Chapter 2. Buy Your Camera Gear > Resolution and Megapixels

Resolution and Megapixels

The resolution of a digital camera refers to the amount of detail the camera records when you take a picture. It's expressed in megapixels, which is a measurement of the number of sensors the camera uses to record the picture. The more megapixels, the better the picture and the more things you can do with it. But the importance of a camera's resolution depends on the kinds of pictures you want. If you use a picture as part of a Web page or to make a small print, you won't see much difference between a top-of-the-line camera and a basic consumer model. If, on the other hand, you make a large print, the difference will be all too obvious (Figure 2.1).

Figure 2.1. This picture looks pretty good at its original size. When enlarged, the lack of detail in the original begins to show.
