DIGITAL CAMERA: THE FUTURE OF CAMERAS

 

Essentially, a digital camera functions by capturing pictures without the need for 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 electronic form. Having and operating one does not even require the use of electricity.

A digital camera captures images in electronic form, which computers recognize as a specific language. Computers recognize this language as pixels, which are tiny colored dots represented by ones and zeros, forming the picture you just captured. A series of lenses equip a digital camera, just like any conventional camera, to focus light and create the desired image. The distinction lies in the fact that a conventional camera directs its light onto a film, whereas a digital camera directs its light onto a semiconductor device, which then electronically records the light. Remember, the built-in computer transforms this information into digital data, thereby enabling 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 digital camera uses a charge-coupled device, or CCD, as its image sensor. While other low-end digital cameras use complementary metal oxide semiconductor, or CMOS, as an image device, this technology has the potential to improve and gain popularity in the future. However, most engineers do not believe it can replace the CCD in higher-end digital cameras.

When photons or light particles strike the CCD, a collection of tiny diodes, they gather electrons. Each diode or photosite is sensitive to light, meaning that the brighter the light, the number of electrons gathering will be larger.

The price of a digital camera has been declining in recent times, primarily due to the introduction of CMOS image sensors, which are less expensive and 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 put, a digital camera functions similarly to millions of tiny solar cells, each contributing to the overall image. Both CCD and CMOS technologies accomplish this task using distinct methods.

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

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

Lens. Select a digital camera that offers a superior digital zoom. The camera's digital zoom will allow you to capture the pixels from the image sensor and incorporate them into 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. This allows you to showcase your skills as a photographer or artist to your friends. Alternatively, select a photographer who offers options tailored to your lifestyle, ensuring you never have to wonder why you never manage to capture the perfect shot.

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 photos you can. Think 512MB if you’re a photo junkie and take pictures of just about anything. 

Computer Interface. Ensure that your computer interface is compatible with your PC, laptop, palmtop, or your local picture printer software. You don't want to waste time searching across the entire state or country for a computer that is compatible with your digital camera.

Physical. If you are going to be bringing it everywhere, choose a handy and portable digital camera. This way, it won't feel as heavy and bulky as the cameras that professional photographers constantly carry around. Don’t they ever get tired of that?!

These are the basic features you should look for in a digital camera before purchasing one. A digital camera is so great that it is quickly replacing all conventional cameras on the market. With all its technology and portability, it is truly the future of cameras.
