1. DIGITAL CAMERA: THE FUTURE OF CAMERAS
Basically a digital camera is a deice use to capture pictures without the use of films. 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.
Since the images that a digital camera captures is in electronic form, it is a language 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 cameras, a digital camera is furnished with a series of
lenses that focus the light and creates the image that you want to capture. The difference here is then; a
conventional camera focuses its light on a film while a digital camera focuses the light into a semiconductor
device that electronically records the light. Remember the built in computer, it comes in here and breaks this
information to digital data resulting to 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
charge coupled device or CCD is an image sensor that is found in a digital camera. While other low-end
digital camera use complementary metal oxide semiconductor or CMOS as an image device, it can still
become better and more famous in the future but most engineers are do not believe that it can replace the
CCD for higher-end digital cameras.
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 number of the electrons
gathering will be larger
The price of a digital camera nowadays have been depreciating, one of the main reasons of this is because of
the introduction of CMOS image sensors, this is because CMOS sensors are less expensive and are 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 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 resolution of the camera. The higher the resolution, the more thou will be able to
enlarge your picture without the grainy or the out-of-focus effect that we all want to avoid.
Lens. Choose a digital camera with better digital zoom. The digital zoom of the camera will enable you take
the pixels from the image sensor and incorporate them to make 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.

2. Options. So you can brag to your friends how good a photographer or artist you are. Or choose the one that
gives options that best cater to your lifestyle, so you won’t ever whine how you never get the right pictures.
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 photo you can. Think 512MB if you’re a photo junkie and takes
pictures of just about anything.
Computer Interface. Always make sure that it is compatible with your PC, laptop, palmtop or whatever your
local picture printer software is, you don’t want to go running around the whole state or the country looking
for a computer that’s compatible with your digital camera, wont you?!
Physical. 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 the basic things you have to look for in a digital camera when you buy one. A digital camera
is so great that it is quickly replacing all conventional cameras in the market, with all its technology and
portability, truly the digital camera is the future of cameras.
