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.
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.
Things You Need to Know Before You Buy Digital Camera
Digital cameras come in many sizes, colors, brands, zooms, resolutions, playbacks, etc. There are so many features and qualities that are being placed in the devices that buyers especially first timers become overwhelmed and dizzy with these outstanding arrays of gadgets. This is even without including the various advertisements and different ratings that are used to promote these products.
So what are the things to look for if you want to buy digital camera? To be able to answer these, there are 2 sets of information you have to know before you can decide. The first type of information is defining what YOU need and want in a digital camera. To do this, you can ask yourself the following questions:
- What do you want to take with your digital camera? Before you buy digital camera, it is important to determine what kind of pictures you want to take with it. If you are a digital photography enthusiast, any digital camera will not just do. You have to look for features that can support the zooming you need, the resolution, etc.

Editing software are already included when you buy digital camera but other devices aren’t. Aside from a printer, ink and paper for printing, you might also need additional memory cards for your camera and a more powerful computer to support image editing and image storage and retrieval.
After answering these 3 questions, the second set of information you need to know before you buy digital camera are the features that you need in the device. These are:
- Resolution. Before you buy digital camera, check first its capacity to produce high quality photo images. The number of pixels indicated determines resolution. The more number of pixels, the higher the resolution which can make photos to be enlarged without losing image quality.
