Buying Guide to a Digital Camera

The Big Picture

So you’re in the market for a digital camera. Megapixels, USB ports, optical vs. digital zoom—how do you know what you need? Digital cameras come with a wide variety of options, and you need to know what you are looking for before heading to the store. Digital cameras have come down in price in the last three years, but they are still a significant investment, and you need to make sure you get the most for your money.

Features of a Digital Camera

While the styles and varieties of digital cameras abound, they all have similar features. The first thing you are going to need to determine is the amount of resolution you need. Resolution in digital cameras is measured in megapixels. Let me explain what megapixels are and how they work.

In any digital image, whether on screen or in print, the actual image is made of tiny dots, called pixels. The more pixels that are in each inch of the picture, the smaller the dots are, and the clearer the image. A megapixel is one million pixels. Now, resolution is extremely important if you are planning on printing your pictures, especially if you are planning on making enlargements. A resolution of three or four will be sufficient for every day pictures and prints. However, if you are going to need quality enlargements larger than 8 x 10, you will need at least a five-megapixel camera.
