Digital Zoom Versus Optical Zoom

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

The optical zoom works like the zoom on a 35mm film camera. It changes the length of the lens of the camera and approach the subject to get closer. The optical zoom keeps the image quality. Digital zoom works differently. Just take the photo and cultures at the same time expanding the remaining portion. This makes the photo quality is reduced considerably.

What this means in terms of production, an enlarged view of an object with the digital zoom, but chances are your image will be blurred. The details are lost. In fact, it is the best, the digital zoom function on the camera if possible to disable. This prevents automatically zoom to the close as the digital zoom is often an extension of the optics.

There are some things you do when you can wish for a closer look at a topic, but the image quality is still good. Try everything and under the photo. Often only a foot or two will do. If this is not possible, you can take your camera a picture of their file size bigger. This will result in an image that is cut to only include the desired topic, however, allow an image that remains clear is.

Digital zoom has its place. Can be used if the only goal of the photo is the Internet. Online photos can be much lower quality in the camera and still appear acceptable when e-mail or post on a web gallery. If your destination is the impression, however, is looking for an off camera with more optical and digital zoom. Your pictures are better in the end, but not so close.
