Consumer Reports Digital Cameras Details
Buying a digital camera can be disorienting. There are
hundreds of cameras available at many different types of retail outlets
(online and in traditional stores), with prices ranging from $75 to
several thousand dollars. Some cameras are small enough to fit in a
shirt pocket. Others are large and can weigh up to two pounds. Some are
easy to use. Others look like you need an engineering degree to operate
them. And almost all are advertised with abbreviations that can be
cryptic and confusing for the novice. In this digital camera guide, we
aim to help you overcome some of this confusion.
What is a digital camera?
The first step is to understand what a digital camera is.
With a film camera, an image is formed by collecting light from a
particular scene or subject and focusing on film, which reacts
chemically when struck by light and is said to "capture" the image. What
makes a camera "digital" is that, instead of film, it has an image
sensor that reacts to light by sending out electrical signals.
The camera takes the information from the image sensor and processes and stores it as a collection of pixels in a digital file, usually on a memory card inside the camera. Although the actual process is more complex than that, in essence it is how a digital photo image is made. It's essentially made up of thousands and thousands of tiny dots, or pixels.
