Basic Features Of Digital Cameras To Consider

Regardless of brand names, digital cameras have the same basic features that any consumer should know and consider before buying one. Even though digital cameras are generally a point and shoot device, certain features can often single out a particular brand or model. A good example of this is the term megapixel, which became known when digital cameras were introduced in the market.

Megapixels, which means millions of pixels, measure the quality and size of a digital camera. Pixels refer to the dots that make up a picture. Therefore a digital camera that has about a 5-megapixel resolution will produce better quality pictures compared to a 3-megapixel digital camera.

Moreover, photos taken with a digital camera that offers greater megapixels can be enlarged safely without sacrificing the quality of the picture. Average digital cameras with less than 3 megapixels often forfeit the clarity of the picture once it is enlarged. Unfortunately, there is a downside to using a digital camera with greater megapixels as they consume more of the camera’s memory.

The zoom function of a digital camera is another feature that most consumers should consider. There are generally two types of zoom features for many of the digital cameras on the market today. The optical zoom feature is common in devices without permanent lenses. The user can simply zoom and focus on the subject to be photographed.

A digital zoom feature is similar to using an editing software program for images. In most cases, a digital camera may offer both types of zoom features. Most digital camera users recommend concentrating on the optical zoom feature to validate the quality of the device.
