Exposure control on the D- 2000 is usually TTL (through the lens). Your own camera determines the correct exposure and instructs the D- 2000 to add the right amount of light to properly expose your subject. The advantage of using the cameras own light meter is that the light meters are now very advanced, so result are usually excellent and that the light meter will be pointing directly at your subject (the strobe often isn't for very good reasons). Any changes you make to your camera settings that would influence the flash, such as increasing or decreasing the ISO, will automatically be made to the strobe. So it is hassle free and much more reliable than an auto strobe.
That said, TTL isn't perfect and some subjects can confuse it. A good example is a diver in a dark suit. The meter will overreact to the suit and cause the strobe to overexpose. So the Inon D- 2000 has a compensation feature that allows you to slightly under or overexpose your subject. You can also control your gun manually, choosing from twelve power settings. This provides very finely controlled exposures as each setting adds or subtracts a half stop.
The D- 2000 is equipped with a modelling light. This lets you check the colour of subjects that are close to the camera and is a nice feature at night or in wrecks and caves. You can choose whether to lock the light on or have it activate for just a few seconds at the push of a button.
The Inon D-2000 connects to your housing using a reliable fibre optic wet lead. It isn't necessary to have a through housing connection. Because the cameras own flash is used to control the D- 2000, it has to fire. This would cause cross lighting and backscatter in many situations. So it is important that light from it does not penetrate into the water. Inon's very neat solution is to provide reusable filters that cover your built in flash and convert the white light to infra red. Infra red won't travel through water for any distance, so any potential problems are solved. Inon offer several wet lead options for twinning up the D- 2000 for dual strobe photography.
Ultra compact, the Inon D- 2000 is easy to travel with, weighing only 525 grams without batteries. Inon strobes have proven themselves to be user friendly, rugged and dependable.
Inon D-2000s
The Inon D- 2000s offers a near identical specification to the D-2000.The only difference is that the Inon D-2000s does not have a modelling light built in.
INON D2000 Flash for TTL Simplicity with Digital Compacts
Off camera Flash/strobes let you light larger areas, use creative lighting angles and eliminate backscatter. The Inon D2000 brings together all of the key features needed to make your strobe photography simple yet versatile. It is based upon the Z220 and D240 strobes that are used by leading underwater photographers including "The Underwater Photographer" author, "Sport Diver Magazine" columnist and legendary teacher, Martin
Edge, Tom Peschak, the marine biologist whose work graces "BBC Wildlife Magazine" and author of the books "Currents of Contrast" and "South
Africa's Great White Shark" and John Collins, the man behind the hardback "Cool Waters. Emerald Seas".
The D-2000 was created for digital compact users, but offers a near identical specification to the D- 240 which is aimed at D- SLR users. The twin flash tubes provide 100 degree coverage to suit popular wide angle lenses, including the Inon 105AD and UWL100 lenses. You can increase the angle and soften the light by using Inon diffusers. These fit easily and securely to the front of your Inon D-2000 with a screw. You can choose white diffusers in strengths of - 0.5 stops to - 3 stops. Canon owners may prefer blue diffusers which help to balance the colour of the Inon D-2000 with the cast created by some Canon's electronic underwater filter.
The guide number is 20, so you've got lots of power available. On full power recycling is around two seconds, so the Inon D- 2000 is usually ready to fire again before the camera is. It's rare to need full power, so usually the recycling is near instantaneous. The Inon D-2000 runs off just four AA batteries. These are easily removed for security inspections. The D- 2000 has a transparent battery cap and the silicone O ring used to seal it is easily visible through the cap. This helps ensure that you can see the O ring is properly seated before diving.
