Close up and personal - choosing the right
Zoom
The zoom function on a camera allows you to "zoom" in on a specific
part of the picture you are taking without having to physically move
closer to it.
Digital cameras use two types of zooms, digital and optical.
Understanding how these features work will help you select the
combination that it right for you.
Optical zoom behaves in the same way that traditional film cameras
do, using lenses to magnify the image. In other words, optical zoom
brings you closer to the picture. This is the preferred method of
taking a close up picture, mainly because optical zoom does not
negatively impact the resolution of the image. The general standard
for optical zoom is 3X (which indicated a threefold magnification of
the image). Higher optical zoom is offered on many models, although
upgrading optical zoom will influence the price.
Digital zoom, on the other hand, takes a portion of the image, crops
it and expands the pixels to magnify the image and brings the
picture closer to you. One of the negatives to the digital zoom is
that it diminishes the quality of the image by making the pixels
bigger.
Close ups using digital zoom can also be done after the picture is
taken using an image manipulation software package (included with
most cameras).
