Accessory Slave Flash, Lens Accessories

ACCESSORY SLAVE FLASH

If you use the camera built-in flash as the master, you can trigger a second slave flash to provide better artificial light when needed. To do this, you must use an accessory flash that has a slave feature built in. The flash from the camera must be aimed or bounced towards the accessory flash's slave sensor, or other fiber optic sensor. This will trigger the slave to fire in sync with the master flash.

When using an accessory slave flash with fiber optic cable, it is recommended to black out the internal camera flash. The internal flash is located near the camera lens and can contribute to backscatter by illuminating floating particles close to the lens port or a shadowing effect caused by the lens port.

If the sensor of the fiber optic cable is attached to the outside of the housing directly above the internal flash and taped over with black tape–it will block out the light from the internal flash but transmit the light pulse to the external slave flash.

Fantasea Line offers the following underwater slave flashes compatible with this housing:

∙Remora Flash (#6117)- Features a guide number of 20 and therefore compatible for both macro and wide angle photography. The Remora features a variable output control and a Y-S Mount which enables mounting a focus light on top of the flash, thereby eliminating the need for an additional arm.

∙Nano Flash (#6115)- Features a guide number of 12 and therefore useful mainly for macro and general photography. The Nano Flash offers 3 output levels.

∙Complete Lighting Sets- Include one of the slave flashes mentioned above, a tray & arm system, fiber optic cable, padded housing bag and a focus light.

Note

Be sure to use a slave flash that has the ability to ignore the built-in pre-flash in

digital cameras, and synchronizes with the shutter release.
