INON Underwater Strobe And Video Arm Systems

Ocean Optics's underwater photography instructor Mark Koekemoer experimenting with "bunny ears" lighting on the wreck of the Thistlegorm off Egypt. He's using a Panasonic Lumix GF2 in an INON X2 housing withINON Z-240 strobes. INON float arms both stabilize his camera system foreasier shooting and allow complete adjustment of lighting angles. Bunnyears is a technique used to eliminate backscatter and ensure even lighting.

Underwater strobe arms are an essential part of helping you to properly light your underwater photographs and video sequences. The difference between using a well designed underwater flash arm and using one that is poorly thought through and constructed is often the difference between an excellent underwater photograph or video footage and a ruined image. It's only through proper placement of your underwater camera flash or underwater video light that you can expect to evenly light your subject and avoid backscatter. During our INON UK Level One underwater photography courses for beginners we show why lighting underwater goes wrong so easily and how to prevent lighting disasters. Future courses will explore advanced lighting techniques used for creative underwater photography, which will include using flash arms for on camera illumination, use of multiple strobes as well as off camera remote lighting skills.

INON strobe arms for underwater cameras are fully articulated for precision lighting control. They also have mounting points for INON wet lens and UR Pro filter holders and enable you to perfectly adjust the buoyancy and trim of your underwater camera to improve its handling.

INON arms satisfy competing needs. An underwater flash arm must be easily adjustable to let the photographer quickly raise or lower the underwater flash or underwater video light as the subject gets nearer or further away. Quick adjustment is also needed for angling the light for creative side, top or underlighting. However the arm also needs to hold the underwater strobe or underwater video light firmly in position -even if the photographer is facing into ripping current and strung out on a reef hook off Palau. INON strobe arms use a clamp to connect arms and arm fittings which uses an embedded O ring to provide friction. Once the clamp is correctly tensioned for your strobe or video light, you won't need to touch the clamp again to make adjustments to your lighting angles. The clamp and O ring design lets you smoothly move your light into the best position, pretty much regardless of how contorted that position needs to be.

INON strobe arm sections come in various lengths to let you customise your lighting arm to your specific needs - even from dive to dive - to handle different subjects and conditions. For example for distance shooting, typical of fish photography or using wide- angle lenses, you'll need to keep a single strobe or video light high above your housing to prevent backscatter. INON underwater flash arms let you do this. Simpler bendy arms, often packaged with strobe outfits, usually have increasing problems supporting your light or preventing it drifting out of line in currents as the arm is made longer. This is why cheap arms are also often quite short. For close up and macro underwater photography you might need to bring your gun right in beside or over your lens to properly light your subject. Cheap arms often resist being placed in this position - they simply can't bend enough. INON arms let you easily place an underwater strobe in this position because the clamp design lets you bend, swivel and hinge the arm into the required position. For this type of photography an underwater photographer might choose a short INON arm to keep his system ultra compact.

The INON underwater flash and underwater video light arm and accessory range provide the underwater stills and videographer with a truly customisable, upgradable and user friendly precision lighting control system.  A choice of adapters lets you mix and match your INON arms with almost all other manufacturers housings, trays, strobes or lights. The INON underwater strobe and video light arm, selected properly to meet your personal needs, is the vital link between your expensive camera, lenses, housing and strobe or video light and the subject you've invested time and money to encounter.

Steve and Mark, regular writers and speakers on underwater photography techniques, will be pleased to talk through the best options for selecting an INON underwater strobe or video arm for your needs.

INON Frame Arms
 

---

INON frame arms are made from anodised aluminium.
Apart from the smallest arm, all use a lattice design.
This reduces the weight of each arm section for
travelling. It also minimises drag by allowing the water
to easily flow through.

Arm XS - 75mm long

Arm SS - 120mm long arm

Arm S - 150mm long arm

Arm M - 200mm long arm

Arm L -  320mm long arm
(accepts two Arm Float S)

Arm Float S

The INON Arm Float S clips to most INON frame arms to provide 70 g of positive buoyancy. Two can be mounted onto to the INON Frame Arm L. More buoyancy can
