- Page 2 ➢ Never expose batteries to overheating, short-circuiting, disassembling, high pressure, mechanical deformation. Save batteries from high humidity and water. All these circumstances may cause a chemical leakage, electric shock, explosion or fire, which can be dangerous for health. ➢ Remove batteries from TTL Converter before longtime storage. ➢...
- Page 3 Initial Settings ▪ Set and check camera settings before underwater shooting: Set only “Mechanical Shutter” type in camera menu. You also can use “e-Front Curtain Shutter”. But don’t set fully Electronic Shutter by menu, it is not supported by this TTL system. Set Camera mode (“M”, “P”, “A”, “S”...
- Page 4 • Note2: TTL Converter’s special feature “Flash intensity adjustment by camera controls in “Controlled Manual mode” (look the appropriate partition below) is not applicable with YS-D3 DUO, because of the optical signal processing algorithm inside the strobe. But electric input of YS-D3 DUO supports this feature. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ▪...
- Page 5 In normal operation, TTL +/- Flash exposure compensation adjustment is available for underwater photographer through 2 methods: Using “+/-Ev” dial switch on the underwater strobe body (adjustment works for fiber-optical type connection only). Using camera “Flash Exposure Compensation” function. Such adjustment type is recommended as more accurate, and it works for both types of connection (optical / electric).
- Page 6 • Special note for YS-D3 DUO strobe usage: TTL Converter’s Flash intensity adjustment by camera controls in this “Controlled Manual mode” is not applicable with YS-D3 DUO via optical input, because of the optical signal processing algorithm inside the strobe. Although the electric input of YS-D3 DUO supports this feature normally. Underwater Strobe Manual Mode (set by underwater strobe dial switch): Set underwater strobe dial switch to M mode without pre-flashes.
- Page 7 ▪ Shutter high speeds for shooting are available in Manual mode of the system (use “WL” command) in range 1/320 ….1/8000 (and faster, dependently of camera model). All model underwater strobes (excluding Retra Pro MAX) in this case don’t produce a flash, automatically via TTL-converter control. Continuous (Serial) Shooting using underwater strobes ▪...
