It is best to mount the BigEye Lens on the EyeGrabber once it is removed from the
housing lens port, as first – it can be most easily accessed this way if you would like to
mount it back on the housing later on during the dive, and second – it protects the
BigEye Lens from being scratched or damaged.

What was the fiber optic cable plate designed for?
When installed on the housing, the fiber optic cable plate and the two adaptors inserted inside it
allow for an easy attachment of up to 2 fiber optic cables to the housing, which enables
integrating two slave flashes in the underwater photo system.
When installed on the housing, the Fiber Optic Cable Plate blocks the internal camera flash, so
only the external slave flash illuminates the subject. This diminishes the effects of backscatter,
as well as eliminates any shadowing effect caused by housing lens port, especially when lens
accessories are mounted on the housing.

What is Backscatter and how do I avoid it with the FP7100?
When there are many suspended particles in the water, especially when visibility is low, the light
of the flash reflects back from these particles, creating backscatter. This problem occurs in
underwater flash photography, especially when the flash is too close to the camera lens (such as
when using the camera internal flash). What you might see is a slight fog, a haze or bright specks
obscuring the picture. The most efficient solution for backscatter is using an external flash and
positioning it farther away from the camera lens. It is best to position the strobe in an angle that
differs from the angle of the camera lens, so the light of the flash bounces back to a different
direction than the direction of the lens.

What is the anti-glare hood, included with the housing, designed for?
When installed on the housing during daylight and bright conditions, the anti-glare hood
provides a better view of the camera LCD screen. First, it blocks the light of the sun from
reflecting on the back door of the housing around the area of the LCD screen. Second, it shades
the area of the LCD screen, thereby making it appear brighter and clearer.
In order to install the anti-glare hood on the housing, first secure the anti-glare hood to the
housing by tying its secure string to the hinge found at the left side of the housing, where the
Fiber Optic Cable Plate secure string is attached to. Install the anti-glare hood over the anti-glare
hood rails at the back of the housing. First install the anti-glare hood over the top rail and then
gently and carefully stretch it downwards to install it on the bottom rail.
The anti-glare hood can be removed from the housing when photographing in low light
conditions, such as during night dives, wreck dives and cave dives.
