Everything Digital Cameras

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 you’re 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 camera’s 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 don’t disturb the camera’s operation. (Silica gel will keep the moisture from forming inside your camera case.)

Most underwater digital cameras come with optional lenses. Don’t 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 you’ve 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.

Check out Sony, Nikon and Canon’s website for available underwater cases for your digital cameras.

Major manufacturers such as HP, Kodak, Samsung and Fuji offer cheap digital cameras too. Cheap digital cameras generally have lesser advanced features such as multiple file resolution settings, optical zoom, optional image file type settings, advanced automatic exposure meters, large capacity memory cards, replaceable lenses and waterproofing. Most of the cheap Digital cameras are of point and shoot type.

Image quality is related to Megapixel rating directly and the handling of white balance by the camera. If you want to post pictures on a web site, email pictures or store them on hard drives, cheap digital cameras with a 1.3 Megapixel rating are more than satisfactory. If you want to have images of portrait quality, then you have to look for cameras with 3 mega pixels or higher ratings.

Due to the Megapixel rating, many cameras are expensive. The higher the rating of the mega pixels, the larger the photographs. However, cheap digital cameras will not come with a lot of mega pixels but still may not be necessary at all times. You don’t require a lot of memory if you don’t need very large pictures. Most cheap digital cameras will print eight by ten inches and this is what many people may need.

Still, most people often get discouraged from buying a used digital camera as they feel that they can get great pictures by getting the most expensive camera available. There are many cheap digital cameras available for sale and you may not require all of the fancy features and thus can save money.
