If you are thinking of purchasing a digital camera in the near future then you should get familiar with certain terminologies. Being aware of frequently used terms and understanding them will not only make you better-informed to select the right digital camera, but will also help you to have better control over the features available in your digital camera to take photos of best possible quality.

Here are some of the basic digital camera terms that you should know about.

Megapixel

Megapixel refers to the maximum resolution that a photo can be taken using a digital camera. For instance, a camera with 4 megapixels can produce photos that contain 4 million pixels each. In simpler terms, it is a measure of quality. The higher the megapixel count of a digital camera, the higher will be the quality of the photos taken. To take quality photos digital cameras with megapixel count of 3 or more is recommended, especially if you want to make prints of the photos.
Digital zoom
Digital zoom is usually given more attention than it actually deserves. Digital zoom is entirely different from optical zoom. While optical zoom makes use of physical lenses present inside the camera to enlarge a particular scene, digital zoom enlarges the pixels around the center part of a photo electronically. This means that whenever you opt to use the digital zoom feature you are compromising the quality of your photos. It is way better to disable this particular function if you want to take quality photos with your digital camera.
Focal length
Focal length, as opposed to digital zoom is often overlooked by most amateur photographers. This term is a measure of to what extent the camera lens can enlarge a shot. There are two types of focal length, the wide-angle which is a better option for spacious shots and the telephoto which is better for shots with a narrow field of view.

Though wide-angle lenses are best suited for most of the photos commonly taken by most people, like group photos and landscapes, they are found in very few digital cameras because manufacturers find it far easier to produce telephoto lenses. In short, digital cameras with wide-angle focal length are a better choice for most people’s needs.
Shutter lag
Shutter lag is the time difference between pressing the button to take a shot and when the picture is actually taken. While the difference is very insignificant it does affect the picture and if the lag time is more you might not get the picture that you desired. Most often the shutter lag time is not listed by the manufacturers of digital camera. A best ways to check it out is to test the camera before making your decision.
