Using your Safari Li-on as a ringflash
If you have bought a Li-on ringflash kit, or have bought the optional ringflash head to go with your Li-on
kit then you have the best ringflash kit on the market!
The ringflash head can be used either on its own, as a pure ringflash, on its own as a fill flash or it can be
used in conjunction with a standard flash head.
Used on its own as a ringflash, you may wish to plug it into socket B, which will give you a minimum of
12.5 Ws and a maximum of 200 Ws. That’s usually plenty of power for a ringflash, but if more power is
needed you can of course plug it into socket A, which will provide a minimum of 25 Ws and a maximum
of 400 Ws – or, if you press the A+B button, a minimum of 38 Ws and a maximum of 600 Ws.
To get the full ‘ringflash effect’ of gentle outwardly radiating shadows, you need to be as close as
practicable to your subject, although of course if you’re very close you may see perspective distortion.
Exposure: With a flash head mounted on a stand, the distance to subject is constant regardless of the
distance from camera to subject, allowing the photographer to change position without having to adjust
the exposure, but with the ringflash mounted to the camera any change to distance will also affect
exposure. Because of this you may wish to use a wideangle zoom, something like a 17-55mm on a
cropped-frame camera or a 24-70mm on a full frame camera, and use the zoom to create different
effects without changing the distance, instead of moving closer to or further from your subject.
Ringflash diffuser: If you fit the
optional ringflash diffuser
the light will be softer and the shadows will be
less pronounced. Fitting the diffuser will also allow you to easily fit lighting gels between the flash head
and the diffuser, to colour part or all of the foreground of a scene or, if a neutral density gel is used, to
create less light at the top, bottom or one side of the image.

However, if you fit the diffuser you must
ensure that the camera lens protrudes beyond the diffuser, otherwise there is a real risk of lens flare
from light entering the lens, transmitted through the diffuser. If it is impossible to fit it so that the lens
protrudes beyond the ringflash, for example if the lens is a ‘nifty fifty’ or similar, you
must
fit a lenshood
to prevent flare.
Redeye: Redeye is caused by light on axis with the camera lens, striking the eye and reflecting straight
back. It isn’t created by a ringflash but, because the ringflash is directly on axis with the camera lens, it
can sometimes be a problem. Using your ringflash in good lighting conditions will normally prevent
Mounting the ringflash: The ringflash head can be used with all
camera/lens combinations as long as the lens has a diameter of no
more than 98mm. Mount it and adjust the brackets so that it’s
comfortable and allows plenty of room to operate the camera
controls. Used without the diffuser, it doesn’t matter whether the
front of the lens is behind or in front of the flash tube.
