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.
