It helps when learning to use your new digital camera to also know what some of the more common terms mean. Below you will find many of these common terms defined..
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.

Before Buying A Digital Camera Check The Mega Pixels
Digital photography is a booming business and is slowly going to take over the film camera market. Compact digital cameras are the most popular and common of the camera types. To get a better quality picture you need to increase the number of pixels, so the cameras with more mega pixels will have a sharper image. Underwater digital cameras are small and lightweight, and the quality is comparable to film if you go for the higher resolution shots. Digital pictures have improved dramatically, and are now incredibly clear. The main problem that most have is that after the picture is taken many people don't develop the pictures or don't have a a way to do it.
How exactly does it differ from the traditional camera? Up to the point when the image is captured, the process is the same in both. When you release the shutter the mirror moves out of the way and the image is captured in the same way as any digital camera. Zooming in on a subject works by cropping some of the image out of the picture. The thing to remember is the higher the resolution, the more realistic the image is, matching closest what the actual image is. The image is then enlarged to fill the camera frame, by doing this you will loose the quality of the photograph. If an image is too bright or too dark you can re-take the image.
Digital cameras are not that expensive today a 2 mega pixel camera can be had for less than $50. Also important to note is the memory capacity of the camera. In other words, how many pictures will the camera hold? Understanding a little bit about how pictures are recorded on a digital camera and then subsequently saved on a computer is critical but fairly simple even for a beginner. The key to getting the best possible digital pictures is to make sure the right camera is bought. Digital cameras are becoming more and more popular. Whether your pictures are good or bad it does not matter, with a digital camera you have full control.
In burst mode the camera shoots a fast series of photos for as long as the shutter button is held down or until the camera’s memory is full. In this mode the camera writes the photos to a temporary memory which is very fast but small. When the shutter button is released or the memory is full the camera starts the slow process of writing the photos to the flash memory. Memory is also a very important issue to consider.
In terms of features it may not have any more than a simple point and shoot model. Picture quality is normally an improvement from the more basic cameras. The price of a digital camera printer is lowering whilst the quality is increasing. As far as image quality is concerned, there are a couple factors - picture resolution, presence of noise in the camera, dynamic range, and the color quality of the image. Depending on the camera purchased and the accuracy of the settings, the quality can rival and sometimes even surpass a regular 35mm camera.
Basically, a mega pixel is capable of storing a million bits of information about a photo. Because the digital SLR cameras are more professional, they come with a hefty price tag.

The facts of zooming
Zooming is often seen as a great tool which could actually make a camcorder more expensive and valuable. Many times, we think a camcorder with a powerful zoom is much better than other which does not offer such characteristic, but not always this is such a great quality as we would think.
Many times, when we use our camcorder zoom, we loose image quality. Zooming increases the image size by amplifying pixels which actually causes the subject to loose resolution and quality. The more you zoom in, the more pixels become amplified and the more image quality you loose.
This way, whenever possible, it is always highly recommendable to actually approach the subject you wish to zoom in instead of using this camera feature in order to avoid loosing quality. Therefore, whenever possible you should try to avoid zooming and, instead of it, simply walk closer. Whether you are using an analog camcorder or a digital one, by moving closer to your subject you would maintain your video or image quality in a much higher level than if you used the zoom.
Digital zooming can be evaluated depending on the optical zoom level. According to the optical zoom a digital camera has, zooming in with it would allow you to have a good or a not so good image resolution and quality. The more powerful an optical zoom is, the less resolution you would loose. This way, if you wish to acquire a digital camera which would allow you to zoom in by loosing the less amount of quality possible you should pay attention to its optical zoom more than to the digital zoom itself.
Digital zoom numbers do not really tell much of a digital camera zooming quality. Actually, digital zooming has no limit; it is possible to create digital cameras which offer a digital zooming as powerful as they wish. The digital camera feature which allows us to measure its zooming quality is the optical zoom, and it is recommendable to pay attention to that characteristic rather than to the digital zoom numbers before acquiring a new digital camera.
