THE FUTURE OF CAMERAS

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.

Take Better Pictures With Your Digital Camera

Better Picture
Today’s cameras make taking pictures a lot easier than the one’s of yesterday. There is always room for improvement, however. Use the following tips to help make your photos go from acceptable to great.
1. Always be aware of the background. You don’t want to find trees growing out of people’s heads or a passing vehicle to draw attention from your subject. Sometimes moving your subject just a couple steps to either side can make all the difference.
2. Use available light. If your digital camera has an option to turn the flash off and it’s light enough outside to read a book then use the available light and turn the flash off. In general camera flashes are too harsh for human skin and make all of us look pale. Indoors, where there isn’t enough daylight, place your subject by a window and use your fill flash feature.
3. Aim your camera slightly down at the person’s face. Also don’t shoot just face on to the person, try a little to the side, a three quarter view, so that you see more of their face. Remember camera higher looking down and a three quarter view, it will slim your subject.
4. Remember your focus. Get closer to your subject. Fill the frame with your subject and there will be no doubt as to what the picture is saying.
6. Never put your subject dead center. Put your just slightly off center; not a lot just a little. When you’re shooting groups of people, find the imaginary center line of your group and put that line just a bit off center in your view through your lens or screen.
Following these tips won’t turn you into an award-winning photographer today, but you will be on your way to better, more powerful photographs
