Using The Camera Built-In Flash - Fantasea Line FRX100 III Housing Instruction Manual

USING THE CAMERA BUILT-IN FLASH

1. The Sony RX100 III has a built-in flash capable of illuminating nearby underwater subjects. For
stronger lighting, illuminating subjects that are farther away, avoiding backscatter, eliminating
shadowing effects and photographing in deep water, an accessory slave flash is recommended. For
further information, please refer to the section "External Flashes".
2. In order to make use of the built-in camera flash, remove the Fiber Optic Cable Plate from the
housing. Insert your fingers beneath the adaptors installed inside the plate and push the plate
upwards till it is removed from its slot. Make sure the fiber optic cable plate is secured to the
housing by the dedicated secure line in order to avoid losing it during the dive.
3. The removable flash diffuser included assists with softening the built-in flash output, increasing its
angle of coverage and decreasing the amount of backscatter in the images (the unattractive
snowstorm effect of the flash reflecting off suspended particles in the water).
a. In order to install the removable flash
diffuser, hold and align the diffuser ring
against the housing lens port with the
diffuser pointed horizontally
(image #15).
b. Gently push the diffuser ring against the
housing lens port till it clicks.
c. Once the diffuser ring has been
installed on the lens port, turn the ring
till the diffuser is positioned on top of
the lens port. When reaching the
proper position, the diffuser ring clicks once more.
d. Attach the flash diffuser quick release secure string to the other side of the string connected
to the housing in order to avoid losing the flash diffuser underwater.
e. In order to remove the flash diffuser from the housing, first turn the diffuser ring till the
diffuser is pointed horizontally. With the diffuser pointed horizontally, gently pull the ring
out of the lens port.
f. During the dive, in order to disable the flash diffuser, the diffuser ring can be turned until the
diffuser is pointed downwards or aside. This eliminates the need to completely remove the
flash diffuser in order to eliminate it.
4. It is best to set the camera flash mode to "Flash Always" as artificial light is required in most
compositions for the purpose of color and light reproduction. This will ensure the built-in camera
flash fires on every image taken regardless of ambient light available. Please refer to the Sony RX100
III instruction manual for further instructions regarding such settings.
5. Turn the Flash Pop-Up dial counterclockwise in order to pop up the camera built-in flash.
