New technology is omnipresent. The ongoing technology revolution is rapidly changing the cultural and social landscape of the world. Thirty years ago, choices were simpler. Take the example of cameras .35 mm cameras came in three basic models, specialized cameras like the Nikon "F" & F2, The Canon F1, and the Pentax LX, amateur level cameras like the Pentax Spotmatic, the Nikkormat "FT" series, and the Minolta SRT models, and finally the compact cameras that are called Point & Shoots today.

During the last thirty years camera technology has changed dramatically and digital cameras [digi cams] have essentially replaced traditional 35mm film cameras in popularity. Features like auto exposure, auto focus, auto flash, and program modes have made taking pictures simpler and provided photographers with options that people ever dreamed were possible.

One of the best things about digital photography is that you can see your picture right away. With just a few clicks of the mouse you can download, systematize, alter, and share all of your digital photos. Digital photography is used not only to take amusing pictures, but also by people in a lot of important professions: scientists, police, health care, lawyers, educators, and many others. Though this sounds easy, it has taken more than 150 years of dynamic technological change to bring the digital camera to its current status. It was only several years ago that Casio made the "QV-10" digital camera public. It offered a maximum resolution of only 320 x 240 pixels, had internal memory only (no memory cards) and did not have a built-in flash. Image quality was quite bad, but it did offer one of the first color LCD screens on a consumer digital camera at the time. But the price was a whopping $500.00! Still, a number of these units were sold. Kodak also offered a couple of models in the $1,000.00 range, as Sony introduced one of the first floppy disk "Mavica" camera , and Epson came out with the first "PhotoPC" for under $500.00. A year or so later, the first 1 to 1.3 mega pixel models were being introduced at the same price point, and this time, Olympus began to lead in terms of image quality and camera features. Sony was not far behind, with Kodak and Nikon picking speed. Casio and Epson seemed to have trailed during this early stage, keeping models few, though later on each would begin to crank out higher spec cameras.

Digital Cameras lets us see things we have never seen before. One of the biggest digital cameras, the Hubble Telescope has sent digital images from deep space since 1990. One image even showed a planet outside our solar system! But it’s not just the big stuff that digital cameras help us see. It also lets us see the minutest things like microscopic particles.
Explore the various options about how you could use digital photography. Would it be to take pictures of your baby once a week to chart its growth? Or would it be to start a science project? Digital photography lets you experience photos like never before.

When buying a digital camera, a few things should be kept in mind- Match mega pixels in accordance with use, look for rechargeable batteries and charger, get at least 3x optical zoom, consider investing in a memory card and try the camera before you buy it.

The best way to buy digital cameras is from online stores rather than the traditional mortar and brick shops. Here you will get a wide range of cameras for the lowest prices from the best stores around the world. Sites such as Mobile Phone Shop, Amazon.com, Markways.com, Bestbuy.com, etc offer great value for money.

There are very few people in this world who posses the kind of social graces intrinsic to the characters in an Austen novel. Some would argue the children of the “information revolution” lack social propriety altogether. Despite the rumours that etiquette is dead, many of us do manage to exercise a little common courtesy toward our fellow man. After all etiquette exists simply to make the whole society caper a little less confrontational. The introduction of wireless communication has taken social interaction to an unprecedented level. Mobile technology allows people to communicate regardless of time or location, giving rise to a raft of contemporary etiquette concerns. Foremost among these concerns is consideration for the sensibilities of those in our physical presence when we take a call. Is it impolite, for example, to conduct a phone conversation whilst engaged in a carnal act? The contemporary socialite must also extend courtesy to the absent caller. Is it offensive to conduct a telephone conversation whilst using the toilet? This article offers guidance to the bewildered and brutish.

1. It is a truth universally acknowledged that cell phones must be switched off in the theatre. There is absolutely no excuse. Offenders shall be tarred and feathered. Obviously, this also applies to the cinema, the symphony and spoken word and performance art. Rock concerts and hip-hop shows are generally considered exempt, however, a punter with his fingers in his ears screaming “Huh? huh? huh?” into his cell is a frightful sight.

2. When piloting an automobile, use a hands-free device or resist answering incoming calls. Not only is it dangerous to talk and drive, it is illegal in many countries. Care should be taken not to incite road rage in other motorists. Furthermore, chatting vacuously on your cell while mounting the footpath will pique pedestrians.

3. Conducting loud cell phone conversations on public transport should be avoided at all costs. To believe that other commuters ought to be interested in your conversation is narcissistic at best, to subject travelers to your confabulation is an indulgence. Moreover, as one clever blogger puts it, there is a special circle of Hell reserved for people who, upon buying a new phone, cycle through every available tone on the bus or train on the way home.

4. When in the company of others, neither take nor make telephone calls. Nothing is more irksome than being spurned by a friend whose frequent cell phone conversations take precedence over live tete-a-tete. Answering an incoming call in an interview or business meeting is a faux-pas that is to be avoided at all costs.

To observe basic cell phone etiquette is neither difficult nor inconvenient. Technology such as cell phones create many possibilities for the advancement of society; society is founded upon mutual regard for one another. Always refer to the fundamental principle of good manners: treat others as you yourself wish to be treated. As for holding a cell phone conversation on the toilet...ignorance is bliss.
