Underwater Cameras:Discover A Whole New World
It is a known fact that over seventy-five percent of our world is covered in water, this world has just as many interesting things to take pictures of and is always changing with every ripple and wave. Underwater cameras are a great way to capture these scenes that are ever changing. Underwater cameras are great for deep-sea divers and the snorkeling community alike. They are also a great type of camera to take to the pool or lake to sneak a few pictures of the local wildlife in the water and around the water. No matter if you are new to using an underwater camera or picture taking in general, the water has a lot of offer and just waiting to be seen.
These types of cameras are not to be confused with a normal camera that is used every day on land. An underwater camera is specially made to be able to be completely submerged underwater and able to take the pressure surrounding it and has a waterproof casing. The underwater camera also takes the same great quality pictures on dry land in rough and rugged conditions, but it has advanced features for a water setting.
Underwater cameras come in all shapes, sizes and film format. Many digital cameras that are made for the underwater environment come with a viewfinder so you can see exactly what you are taking a picture of and what your camera sees. There are still a great line of underwater cameras that use film that needs to be developed and they work just as well as a digital camera and take the same great picture. The smaller underwater cameras are normally very good for up to two hundred feet to four hundred feet while the bigger cameras are made for deeper regions of the waters.
How do Underwater Cameras Work?
Underwater Cameras are cameras that are specially designed for underwater use or in circumstances that requires protection to prevent any water and pressure damage. There are many types of underwater cameras, depending on your budget and uses.
There are underwater cameras that are simply disposed of after use. These are the cheapest type of underwater camera available in the market. They have the capacity to take between 20 to 30 pictures, and photos can easily be developed. They are waterproof enough to be used in harsh rain and snow storms, and are usually tolerant of being fully submerged up to twenty or thirty feet.
There are also underwater cameras that are cheap reloadables. These cameras are designed with economy of price in mind. These are very similar to disposable underwater cameras, expect that the user can replace the film and use the camera multiple times. They are usually capable of greater water depths than their disposable counterparts.
New generation cameras have resolutions in the 3-4 megapixel range and can take excellent quality pictures underwater.
These cameras offer options for every level of diver and snorkeler. For the experienced diver/photographer who wants more control over the camera functions. The Advanced-Dive control system allows users to manipulate resolution, light sensitivity (EV), exposure modes and much more while underwaterwhile the Easy-Dive control system is the perfect choice for divers seeking a simple underwater photo system that produces breathtaking results.
Underwater cameras are designed for one-Button-Operation and can be set to Land or Sea modes plus modes that take into account the unique aspects of underwater photography. Cameras also feature three dedicated underwater external flash modes, allowing for more exposure control when using an external flash. For perfectly lit photos in any situation, users can toggle among Macro Flash, Portrait Flash and Far Flash modes, which adjust exposure based on camera-to-subject distance.
While an on-camera flash helps illuminate objects below the surface, cameras are also compatible with external flash units, which ignite the vivid colors of the underwater environment and allows users to illuminate objects from different angles. Because the external flash is a unit activated via the on-camera flash, no sync cord is necessary. Set the camera to “External Flash,” and it automatically de-activates the digital pre-flash.
To compensate for low-light conditions that naturally occur as divers travel below the water’s surface, cameras can adjust the shutter speed and aperture automatically to compensate for difficult light conditions, ensuring vivid images without worry of underexposure.
Photos can be composed via a large color LCD monitor on the back of the camera; or users can frame subjects through a top-mounted SportsFinder. Either way, composition is simple, even when viewing subjects through a dive mask. To help conserve power during underwater adventures, users often shut off LCD monitors while the camera is on and compose photos using large top-mounted viewfinders.
With the many technological advances of recent years, underwater photographers now no longer have to compromise on quality. Users are almost guaranteed to return to land with a stunning set of images.
UNDERWATER DIGITAL CAMERA:CAPTURING MOMENTS UNDERWATER
Memories are created just about anywhere. And when I say anywhere, I mean that memories are even created underwater so the creation of underwater digital camera.
An underwater digital camera is not just used to capture underwater memories; some professional marine photographers also use underwater digital cameras in their business. Even marine biologists and scientists use underwater digital cameras to capture marine life and thus be able to study the life and properties of the marine life. But I think it is safe to assume that you, my reader, are neither a marine scientist nor a professional photographer. Like me, you are just some photo junkie who wants to capture underwater moments and just cant figure out how without ruining your cameras.
Please listen to me when I say that even waterproof cameras cannot withstand underwater photography. To be waterproof is to resist the water in certain levels, submerging in under the water to get the perfect shot is like throwing it out of the window expecting a pick-up truck to pass by and run over it.
Now if youre really serious about using an underwater digital camera to capture those wacky and funny moments underwater, I suggest that you buy specialty cameras.
There are rarely underwater digital cameras, as cameras are electronic and cannot withstand water and water pressure. The closest electronics has ever got to producing underwater digital cameras are producing underwater casings for digital cameras. These casing will turn your conventional digital camera into an underwater digital camera.
If you are shooting with your underwater digital camera, you need to take note of a few things to help you come up with the best images underwater.
Remember that as you farther under water, light diffuses. This means that your underwater digital camera will produce images darker than those images you took while on land this is because of the light diffusion the red spectrum seems darker. To avoid this, use white balance come up with natural colors. Also, pictures taken underwater will come up larger than pictures taken on land with the same zoom effect. Be sure to check your underwater digital cameras viewfinder to check the right picture angle and size that you want.
An underwater digital camera with its built-in flash will produce marine show phenomenon. It is a phenomenon wherein your pictures come out as blurry and with white particles floating above it, to avoid this phenomenon it is advisable to use external flash for your underwater digital camera.
Before using your underwater digital camera, submerge the camera in the water first for several seconds then check if there are leaks through the case. Make sure that no grain of sand or piece of hair is stuck in between the seal to make sure that water will not permeate the case and thus wet your camera in the process. It is also advisable to put silica gel or two inside the case of your underwater digital camera as long as they dont disturb the cameras operation. (Silica gel will keep the moisture from forming inside your camera case.)
Most underwater digital cameras come with optional lenses. Dont be afraid to add these lenses to your underwater digital camera kit. Macro lenses will help you capture small things without getting too close and startling your subject.
Also, remember to always wash of salt when youve used it under salt water. If the salts are not washed off, in time they will crystallize; act as sands and cause leaks for your camera case. In cases when sands seem to get into the case, they are better washed off with streams of water.

The image that you are focussing on is displayed on a small screen on the rear of the camera there is no eye piece as such, unlike the conventional cameras the you may have seen.
A little pressure on the focus/execute button makes the camera focus and calculate exposure – a full press will cause the camera to take a picture. Most users will use this fully automatic mode.
The screen found at the back of your camera will allow you to review images taken. It makes it possible to review the shots that you have taken, and you can delete the images you do not want to keep. Use the lower toggle switch to step through the shots you have taken.
To quote the words of one professional underwater photographer, “the Nikon D70 allows access to all of the most frequently used buttons and functions. Absent is the Depth-of-Field preview button, which I feel is rather useful but some may not even know exists!”
Indeed, using the additional settings of AF-C (Continuous Auto-Focus) and Dynamic-AF area, one can shoot macro, wide-angle and even portraits by simply and quickly changing the lens. You’ll see the benefit of this sharp and precise auto focus system when it comes to chasing and capturing very fast subjects.
