Many digital cameras offer both digital and optical zoom. These two often confuse the average camera buyer, until you know what you are looking for.

The optical zoom works like the zoom on a 35mm camera film. It changes the length of the lens of the camera and the subject draws near you. The optical zoom keeps the image quality. Digital zoom works differently. It just takes the image and crops it then extends the part that is left. It causes the quality of the image must be reduced, sometimes significantly.

What this means in terms of production is that you can have a magnified view of an object with the digital zoom, but chances are your image will become blurred. The data will be lost forever. In fact, it is preferable to disable the digital zoom on the camera if possible. This will automatically zoom close enough to avoid the digital zoom is often an extension of optics.
There are some things you can do if you want a closer view of a topic, but want the quality of your picture is still good. Try to move over when you shoot. Often only a foot or two will do. If this is not possible, you can set your camera to take a picture in their file size higher. This will result in an image that can be reduced to include only the desired subject, while allowing an image that is always clear.Digital zoom

Digital zoom has its place. It can be used if the only destiny of your photo is the Internet. Online photos can be a much lower quality in the camera and still appear acceptable when sent by e-mail or posted on a web gallery. If your goal is to print, however, require a camera that has a greater optical zoom and digital zoom off. Your photos will improve over time, even if they are not so close.
