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.

Factors of the communication are, in the information theory of the engineer and mathematician Claude And Shannon and the sociologist Warren Weaver, (mathematical The Theory of Communication, Urban: The University of Illinois Press, 1949) the six elements that take part in the transmission of a message or information. They are: source, transmitter, signal, noises, receiver and adressee. This scheme soon was extended with more elements: emitter, code, message, channel, redundancy, emitted signal, received signal, situation and context. Shannon was in charge of the cuatificables aspects of the process, whereas Warren Weaver expanded east scheme when indicating that the communication problems could be analyzed in three levels: technician, semantic (referred to the meaning and interpretation of the message) and pragmatic (on the consequences of the communication in the behavior of the people.

  Later, Californian investigators of the High Wood School adopted a very critical position with respect to this model, who considered was not able to include the universal complex of the human communication, a process filled with interactions. Watzlawick, Jackson and Beavin defined in 1967 five axioms of the human communication, of which we emphasized:

1) It is impossible not to communicate. In the human interaction, all conduct has the value of a message. As noconducta does not exist, we are always communicating.
2) All communication has a content level (what we say) and a relational level (to whom and how we say it). We not only transmitted data, also we establish a relation with our interlocutor.
3) the people use so much the communication digital (linguistic symbols and/or written) like the analogical one (nonverbal language).
The factors or elements that take part in the communication are, more or less, the following ones:

The source is the information or content in gross without codifying for being transmitted in the message. For example, the temperatures of a weather message.
The emitter is the element that takes and elaborates the source according to a code to transmit a message elaborated by means of the same one. The man of the time, for example.
The code is the set of signs and rules of combination of such that serves to transmit a information or source according to a comprehensible or decodable symbolic system for the emitter and the receiver. For example, the system of measurement of temperatures that we adopt in a weather message: centigrade, Réaumur scale, Fahrenheit… or the language that are used in a weather message: the Spanish, the English…
The message is the information of the source already elaborated and formed by means of the code: the weather message as it leaves emitted.
The emitted signal is the intensity of the transmission once leaves the emitter, always more intense and less modified or distorted than the received signal.  

The channel is the average physicist through as the message is transmitted: nervous system, air, receive, water…

The noise is all element, psychic physicist or, whom a loss or distortion in the content causes or forms of the message: opacity of the channel, weakness of the signal, distances, fatigue of the emitter, bad understanding or possession of the code, ambiguity, deafness, distraction, madness, prejudices etc…
The redundancy is the recurrent repetition of information that is made in the message in order that the alterations, distortions and losses of information that causes the noise do not cause a flight of excellent information.
The context is the knowledge of a series of lingüísticas circumstances (previous messages to the message, necessary knowledge of presuppositions and data for the intelección of the message) that is to have the message to be able to be understood exactly.

The situation is the physical, temporary and space frame, of extralinguistic nature, in which the communicative process is developed, and that sometimes is essential to be able to interpret a message correctly.
The collector is that to that the message goes destined, but that it necessarily does not have to be the element that deciphers it.
The receiver is the one who receives and deciphers to the message codified by the emitter using the same code whereupon it was based if the transmission is ideal.

Well, we’ve been warned that this time would come - probably from the earlier eighties on. Yes, computers have finally taken over and if you doubt it, we’re here to convince you - but not because we want to or because we can. We want to convince you that if you don’t take the necessary steps to control that reign, you’re going to be left behind further than you could have ever imagined.

Computers are everywhere. Take a moment to try and think of a place a business where you didn’t see a computer in use. From the small local corner store to the largest hospital, computers are in every gas station, grocery store, bank, restaurant, beauty shop, and doctor’s office around. From a consumer’s point of view - you may not think that’s much to worry about. But along with computers, we’ve also been infiltrated with a little thing called "self-service." Today, there are more self-serviced resources than ever and in an effort to synchronize them with headquarter databases, they’re provided via your inescapable computer.

Here are some examples. Banking is self-serviced through the desktop-clad ATM machine. Gas stations are self-serviced through a menu-clad touch screen kiosk. Most cash registers are Windows XP or Vista machines that send purchase details back to headquarters via the Internet (or a small Intranet). Having your weight, blood pressure, and heart rate measured and recorded is now a digitized process. Even ordering a pizza is now a simple matter of dialing from a wireless cell phone and making a few selections from series of pre-programmed menus!

The important thing to realize here is that this phenomenon isn’t a new convenience - it’s a new requirement. And if you haven’t jumped onto the binary wagon, you’re going to face a few problems. For just as this new lifestyle was once predicted, we’re going to predict that "the old ways" will slowly disappear.

We’re going to predict that all paper-based transactions (checks, money orders, etc.) and documentation (think of the old filing cabinet system) will disappear. We’re going to predict that chips will replace everything that was once transported from one location to another through the trusty post office. And we’re going to predict that homes will become less cluttered with stacks of paper and that our natural resources will flourish as a result of it.

This all sounds fine and dandy of course, but if you’re not computer savvy, you’re going to feel a little lost once the choice has past and the revolution is 100% complete. Fortunately, computer systems are designed in a way that even a child can manipulate them. In fact, if you can remember that most systems are designed along the line of menus and the selections of a few options on these menus, you’ll do just fine no matter how many buttons there are to push.

For example, when you’re faced with an electronic system, look for a main menu. Most main menus display themselves as soon as a device is turned on, so chances are that if you’re standing before a device that shows a bunch of choices to do something, you’re looking at a main menu. The buttons on these main menus of course take you to additional menus, which in turn give you even more choices to make. And all of those choices will eventually bring you to the service that you need. One very important choice you’ll want to keep your eye on is the option to return to the main menu. This way, you can return to the beginning of a system and start over in case you get lost among the way.

Another important choice that you want to keep your eye on is the choice to get help! This option may not be available on every device that you encounter, but when it is available, be sure to use it.

There’s just no way around it. Computers and computerized systems are here to stay. There’s no need to fear them - but you surely can’t avoid them. Just remember the menu system and you’ll soon discover that you can approach and use these things as if you designed them yourself.
