Automatic Mode — A setting that sets the focus, exposure and white-balance automatically.

Burst Mode or Continuous Capture Mode — a series of pictures taken one after another at quickly timed intervals with one press of the shutter button.

Compression — The process of compacting digital data, images and text by deleting selected information.

Digital Zoom — Cropping and magnifying the center part of an image.

JPEG — The predominant format used for image compression in digital cameras

Lag Time — The pause between the time the shutter button is pressed and when the camera actually captures the image

LCD — (Liquid-Crystal Display) is a small screen on a digital camera for viewing images.

Lens — A circular and transparent glass or plastic piece that has the function of collecting light and focusing it on the sensor to capture the image.

Megabyte — (MB) Measures 1024 Kilobytes, and refers to the amount of information in a file, or how much information can
be contained on a Memory Card, Hard Drive or Disk.

Pixels — Tiny units of color that make up digital pictures. Pixels also measure digital resolution. One million pixels
adds up to one mega-pixel.

RGB — Refers to Red, Green, Blue colors used on computers to create all other colors.

Resolution — Camera resolution describes the number of pixels used to create the image, which determines the amount of
detail a camera can capture. The more pixels a camera has, the more detail it can register and the larger the picture can be
printed.

Storage Card — The removable storage device which holds images taken with the camera, comparable to film, but much smaller. Also called a digital camera memory card…

Viewfinder — The optical “window” to look through to compose the scene.

White Balance — White balancing adjusts the camera to compensate for the type of light (daylight, fluorescent, incandescent, etc.,) or lighting conditions in the scene so it will look normal to the human eye.

  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.

After spending sizable amount of time at the mall figuring out which is the best digital camera for us, we finally have enough money to buy for that eye-popping, 7 mega pixel, 10x digital zoom, potable, candy colored, up to 512MB expandable memory of super hi-speed SD memory card and not to mention very portable, (that will be the envy of almost everyone we know). We march to the mall armed with our life savings and lots pride in ourselves, when we pass by a new display – an eight mega pixel, up to 1G expandable memory, with built it mic and stereo surround, video playback capable, with 22 scenic modes kind-of-camera. And we sigh because the producer of this amazing gadget claims that this is the best digital camera yet out in the market. And so as we always want to have the best, armed with our life savings and a few credit cards, we buy the “best digital camera.” But then again, that doesn’t last too long, after two months or so, there’s another “best digital camera.”

And so it confuses us. What makes a digital camera, the best digital camera?

Well, there are certain factors to consider when looking for the “best digital camera” for us.

MEGAPIXELS: One of the most important features of digital camera to make it into the best digital camera category is its mega pixel property. The higher the mega pixels the better the actual photograph will come out. A mega pixel is equivalent to one million pixels. The resolution of your image is based upon the mega pixel property of your camera. This means that as you enlarge the picture, you would get more detail and less blurry colors.

LCD SIZE: The best digital camera will always have a large LCD to help you frame your subject without having to squint to the viewfinder. This is also helpful when reviewing your images, some cameras enable touch up and editing features with its LCD. A 1.5-inch display is average, a 2-inch LCD display is good, but the best LCD size would be 2.5 inches or higher.

ZOOM: Most digital cameras have both digital and optical zoom. A higher optical zoom is always better than a higher digital zoom. Digital cameras are usually furnished with optical of between 3x to 10x. The better the optical zoom, the higher it climbs up to the best digital camera category.

MEMORY CARD: Always make sure that your memory card is the right one for your digital camera. There are different types of memory card like the XD, SD, Flash card and the likes. And these types of memory cards go with certain types of digital cameras. of course memory storage is also up there in choosing the best digital cameras. Choose the size of memory that you need, if you’re a photo junkie, you might need more than 32MB. Memory cards can go up to 1G.

The key point to find the best digital camera is to find one that will best fit you and your lifestyle. Don’t just buy the latest or the one that claims they are the best digital cameras out in the market. You wouldn’t want to buy a DSLR and use it with your home activities or family outing and have to lug it around?! Or you don’t want to buy the latest point and shoot camera when you’re serious about being a professional photographer. (Of course, you can use this for starters, but if you’re not a novice photographer anymore, you wouldn’t want to get this kind of camera.)

Actually, the best digital camera is the one that you will enjoy and use. Not the type that you’ll just leave rotting in its box or after a few weeks of usage or so, up there in the attic.
