Planning to buy a digital camera? Not sure how to get started?
Read on to discover how…..
1. What do you need the camera for?
If you buy a simple one that can be used at home, you will not get interesting capabilities that you need for taking really good photographic pictures. On the other hand, it would be a waste of your money if you have the latest digital camera only to be used for personal photos at home.
Based on the purpose one can choose from the following main three types.
• Point and shoot: - reasonably compact, with features and size like 35mm cameras.
• Lifestyle: - with moderate features, it’s sleek and compact, so you can carry it around with ease.
• Professional: - with interchangeable lenses, flashes and other accessories, this camera is robust and feature laden, just the right choice for a professional or serious photographer.
2. These are the important features to look for?
Pixel resolution
Digital images are made up of dots called pixels. The higher the number of pixels in your image, the better will be the quality of the image. This will therefore enable you to enlarge your image to higher pixel dimensions without creating a pixilated (broken) image.

Compression

Compression shrinks a photo's file size, thus accommodating more images in the memory card. However compression causes a small amount of data loss. If you need the absolute best-quality images, you have to consider buying a camera that takes uncompressed photos but will accommodate less number of images.

Memory

A camera's memory size will decide the number of images that can be stored. Memory of 128MB will be good enough if you want to use the camera mostly at a social do or a party. If you are on a vacation or when you cannot download images for days at a stretch, a memory of 512MB to 1GB will be most favorable.
LCD screen
Most digital cameras come with at least an optical viewfinder but many digital cameras also come with an LCD screen built into the back. For a digital camera, they vary from 1.5-2.5 inches.

Lens
It is the length of a camera's lens that determines how much of a scene will fit in a picture. A "Normal" lens is about 50mm, most closely approximate to what your eye sees.
Optical zoom
This enables the photographer to zoom in on an object without any problem in picture quality. Depending on the magnification number, you can zoom in more.
Digital zoom
This feature enables the photographer to zoom in on the centre of the picture by removing the edges of the image.
Focus an exposure

In most cameras, the correct exposure for the lighting conditions is automatically determined. A camera rated ISO 100, has approximately the same light sensitivity as that of a traditional film camera loaded with ISO 100 film. A higher ISO rating means that the camera is more sensitive to light and is potential enough to take pictures in darker settings.
