1:1 How to use it? Set all your flashes in wireless mode (WL). Set your flash on the camera to control (CTL) and the other flashes to one of the wireless zone settings (RMT1 or RMT2). Then set the Ratio Control in the "control" flash settings. Here you can set the ratio of the control flash on the camera plus two more flashes or sets of flashes. (Refer to Instruction Manual for more details) Where to use it? Use this when you want to control the amount of light emitted from your wireless flashes. 37
