General Tips

1.Due to the power required to operate the camera, flash, and LCD screen it is a good idea to start each dive with a fresh set of batteries.

2.Some cameras reset their flash to AUTO when the camera is turned on. If you prefer another setting be sure to select it.

3.As soon as you enter the water, take a moment and check the housing to see that it is properly sealed.

4.Next, check to see if there are any bubbles on the face of the lens port. If there are, take your finger and remove them. If there are bubbles on the lens port they can produce soft focus spots in your photographs.

5.If you use the housing Zoom control, make sure to move it back to the center position. If the housing Zoom control is pushing the camera zoom lever to either side the camera will not function.

Photo Tips Cont.

5.Since opinions vary on what is the correct exposure you may want to adjust your camera for what you like exposure wise. Many cameras allow you to adjust both available light and flash exposure with an EV control.

6.Many photographers transfer their images to the computer where they can fine tune the appearance of the image. Many of the image manipulation programs make you think you can magically correct any image taken and make a good picture. One thing to remember when using image manipulation programs, if the image is overexposed much of the color is missing. If the color is missing you cannot adjust it. If images are underexposed some color and detail may be there, it is just dark and you can adjust it to some degree. So if you error in exposure it is better to have the image slightly underexposed than over exposed.

Photo Tips

1.The number one rule in underwater photography is eliminate as much water between camera and subject as possible. Get as close as you can to the subject, then use the zoom. If you are using flash, subjects beyond 6 feet (1.8m)will not have much color.

2.Digital cameras have a slight lag time between when you press the shutter release button and the camera actually takes the picture. Hold the camera steady a second or two after pressing the shutter release button.

3.Do not shoot down on subjects as they will quite often blend into the background and be difficult to see in the photograph. Shoot subjects straight on or shoot up at a slight angle using the blue water as a contrasting background.

4.Underwater flash is used to restore the warmer colors filtered out by the water as well as to illuminate the subject. When photographing underwater, set the camera to use flash on every shot. If the camera's flash is set to AUTO and the sun is behind your subject, the camera may see enough light that it does not fire the flash. With the sun behind the subject the subject is shaded (dark) and needs flash for a good exposure.

A630, A640 specifications

The Ikelite A640 and A630 underwater housings are specifically designed to enhance and protect Canon's popular PowerShot A-series cameras. These housings are built to withstand the unique challenges posed by underwater environments, providing photographers with a robust solution for capturing stunning images beneath the waves.

One of the standout features of the Ikelite A640 and A630 housings is their depth rating. Both models boast a remarkable depth rating of up to 200 feet (60 meters), making them suitable for a wide variety of underwater activities, from snorkeling to deep-sea diving. The housings are crafted from durable polycarbonate material, ensuring their longevity while also allowing divers to clearly see the camera's controls.

The design of the Ikelite A640 and A630 housings incorporates large, easy-to-use controls. These controls are specifically designed to mimic the layout of the camera’s buttons, enabling users to effortlessly operate the camera while wearing diving gloves. This ergonomic design ensures that photographers can concentrate on capturing images rather than fumbling with complex settings.

An appealing aspect of the Ikelite A640 and A630 is the inclusion of an integrated TTL (Through The Lens) exposure system. This technology allows for automatic flash exposure, ensuring that users can achieve balanced lighting in their images without the need for complicated manual adjustments. This feature is particularly advantageous in underwater photography, where lighting conditions can be unpredictable.

Furthermore, the housings are equipped with a built-in flash diffuser that softens the flash output, helping to reduce backscatter, which can often mar underwater photographs. The capacity to attach additional lighting systems is also a remarkable characteristic. Both housings feature an accessory port for attaching external strobes, allowing for greater flexibility and creativity in lighting setups.

The Ikelite A640 and A630 provide a clear view of the camera’s LCD screen through a large viewing window, enabling users to frame their shots accurately. This is particularly crucial in underwater photography, where visibility can be compromised by water quality and lighting conditions.

In summary, the Ikelite A640 and A630 underwater housings represent a fusion of durability, user-friendliness, and advanced technology, making them ideal companions for Canon PowerShot A-series camera users who wish to explore and capture the beauty of underwater worlds. Their reliable performance and thoughtful design features make them a must-have for enthusiasts and professionals alike.
