DIGITAL CAMERA: THE FUTURE OF CAMERAS
Basically a digital camera is a device 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.
The computer then goes ahead and breaks down the information to digital data which produces the results of the 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.
Some low end digital cameras use complementary metal oxide semiconductor or CMOS as an image device, there is still a possibility that it can get better and more famous, however, most engineers do not think that it can replace the CCD that current high-end digital cameras have.
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
One of the major reasons why the price of the digital camera has been slowly fluctuating is because of the introduction of the CMOS image sensors. CMOS sensors are cheaper and easier to manufacture then the 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 you go out to get your own digital camera, here are some things that you can take note of.
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.
Options. This will help you impress your friends on how good a photographer you’ve become. Find a camera with options to suit your lifestyle, this way there won’t be any reason to whine about not being able to 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.
