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 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.

Basically a digital camera is a deice use to capture pictures without the use of films. Unlike the conventional camera, the digital camera does not rely on mechanical and chemical processes. It has a built in computer and records the images it captures in an electronic form. Having and operating one does not even require the use of electricity.

Since the images that a digital camera captures is in electronic form, it is a language recognized by computers. This language is called pixels, tiny colored dots represented by ones and zeros that make up the picture that you just took. Just like any conventional cameras, a digital camera is furnished with a series of lenses that focus the light and creates the image that you want to capture. The difference here is then; a conventional camera focuses its light on a film while a digital camera focuses the light into a semiconductor device that electronically records the light. Remember the built in computer, it comes in here and breaks this information to digital data resulting to all the features of the digital camera.

Another feature of the digital camera is that it has a sensor that converts light into electrical charges. A charge coupled device or CCD is an image sensor that is found in a digital camera. While other low-end digital camera use complementary metal oxide semiconductor or CMOS as an image device, it can still become better and more famous in the future but most engineers are do not believe that it can replace the CCD for higher-end digital cameras.

A collection of tiny diodes, the CCD gathers electrons when they are struck by photons or the light particles. Each diode or photosite is sensitive to light, meaning that the brighter the light, the number of the electrons gathering will be larger

The price of a digital camera nowadays have been depreciating, one of the main reasons of this is because of the introduction of CMOS image sensors, this is because CMOS sensors are less expensive and are easier to manufacture than CCD sensors. A CCD and CMOS sensor works the same way at first, by converting the light electrical charges into photosites. Simply putting it, is to think that a digital camera works in such a way as thinking that the millions of tiny solar cells, each of which forms a part of the whole image. Both CCD and CMOS do this task using different methods.

When shopping for the best digital camera, take note of these key features.

Image quality. Check the resolution of the camera. The higher the resolution, the more thou will be able to enlarge your picture without the grainy or the out-of-focus effect that we all want to avoid.

Lens. Choose a digital camera with better digital zoom. The digital zoom of the camera will enable you take the pixels from the image sensor and incorporate them to make an image.
Power. Always opt for rechargeable batteries, they can always come in handy, plus you don’t waste as much money on the disposable ones.

Options. So you can brag to your friends how good a photographer or artist you are. Or choose the one that gives options that best cater to your lifestyle, so you won’t ever whine how you never get the right pictures.

Memory. If you’re a photo freak, be sure that you have enough memory in your camera to take all the wacky, freaky, funny and just about any photo you can. Think 512MB if you’re a photo junkie and takes pictures of just about anything.

Computer Interface. Always make sure that it is compatible with your PC, laptop, palmtop or whatever your local picture printer software is, you don’t want to go running around the whole state or the country looking for a computer that’s compatible with your digital camera, wont you?!

Physical. If you are going to be bringing it everywhere, choose a handy and portable digital camera. This way, it won’t always feel as heavy and bulky as those cameras that you see professional photographers are always dragging on their neck. Don’t they ever get tired of that?!

These are just the basic things you have to look for in a digital camera when you buy one. A digital camera is so great that it is quickly replacing all conventional cameras in the market, with all its technology and portability, truly the digital camera is the future of cameras.

Digital cameras come in many sizes, colors, brands, zooms, resolutions, playbacks, etc. There are so many features and qualities that are being placed in the devices that buyers especially first timers become overwhelmed and dizzy with these outstanding arrays of gadgets. This is even without including the various advertisements and different ratings that are used to promote these products.

So what are the things to look for if you want to buy digital camera? To be able to answer these, there are 2 sets of information you have to know before you can decide. The first type of information is defining what YOU need and want in a digital camera. To do this, you can ask yourself the following questions:

- What do you want to take with your digital camera? Before you buy digital camera, it is important to determine what kind of pictures you want to take with it. If you are a digital photography enthusiast, any digital camera will not just do. You have to look for features that can support the zooming you need, the resolution, etc.

- How much is your budget? This is a very important question any person who intends to buy digital camera should ask. Because no matter what your needs and wants are for the device, your financial resource will play a huge part in dictating the type of digital camera you will buy.

- What are you resources? When you buy digital camera, sometimes the spending does not end there. You also have to consider the capacity and the power of the computer and the printer you will be hooking your camera with for your editing and printing needs. Editing software are already included when you buy digital camera but other devices aren’t. Aside from a printer, ink and paper for printing, you might also need additional memory cards for your camera and a more powerful computer to support image editing and image storage and retrieval.

After answering these 3 questions, the second set of information you need to know before you buy digital camera are the features that you need in the device. These are:

- Resolution. Before you buy digital camera, check first its capacity to produce high quality photo images. The number of pixels indicated determines resolution. The more number of pixels, the higher the resolution which can make photos to be enlarged without losing image quality.

- Built-in memory. Digital cameras need memory cards for picture storage. When you buy digital camera, make sure that the gadget that you buy does not only have a “built-in” memory but should also have a card slot for external and additional memory. This allows you to change full memory cards conveniently while shooting your pictures.

- Look and feel. It is essential for you to feel comfortable holding your digital camera while shooting. So, before you buy digital camera, it good to test and check if you are comfortable holding it and using it. Consider where the buttons are located and how they are spaced out and see also if you feel comfortable using the viewfinder.

- Battery life. Digital cameras use up batteries fast and batteries are expensive. Before you buy digital camera, consider if the camera’s batteries are rechargeable. This way you can recharge them. Take also into consideration an AC adapter when you buy digital camera. You can attach this to the camera when you are viewing your pictures or uploading them

- LCD. The LCD is a special consideration you have to look into when you buy a digital camera. This is a small screen located at the back of a digital camera that allows you to preview the pictures you took. This has to be considered when you buy digital camera because it uses up a lot of battery power.

- Special features. Special features that will suit your needs should be thought about, too before you buy digital camera. If you want your camera to have good zooming, you can opt for those with optical zoom lenses. A diopter adjustment on the digital camera’s viewfinder will also be beneficial to those who regularly wear glasses and wish to buy digital camera. Other features such as remote control, tripods, etc. can also be considered when you buy a digital camera.

With these information, you can now figure out what you really need and want before you buy digital camera. If you want to see ratings and rankings of these devices based on price, resolution or other features, check out various websites that have these in the Internet.
