Digital Camera Technology:
The Future Of Photograhy

At the heart of digital camera technology is the ability to capture pictures without the use of film. 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, other than batteries.

Since the images that a digital camera captures are in electronic form, their language is 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 camera, a digital camera is furnished with a lens that focuses the light and creates the image that you want to capture. The difference is that a conventional camera focuses its light on film while a digital camera focuses the light into a semiconductor device that electronically records the image. Remember, the built in computer.  It comes into play here and converts this information to digital data.

Another feature of the digital camera is that it has a sensor that converts light into electrical charges. A Charge Coupled Device (CCD) is an image sensor that is found in a digital camera.  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 greater the number of electrons gathered.

One of the main reasons that digital camera prices have fallen is the introduction of CMOS image sensors.  CMOS sensors are less expensive and are easier to manufacture than CCD sensors.  CCD and CMOS sensors work much 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 megapixel resolution of the camera. The higher the resolution, the more you will be able to enlarge your picture without the grainy or the out-of-focus effect that we all want to avoid.

Lens Quality. Choose a digital camera with optical zoom.   Digital zoom is found in less expensive cameras, but does not produce the image quality of optical zoom.

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.   Do you want to be able to capture an occasional movie?  Do you want a self-timer?  Do you care about the strength of the built in flash unit for taking indoor photos?  Think before you buy.

Memory Capacity.  If you’re a photo freak, be sure that you have enough memory in your camera to take all photos you want to. Think 512MB if you’re a photo junkie and takes pictures of just about anything. You will probably want at least one, and perhaps several additional memory cards.

Computer Interface.   Most digital cameras have a built-in USB port so you can easily transfer your photos to your computer or digital photo printer.  Make sure the model you buy has this, if you intend to store or print your photos yourself. 

Physical Features. 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 some of the basic things you need to look for in a digital camera when you buy one. Digital cameras are quickly replacing conventional cameras in popularity - the digital camera is the future of photography.
