The Facts Of Zooming
By Jakob Jelling, Fri Dec 9th

Zooming is often seen as a great tool which could actually makea more expensive and valuable. Many times, we think acamcorder with a powerful zoom is much better than other whichdoes not offer such characteristic, but not always this is sucha great quality as we would think.

Many times, when we use our zoom, we loose imagequality. Zooming increases the image size by amplifying pixelswhich actually causes the subject to loose resolution andquality. The more you zoom in, the more pixels become amplifiedand the more image quality you loose.

This way, whenever possible, it is always highly recommendableto actually approach the subject you wish to zoom in instead ofusing this camera feature in order to avoid loosing quality.Therefore, whenever possible you should try to avoid zoomingand, instead of it, simply walk closer. Whether you are using ananalog or a digital one, by moving closer to yoursubject you would maintain your video or image quality in a muchhigher level than if you used the zoom.

Digital

zooming can be evaluated depending on the optical zoomlevel. According to the optical zoom a digital camera has,zooming in with it would allow you to have a good or a not sogood image resolution and quality. The more powerful an opticalzoom is, the less resolution you would loose. This way, if youwish to acquire a digital camera which would allow you to zoomin by loosing the less amount of quality possible you should payattention to its optical zoom more than to the digital zoomitself.

Digital zoom numbers do not really tell much of a digital camerazooming quality. Actually, digital zooming has no limit; it ispossible to create digital cameras which offer a digital zoomingas powerful as they wish. The digital camera feature whichallows us to measure its zooming quality is the optical zoom,and it is recommendable to pay attention to that characteristicrather than to the digital zoom numbers before acquiring a newdigital camera.
